If you live in your RV and dump the black tank roughly once a week, the Camco RhinoFLEX 20-Foot Complete Kit is the best RV sewer hose kit for most full-timers. It pairs 23 mil polyolefin reinforced with steel wire, a clear elbow so you can see when the tank is empty, and 4-in-1 adapter coverage in a two-section design that collapses to 39 inches for bumper storage.
A full-timer puts roughly ten times the wear on a sewer hose that a seasonal camper does. Fifty-plus dumps a year mean more abrasion from gravel, more UV exposure, more freeze and thaw cycles, and far more chances for a neighbor to back a truck over the line while you are connected at a dump station.
That is why we organized this roundup by usage frequency rather than by cost. We compared eight kits on wall thickness, material, collapse length, adapter coverage and the failure modes that actually end a hose’s life, and we flagged the ones whose hardware breaks rather than whose hose cracks. Our team also spends a lot of time in the RV maintenance and winterization side of this hobby, which shapes how hard we look at freeze performance.

Are all RV sewer hoses the same? No, and the two numbers that matter most are wall thickness and material. A 15 mil vinyl hose and a 24 mil thermoplastic elastomer hose can look identical in a photo and behave nothing alike after a winter of full-time use.
How Often You Dump Changes Which Hose You Need
Seasonal campers dump maybe five to ten times a year. Full-timers dump weekly, which adds up to more than fifty uses a year and roughly five hundred over a decade of living on the road. That single variable decides whether a budget vinyl kit is a sensible buy or a false economy.
If you dump weekly, you want 23 mil or thicker. Wall thickness is the defense against pinholes, and pinholes are the failure mode owners complain about most across RV forums. The trade-off is collapse length: heavier hoses spring back open and take more space in a bumper bay.
If you dump every two weeks or travel in mild weather, an 18 mil vinyl kit still works. Just expect to inspect it each season and accept that the material will not stay flexible as long in cold conditions.
Two other things change with high-frequency use. First, fitting hardware fails before hose material does, which is why we weigh the elbow and the bayonet tabs as heavily as the wall. Second, odor becomes a year-round problem rather than a spring problem, because you are washing and storing a wet hose in an enclosed bay ten times more often.
If your route takes you far from dump stations, more length is worth more than more thickness. We cover that in our guide to sewer hose kits with bayonet fittings, where adapter coverage matters most.
1. Camco RhinoFLEX 20-Foot Kit – Best Overall for Full-Time RVers
Camco RhinoFLEX 20-Ft Complete RV Sewer Hose Kit – Made in the USA
23 mil polyolefin with steel wire
4-in-1 adapter and clear elbow
Each section compresses to 39 inches
Pros
- Highest rated and most reviewed kit in the category
- Complete kit with two 10 ft hoses
- clear elbow
- 4-in-1 adapter and four caps
- 360 degree swivel fittings
- Adapts to 3 inch slip and 3
- 3.5 and 4 inch threaded station pipes
Cons
- Two sections mean extra connection work
- Separating the two halves is hard with reduced hand strength
- Occasional pinholes reported after extended service
This is the kit we keep reaching for, and the one that shows up most often in long-term ownership reports from full-time owners. The hose is 23 mil polyolefin reinforced with steel wire, which is a genuinely different material story from the vinyl kits at the other end of the market: the steel wire is what lets the hose hold a shape instead of coiling into a memory knot after a year in storage.
The clear elbow is the feature we notice most in the field. You can watch the last of the black tank leave the hose instead of guessing and pulling the fitting back onto gravel. The 4-in-1 adapter covers a 3 inch slip inlet plus 3 inch, 3 1/2 inch and 4 inch threaded station pipes, which is close to universal coverage across North American dump stations.
Each 10 foot section compresses to about 39 inches, so the kit stores in a 4 inch square bumper. That is longer than the Camco Deluxe but shorter than the RhinoEXTREME, which makes it the practical middle ground for a full-timer who wants a bumper bay they can actually close.
