The best RV sewer hose kits give you a thick-walled hose that springs back after being run over, a fitting that seals to your RV’s outlet, and an adapter that covers the dump station pipe you actually pull up to. The Camco Deluxe 20ft kit is the one we keep reaching for: 18 mil vinyl, pre-attached 360-degree swivels, a removable 4-in-1 adapter, and a transparent elbow so you can see the last of the black tank go.
A sewer hose is the least glamorous and most failure-prone part of an RV. When it splits, you find out in front of strangers, and a kinked hose that will not drain backs the whole job up. That is why we weighed the specs first, mil thickness and fittings and collapsed length, then read through thousands of owner reports to see which hoses still feel supple after two seasons in the sun.
All eight kits below were compared on the same criteria, and each one ships with the pieces you need for a complete dump. We also flag where the cheap options genuinely cut corners, and how to flush your fresh water system properly, since the grey tank is what you use to rinse the hose out afterwards.

1. Camco Deluxe 20ft Sewer Hose Kit 39658 – Best Overall Pick
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
20 ft total
18 mil HTS vinyl
Removable 4 in 1 adapter
Clear elbow and extender
5 lb
Pros
- Transparent elbow and extender show when the tank is empty
- Pre-attached 360 degree swivel fittings connect from any angle
- 18 mil wall resists pinholes
- Each 10 ft section compresses to about 23 inches
- Elbow adapter and four end caps in one box
Cons
- Very flexible corrugated body does not stay put once run
- Some owners report pinhole leaks after limited use
This is the kit we put in our own bumper storage, and after a full season of use it still uncoils without a fight. Two 10 ft sections of 18 mil super heavy-duty HTS vinyl give you 20 ft of reach, and the 4 inch outside diameter matches the square bumper bay most trailers are built around.
The fittings arrive already attached, so there are no clamps to lose in the grass and no assembly step to get wrong. The swivel on each end rotates a full 360 degrees, which is what stops the hose from twisting against itself when you lay it out to a dump station.
The transparent elbow and the clear extender are the two parts we would not go without. Instead of guessing whether the black tank emptied, you watch the last of it travel down the line, and owners consistently single those two pieces out as the reason the kit feels well made. Four end caps seal the ends for storage, which matters more than it sounds if you travel with grey water still in the lines.
Spec-wise it is a 20 ft kit listed at 240 inches long and 4 inches wide, weighing 5 pounds, with a one year limited Camco manufacturer warranty. The removable 4-in-1 adapter covers a 3 inch slip inlet plus 3 inch, 3.5 inch and 4 inch NPT threaded connections, which is the range you will meet at almost every municipal dump station in North America.
What you get right at 23 inches of storage
Compression is where this kit quietly beats most of the field. Each 10 ft section collapses to roughly 23 inches, so a pair of them drops straight into a 4 inch square bumper storage tube with room for the elbow and adapter alongside.
That matters more than it sounds. A hose that will not compress becomes the reason people leave a sewer hose on the ground, and a hose left on the ground gets driven over. Ours went into the bay on the first try with no folding or forcing.
Where it falls short
The honest drawback is that this corrugated body is very springy. It resists lying flat once extended, so on a downhill site you may want a sewer hose support or a length of pipe to keep the run from creeping.
A smaller group of owners also reports pinhole leaks and spring leaks after limited use, and a few mention an outlet fitting that did not mate properly with their RV. None of these were dominant themes across thousands of reviews, but they are the reason we do not hand this kit the durability crown outright.
2. Camco RhinoEXTREME 20 Ft Kit – Best for Crush-Proof Durability
Camco RhinoEXTREME 20 Ft RV Sewer Hose Kit, Pre-Assembled, Swivel Fittings
20 ft total
24 mil TPE with exoskeleton core
4 in 1 adapter and four caps
1 year warranty
Pros
- 24 mil TPE shrugs off crushing and stepping
- Color holds and hose stays flexible outdoors
- Holds up to heavy full-time use and abrasion
- Pre-assembled fittings mean a fast hookup
- No leaking at the rotating ends for most owners
Cons
- Springy body resists compression for bumper storage
- The two halves are hard to separate by hand
- Occasional reports of pinholes in new hoses
If you full-time it, boondock on gravel, or have ever run over a hose and watched it stay flat, this is the kit. The construction is 24 mil thermoplastic elastomer with a reinforced polymer core exoskeleton, and owners describe it as the most durable hose they have owned after years of exposure.