The one friction point reviewers raise consistently is separating the two 10 foot sections. It takes real grip, and it is the reason we would not put this at the top of the list for an owner with shoulder or hand limitations. Owners also report occasional pinholes after extended heavy service, which is a normal consequence of a polyolefin hose living outdoors for years.
Is the 23 mil polyolefin thick enough for weekly dumping?
Yes, for most full-time routes. Twenty-three mil reinforced polyolefin is the same thickness band as the 24 mil TPE on the RhinoEXTREME, and the steel wire reinforcement is what handles the abrasion and shape retention rather than the wall alone.
Where it is thinner than the top of the market is freeze performance, since polyolefin stiffens in deep cold. If your winter route keeps you in sustained sub-freezing weather with dumps at unheated stations, look at the heated sleeve option later in this roundup.
Where the RhinoFLEX falls short for a full-timer
The two-piece design adds work at every dump. You couple and uncouple an extra joint, and that joint is the most likely place for a slow weep if the seals dry out over an off-season.
Storage space is also a compromise rather than a win. At 39 inches collapsed, it fits a square bumper, but it will not disappear into a shallow floor compartment the way the Camco Deluxe does. If your bay is tight, that difference decides the purchase.
2. Camco RhinoEXTREME 20-Foot Kit – Best for Heavy Weekly Use
Camco RhinoEXTREME 20 Ft RV Sewer Hose Kit, Pre-Assembled, Swivel Fittings
24 mil TPE exoskeleton with reinforced core
Bayonet and clear elbow swivel fittings
Each section compresses to about 57 inches
Pros
- Heaviest listed wall among the flexible kits here
- Pre-assembled swivel fittings give a fast leak-free hookup
- Owners report surviving runovers
- freeze and full sun exposure
- Patented design manufactured in the USA
Cons
- Springy material makes bumper storage difficult
- Halves are hard to separate in cold weather
- Costs more than most two-section kits
This is the durability answer for a full-timer who dumps weekly and camps in busy loops. The 24 mil thermoplastic elastomer shell sits over a reinforced polymer core, and reviewers describe that exoskeleton as the reason the hose comes back to shape after a leveling jack or a tire rolls over it.
Hookup speed matters more than people expect when you are doing it fifty times a year. The bayonet fittings and transparent elbow swivel fittings are pre-assembled, so the whole connection takes seconds and, in owner reports, no leaks at the rotating ends.
What you give up is storage. The hose resists compression and springs back open, which is exactly what makes it tough on gravel and exactly what makes it hard to pack away. Each 10 foot section compresses to about 57 inches, so it fits a 4 inch square bumper only with the adapter removed, and owners with shorter holders report having to cut the hose to fit.
Separating the two halves is the second complaint, and it is worse in cold weather when the TPE is stiffest. Neither issue affects how the hose performs at the dump station, but both affect whether you will actually enjoy owning it on a daily basis.
Is 24 mil TPE overkill for a full-time RVer?
Not if your hose lives outdoors, sits in gravel or grass, and gets run over occasionally. The extra four mil over the RhinoFLEX is the difference between a hose that survives a decade of that treatment and one that pinholes toward the end of it.
It is overkill if you have a dedicated storage bay that swallows the springy coil comfortably and you dump every two weeks instead of weekly. In that case the RhinoFLEX gives you nearly the same wall thickness for less money and a shorter collapsed length.
What full-timers dislike about this kit
Storage, plainly and simply. The springy coil resists folding, and a hose that will not compress is a hose that ends up draped across a wet bay or wedged in a corner where it collects standing water.
Buyers also mention pinholes appearing earlier than expected in a small number of cases, though Camco customer service has replaced those hoses. The heavier springy material is simply harder on the fittings at the join when you are forcing two sections apart for the hundredth time.
3. Camco Deluxe 20-Foot Kit – Best Value and Tightest Storage
Camco Deluxe 20ft Sewer Hose Kit – Includes Features Pre-Attached Swivel Fittings & Includes Clear RV Sewer Elbow, (2) Heavy Duty 10ft Sewer Hoses, (2) Storage Caps, & Bonus Clear Extender – 39658
18 mil super heavy-duty HTS vinyl
Two 10 ft sections compress to 23 inches
Removable 4-in-1 adapter
Pros
- Tightest compression of any kit here at 23 inches
- Works well for both black and grey tank dumping
- Pre-attached 360 degree swivel fittings
- Clear elbow and clear extender show flow
Cons
- Vinyl wall is more prone to pinholes than TPE
- Very flexible so it crawls when unsupported
- Some kits arrive with an over-sized fitting or mismatched adapter
The Camco Deluxe solves a problem none of the heavy kits solve: storage. Each 10 foot section compresses to about 23 inches, which is the tightest collapse in this roundup and the difference between a hose that lives in a shallow floor compartment and one that does not.
The 18 mil super heavy-duty HTS vinyl is formulated to minimize pinholes, and with pre-attached 360 degree swivel fittings the hookup is quick. The transparent elbow and clear extender are genuinely useful on grey tank dumps, where you can see the water clearing instead of guessing.
For a full-timer on a route with mild winters and a storage bay that cannot take a 40 inch coil, this is the sensible buy. The same material and fittings also work well on grey water, which is the tank most full-timers dump more often than they realize.
The limitation is durability, and owners are honest about it. Long-term users report pinholes and splits in the vinyl after repeated use, and resort to tape or adding an extra section. That is exactly the pattern we would expect from an 18 mil wall living outdoors under UV for years.
Does an 18 mil vinyl hose last for a full-time RVer?
It can, with careful rinsing and storage, but it is the thinnest wall among the kits we rated highly and the one most likely to need replacing mid-life. Think of it as a hose you might buy twice over a decade rather than once.
The counter-argument is that a thinner wall is a wall that dries faster and folds smaller, and that a hose you can actually stow properly gets rinsed and stored properly, which does more for its life than another four mil of thickness.
When this kit is the wrong choice
Do not choose it if you camp in gravel loops, park under trees, or run your hose over rough ground. Vinyl scuffs and cuts, and those cuts are where pinholes start. The highly flexible material also springs away when released, so on an unsupported run it can crawl away from the station inlet mid-dump.
A few buyers also received kits with an over-sized fitting or a non-matching outlet adapter, so check the fitting sizes against your RV before you plan a route around this kit. If you are still deciding, our sewer camera buying guide covers the inspection habits that catch small leaks early.
4. Thetford Titan Premium 15-Foot Kit – Best for Desert Sun and Abuse
Thetford Titan 17853 15ft 15-Foot Premium RV Sewer Hose Kit-Thetford-17853, Black/Green
Uncrushable TPE hose
Revolve 5-in-1 adapter with handle
Ergonomic ExtendGrip bayonet fitting
Pros
- Uncrushable TPE that holds shape after a runover
- Fused pre-attached fittings give a leak-free hookup
- Seals well against 4-prong trailer fittings
- Performs in extreme temperatures without going brittle
Cons
- Only 15 feet of reach
- TPE will not compress into a short holder
- Elbow tabs can pop off under hose tension
Which is why the Thetford is the hose itself that wins in our view. It is uncrushable thermoplastic elastomer with high puncture and abrasion resistance, and owners report stepping on it, running a leveling jack over it and having it return to shape without leaking. That claim is the one manufacturers make most often and deliver least often, so it is worth noting that here it is corroborated.
Hookup is fast because the fittings are fused and pre-attached with a non-hardening silicone gel seal, so there are no clamps to lose and no threads to bind. The Revolve 5-in-1 adapter with handle and the ergonomic ExtendGrip bayonet fitting are both well regarded for sealing against 4-prong trailer fittings and dump station adapters.
Two hardware weaknesses show up repeatedly. The 90 degree drain elbow’s connection tabs and handle are reported as prone to popping off under hose tension, which has caused spills for some owners. And the adapter handle is awkward to thread in at a 90 degree angle once you are elbow-deep at a station.
The other compromise is reach. At 15 feet it is one of the two shortest hoses in this roundup, and a full-timer with dump stations scattered at the back of a park or across a loop will feel that limitation quickly.
Is 15 feet enough for full-time travel?
Enough if your dump stations are close and well placed, and short if you ever have to cross a campground loop or reach a station set back from the pad. Twenty feet is the more forgiving number for a rig that moves weekly.
If you want the Titan’s material with more reach, the practical move is to budget for a separate extension section rather than compromise on the hose you are happy to run over.
Why full-timers pick the Titan
The strongest case is climate. A full-time fifth wheel owner reports the Titan outlasting every cheaper hose tried in desert sun, and TPE holding its properties across wide temperature swings is the reason we would send a southern route to this kit.
The catch is storage, because TPE does not compress as tightly as vinyl. Several owners had to shorten the hose to fit a shorter holder, and the elbow tab issue means you should inspect that connection before every dump rather than trusting it indefinitely.
5. Valterra EZ Coupler 20-Foot Kit – Best Budget Kit
Valterra EZ Coupler 20-Foot RV Sewer Hose Kit for RV Camper, Includes 2 Attachable 10-Foot Hoses with Rotating Fittings and 90 Degree Clearview Sewer Adapter
18 mil plastic and vinyl construction
Each 10 ft section collapses to 25 inches
Transparent 90 degree adapter fits six outlet types
Pros
- Lightest kit reviewed at 1.9 pounds
- Collapses from 10 feet to 25 inches
- Rotating bayonet fittings keep the hose flat and sealed
- Transparent adapter shows when draining is finished
Cons
- 18 mil wall is among the thinnest here and less durable
- May not reach distant or elevated stations without an extension
- 6 percent of its reviews are one-star
The Valterra EZ Coupler is the one to pick if weight and storage matter more than wall thickness. At 1.9 pounds it is by far the lightest kit here, and each 10 foot section collapses to 25 inches, which is excellent for a bay with a shallow or awkward shape.
The pre-installed rotating bayonet fittings are the signature feature. They keep the hose flat and create a leak-proof connection, which is a real advantage when you are dragging a light hose across loose ground. The transparent 90 degree adapter fits six sewer outlet types with a gas-tight seal, so adapter coverage is broad.
As a backup hose, a starter kit for a new trailer, or a second hose to keep in the truck for routes where stations are frequent, the economics are hard to argue with. Two light sections are easy to carry and easy to wash.
For weekly full-time use, though, the 18 mil plastic and vinyl wall is among the thinnest in this roundup, and 6 percent of its reviews are one-star, with more of them than any of the heavy-wall kits. That points to material failing sooner rather than fittings failing.
Is this a good full-time RVer hose?
It works, and many owners run it for years without drama, but it is not the purchase we would make for a rig that dumps fifty times a year. Thin wall plus constant gravel abrasion is the combination that ends a hose early.
If your route is warm and your storage is tight, this is a defensible choice. If you are buying once for the next five years, put your budget into a heavier wall instead.
Where the Valterra falls short
Reach is the practical one. At 20 feet it may not reach a distant or elevated dump station without an extension, and a light vinyl hose is also easier to puncture on the sharp edges of a concrete bay.
Owners also note that the thinner material does not hold a bend as well, so on a downhill run to a pit station the hose tends to pull the connection rather than hold it. Pair it with a sewer hose support and the problem largely goes away.
6. DUMPMAN 20-Foot Kit – Best for Owners New to Full-Time Dumping
DUMPMAN RV Sewer Hose Kit, 2 * 10 Ft Sewage Hose
TPE with a 23 mil wall
4-prong bayonet fittings with rubber seals
Each 10 ft section collapses to 45 inches
Pros
- 23 mil TPE wall for a 20 foot kit
- Accordion construction springs back after being stepped on
- Clear 90 degree adapter with 4-in-1 fitting
- Four end caps included
Cons
- 45 inch collapsed length takes more bay space
- Narrower 3 inch diameter than the 4 inch hoses
- Shorter review history than Camco and Thetford kits
The DUMPMAN kit is the interesting value in this roundup. It puts a 23 mil wall and thermoplastic elastomer construction into a 20 foot kit, and it borrows the clear elbow and 4-in-1 adapter approach used on the premium Camco kits.
The accordion construction is what sets it apart from cheap vinyl. Owners report it springs back into shape after being stepped on, and the 4-prong bayonet fittings with built-in rubber seals give a leak-proof fit on a light hose, which is where cheap kits usually leak first.
For someone who has just gone full-time and does not yet know how hard their route is on hoses, this is a sensible first kit. You get heavy material and broad adapter coverage without paying a premium-brand premium.
Storage is the weak point. Each 10 foot section collapses to 45 inches, longer than every other kit here, and the 3 inch diameter is narrower than the 4 inch hoses in this roundup, so flow is a little slower on a long run.
Does a 3 inch hose flow slowly enough to matter?
On a long run to a distant station, yes, a narrower hose means more time holding a connection open and more chances for the fitting to shift. Most owners accept it, and a support keeps the line from sagging where the diameter matters most.
If your tank is large and you are not using a macerator, the difference in drainage time is noticeable enough that we would move up to a 4 inch kit once you know your route.
What to know before buying
The main caution is evidence. With roughly a thousand reviews behind it, this kit does not have the long ownership history of the Camco and Thetford products, so treat the durability claim as promising rather than proven over a decade.
Check your bay dimensions first. At 45 inches collapsed per section you need a deeper compartment than the other 20 foot kits, and a full-timer who cannot store the hose properly will end up storing it wet.
7. Lippert Waste Master 20-Foot System – Best for Controlled Dumps
Lippert 359724 Waste Master 20’ Extended RV Sewer Hose Management System , Green
Integrated CAM lock connector and ball valve
3 inch hose extends to 20 feet
90 degree discharge nozzle with view port
Pros
- Integrates a CAM lock connector
- ball valve and view port in one unit
- Permanently molded nozzle so nothing comes loose mid-dump
- Helical coil exterior resists abrasion while the interior stays smooth
- UV protected hose extends to the length needed automatically
Cons
- Heaviest kit at 9 pounds
- Permanently attached fittings are awkward to store and hard to clean
- Smallest review base among the 20 foot kits
The Waste Master is built around hardware rather than hose alone. You get an integrated CAM lock connector, a ball valve shut-off, a permanently molded nozzle with an easy-grip handle and a clear view port, and that combination is the one to consider if you want to stop the flow mid-dump without wrestling a fitting.
The helical coil on the outside resists abrasion, and the smoother interior is designed to keep waste moving instead of settling in the creases where odor starts. The hose is UV protected, extends to 20 feet and compresses to 5 feet 6 inches, holding whatever length your run needs.
The permanently connected nozzle is a genuine feature and a genuine inconvenience. Nothing comes loose in the middle of a dump, which is exactly what you want on a full-time schedule. It also means you cannot strip the hose down to wash it properly, and a permanently attached nozzle is awkward in a tight storage bay.
At 9 pounds it is the heaviest kit here, and that weight is felt every time you reposition the line at a station. The ball valve and view port are not things you need every time, but they are the reason this product exists.
Is the CAM lock connection better than a bayonet fitting?
It is a different trade. The CAM lock is designed as a time-tested leak-proof connection to the RV sewer outlet, and it is quick. Bayonet fittings are more common on trailer fittings and dump adapters, so check what your station and your RV actually use before committing.
Owners who want a single integrated unit with a shut-off valve tend to like this one. The trade is that you give up the ability to separate and deep clean the hose, which for a weekly user is a real consideration.
What full-timers should weigh first
Weight and handling. Nine pounds of hose and hardware is fine stored in a bay and genuinely awkward when you are wrestling a 20 foot line uphill at a station in the dark. If you dump in poor light, the 5 pound kits are easier to place accurately.
The smaller review base also means fewer long-term data points. If you want the valve and view port, this is the only kit in the roundup that offers them, and the helical coil interior is a solid reason to trust the flow characteristics.
8. REHOSEUP 15-Foot Heated Kit – Best for Freezing Climates
REHOSEUP 15FT Sewer Hose with Heated Sleeve,Black Heated Rv Sewer Hose kit
Electric heated sleeve runs the full hose length
23 mil polyolefin reinforced with steel wire
Elbow fitting with 4-in-1 adapter
Pros
- Only freeze-protection option in this roundup
- Reported to keep the line from icing in sustained sub-zero weather
- Sleeve stiffens the hose so it runs straight to the station
- Polyolefin hose with permanent no-leak fittings
Cons
- Needs a power source during use
- One buyer reported burn marks and a failed sleeve after one winter
- Shortest review base and only 15 feet of reach
Freezing is the one failure mode that ends a sewer hose outright. A hose that freezes solid is a hose that has to be replaced, and that is why this kit exists. The electric heating sleeve runs the full length of the hose with extra-long heating wire and thick cotton insulation, and owners in northern and snowy states report it preventing the sewage line from icing over.
A second benefit is geometry. The sleeve stiffens the hose enough to hold it straight and clear between the RV and the station, which takes a sagging line out of the equation in cold weather. The hose itself is 23 mil polyolefin reinforced with steel wire with permanent no-leak fittings, and the elbow carries a 4-in-1 adapter.
The constraint is straightforward: it needs power. If your dump station has no hookup, the heated sleeve does nothing for you, and that is the exact scenario a winter full-timer is most likely to face at a remote park or a big-box lot at 6am.
We would also be cautious leaving it energized for long stretches. One buyer reported burn marks on the sleeve and a unit that stopped working after a single winter, so treat the sleeve as a component with a service life rather than a permanent fixture.
Is freeze protection worth the complexity for a full-timer?
If you dump weekly in real winter conditions, yes, because a frozen hose means a contaminated cleanup rather than an inconvenience. If you winter somewhere mild or you always dump at stations with power, a heavy 24 mil TPE hose is the simpler answer.
Check your route before buying. The sleeve is most useful at unheated stations in sustained sub-freezing weather, which is a narrower set of stops than most full-timers expect.
Who should skip this kit
Anyone whose dump routine happens at a powered station, since the extra complexity and the only reported hardware failure both come from the electrical side. The 15 foot reach is also shorter than the 20 foot kits elsewhere in this roundup.
For most full-timers the heated sleeve is a seasonal problem solved by a seasonal approach: keep the hose fully drained, coiled loosely, and inside an enclosed bay until the weather warms. We cover that routine below.
How to Choose a Sewer Hose Kit for Full-Time Living
Wall thickness is the first filter, and the thresholds are simple. Fifteen mil vinyl is for occasional use, eighteen mil HTS vinyl is the budget band, and twenty-three to twenty-four mil in polyolefin or thermoplastic elastomer is the full-time band. Mil is a wall measurement, so the same number in two different materials still behaves differently, which is why we name both every time.
Length is the second filter, and it comes down to your route. Ten foot sections are standard. Fifteen feet is workable for close stations, and twenty feet gives you room to cross a loop or reach a station set back from the pad. If you cannot see a station from your rig, take the longer hose.
Adapter coverage decides whether the hose connects at all. A 4-in-1 adapter covers a 3 inch slip inlet plus 3 inch, 3 1/2 inch and 4 inch threaded pipes, which handles most municipal and campground stations. The Thetford’s 5-in-1 Revolve adapter and the Valterra’s transparent fitting that covers six outlet types go wider. A CAM lock system is a different interface entirely, so confirm what your station inlet looks like before you buy.
Storage geometry is the fourth filter and the one most people underestimate. Collapsed lengths in this roundup run from 23 inches for the Camco Deluxe to 57 inches for the RhinoEXTREME, and the difference dictates whether the hose lives inside your square bumper or draped somewhere it will never dry.
Finally, think about macerators versus a standard slinky-style hose. A macerator grinds waste and lets you use a much smaller diameter line, which is a genuine advantage when storage is the binding constraint. It also costs more, needs a 12V power source and adds another failure point, so for most full-timers a 20 foot 24 mil hose with a support remains the simpler system.
On the electrical side of a full-time build, off-grid capability usually comes first. Our RV solar panel kit guide covers the charge budget that keeps a macerator and heated sleeve running.
How to Dump Your RV Black Water Tank in 6 Steps
Dump the black tank before the grey tank, every time. Grey water carries shower and sink solids that settle into a black tank and turn the next dump into an unpleasant job.
First, close the grey water valve and the black water valve. Most tanks have a black valve on one side and a grey valve on the other, and confirming both are closed before you pull the fitting saves a soaked bumper bay.
Second, pull the RV sewer fitting out of the bay and cap the RV end. This stops sewer gas from entering the RV while the hose is disconnected, which is a large part of the answer to why an RV sometimes smells like sewer outside the bay door.
Third, connect the hose to the RV fitting, then connect the adapter to the dump station inlet. The transparent elbows on several of these kits let you confirm the connection is seated before you open anything.
Fourth, open the black tank valve and let it drain. Watch the elbow to know when the tank is empty rather than running the valve on a timer.
Fifth, add water to the black tank, close the valve, and run that water through the hose to flush it. The same goes for the grey tank afterward, in that order.
Sixth, close everything, disconnect, and cap both ends of the hose. Drip caps on the hose end matter as much as the cap on the RV, because a wet unsealed hose is what makes a bay smell for weeks.
How to Maintain and Store Your Hose Between Dumps
Extend the hose fully before you rinse it. A collapsed hose cannot be rinsed inside, and residual waste in the creases is a leading source of odor for full-timers. Water under pressure down the full length is the routine we recommend after every dump.
Then drain it, and let it dry before you coil it. A hose coiled wet in a closed bay is a hose that smells by the next morning, and no amount of rinse fixes waste that has had time to dry into the folds.
Coil loosely rather than tightly, and keep the fittings out of the pinch. A tight coil over months puts a memory curve into the hose that makes it harder to extend the next time, which is the complaint owners of the springier kits describe most often.
Before a long trip, lay the hose out and run water through it end to end. Pinholes and split seams show up as a stream rather than a drip, and finding them in your own driveway is far better than finding them across a campground loop.
Replace rather than repair when the failure is a split in the wall or a cracked fitting housing. Tape on a pinhole buys you a season at best, and a fitting that has popped apart once under tension is a fitting that will do it again. The lifespan question we hear most is how long a hose should last, and the honest answer is that a 23 mil or thicker hose in a full-time rotation often outlasts two thinner ones.
Frequently Asked Questions
What is the best brand of RV sewer hose?
Camco covers the most ground across this roundup, with the RhinoFLEX as the strongest all-round kit and the RhinoEXTREME as the most durable. Thetford’s Titan Premium is the toughest hose material for desert and abusive conditions. For a full-timer who dumps weekly and can store a springy coil, RhinoEXTREME is the answer; for everyone else the RhinoFLEX balances wall thickness, collapse length and adapter coverage better than anything else in the roundup.
What is the best length for an RV sewer hose?
Twenty feet is the most useful length for full-time travel because it reaches a station set back from the pad or across a campground loop. Fifteen feet works when stations are close and the hose only needs to reach the bay. Ten foot sections are the standard building block, so a 20 foot kit is two coupled 10 foot sections. Pick length before material if your route has long walks to the station.
What is the best black water drain hose for an RV?
For weekly black tank dumping, the Camco RhinoEXTREME 20-Foot Kit is the strongest choice, with a 24 mil thermoplastic elastomer exoskeleton and a reinforced core that survives runovers, freeze and full sun exposure. The Camco RhinoFLEX is the better all-round pick at 23 mil if storage space is tight. Anything in 18 mil vinyl works for occasional trips but pinholes sooner under weekly service.
Are all RV sewer hoses the same?
No. The three specs that separate them are wall thickness in mil, the material, and how well the hose collapses for storage. A 15 mil and a 24 mil hose can look identical while one pinholes after a season and the other survives years. Material matters as much as thickness, because thermoplastic elastomer and steel-reinforced polyolefin hold shape in cold and heat far better than vinyl.
What is the best RV sewer hose for long-term use?
Long-term full-time use points to the heaviest wall you can store. The Camco RhinoEXTREME at 24 mil thermoplastic elastomer and the Thetford Titan Premium with uncrushable thermoplastic elastomer are the two that hold up best across years of freeze, sun and abrasion. If your bay cannot take a 57 inch collapsed coil, the 23 mil RhinoFLEX is the better long-term compromise.
How long does an RV sewer hose last?
It depends on wall thickness, material, storage and how often you use it. A full-timer dumping weekly every year puts far more stress on a hose than a seasonal camper, and owners commonly report replacing an 18 mil vinyl kit within a few seasons while a 23 or 24 mil hose stays in service far longer. Storage matters as much as material, because a hose coiled wet in a closed bay degrades faster than one that is rinsed and dried.
Why does my RV smell like sewer outside?
The most common causes are an unsealed hose end, a hose coiled while still wet, and an open RV sewer fitting. Cap the hose end with the drip cap after every dump, extend and rinse the hose fully rather than collapsing it first, and let it dry before coiling. Also check that the bay door seal is intact, since a hose that never fully drains leaves a film that smells in warm weather.
How often should you dump a RV black water tank?
Dump when the tank is about two-thirds full at most, and never let it sit above that mark for long. A full-timer should expect to dump roughly weekly, which is exactly why wall thickness matters. Holding waste longer makes it denser, harder to move and more likely to clog a narrower hose, and a macerator changes the calculus because it can handle smaller volumes more easily.
What is the longest RV sewer hose you can buy?
Twenty feet is the practical maximum as a complete kit, because that is two standard 10 foot sections and it is what most manufacturers build around. Longer runs are made with separate extension sections rather than one long hose, since a 20 foot kit is already heavy and awkward to handle. If your station is further away than twenty feet, an extension section or a tote tank is a better answer.
Our Verdict for Full-Timers
Buy the Camco RhinoFLEX 20-Foot Complete Kit if you want one hose that handles weekly dumping, stores at 39 inches collapsed and covers almost every dump station adapter you will meet. It is the best of these eight RV sewer hose kits for the widest range of full-time rigs.
Upgrade to the RhinoEXTREME if you camp in crowded loops, run over gravel regularly or simply want the heaviest listed wall without changing your whole setup. Pick the Camco Deluxe if storage is your binding constraint, the Thetford Titan if your route is hot and your elbows are rough, and the heated sleeve kit only if you dump in sustained freezing weather without power at the station.
Whichever one you choose, the maintenance routine matters more than the model number. Rinse the hose fully extended, dry it before coiling, cap both ends, and test for pinholes before a long trip. That is how a hose survives full-time life.