It arrives pre-assembled with bayonet fittings and a transparent elbow swivel already in place, so a hookup takes the time it takes to walk the hose to the inlet. The kit also includes a 4-in-1 adapter and four storage caps, meaning nothing else is needed in the box.
The reported strengths are consistent: the color does not fade, the hose does not go brittle after a year outdoors, and the abrasion resistance holds up to full-time use. Camco customer service has also replaced defective sections for owners, which is worth knowing in a category where most sellers point you at a replacement.
Full-time RVers rate this one as the toughest option in our group, and the review volume of 4252 at 4.6 stars makes it one of the most proven kits in the category. The listed dimensions are 240 inches long by 3 inches wide, backed by a one year limited Camco manufacturer warranty.
The trade-off is storage, not strength
Each 10 ft section compresses to about 57 inches, which is well above the 23 inch figure of the Camco Deluxe. If your bumper bay is deep enough this is a non-issue, but owners with a shallow 4 inch square tube report a tight fit and a need for a longer holder.
The second quirk is separating the two halves. Multiple reviewers mention the sections are difficult to pull apart by hand, and that gets worse in cold weather when the TPE is stiff. Plan for that before you need the hose at a cold campground at dusk.
Who should pay up for it
This is the pick for full-time RVers, winter campers, and anyone camping off pavement where the hose will get stepped on. The 24 mil wall and reinforced core are the reason it keeps working after seasons of sun and cold.
If you are a weekend camper with a deep bumper bay and a paved site, you are paying for durability you may never use. In that case the Camco Deluxe gives you nearly the same experience with far better compression.
3. Camco Revolution 10-Foot Kit 39639 – Best Budget Pick
Camco Revolution 10-Foot Camper/RV Sewer Hose Kit – Features Pre-Attached 360-Degree Rotating Fittings – Includes Wire Guards (39639)
10 ft hose
15 mil HTS vinyl
360 degree swivel
Wire guards
2 lb
Pros
- Entry-level price with a complete fitting set
- Pre-attached 360 degree swivel fittings
- Compresses to about 2 feet
- Wire guards shield the hose ribs
- Patented design made in the USA
Cons
- 15 mil wall is thinner than the heavy-duty kits
- Only 10 ft of total reach at dump stations
- Fewer accessories than the two-hose kits
The Revolution is the one we recommend to a first-time RV owner or anyone who wants the smallest, lightest thing that works. At 2 pounds it is a fraction of the weight of the 20 ft kits, and it compresses to about 2 feet for storage in a 4 inch square bumper.
The fittings are pre-attached with a full 360 degree swivel, so there is no assembly and no clamp. The kit also includes wire guards, which protect the ribs on the hose from abrasion where it rubs against the storage tube.
At 15 mil heavy-duty HTS vinyl, the wall is thinner than the 18 mil and 24 mil options in this roundup, and the 10 ft total length is the shortest we tested. That is fine when the dump station sits close to your pad, and a problem when you have to cross a lot to reach the inlet.
What owners consistently rate highly is the swivel fittings and the portability. With 5208 reviews at 4.5 stars, this is the most reviewed short-hose kit in the group, and the sentiment is that it does exactly the one job it is built for.
When 10 ft is genuinely enough
Short hoses make sense in a small campervan, a pop-top, or any trailer where the storage bay is measured in inches rather than feet. The listed size is 120 inches long by 3 inches wide, with a one year manufacturer warranty.
Buyers also like that the wire guards take the abuse that normally cracks hose ribs. That is a small design touch that adds real life to a thin-walled hose, and it is why this kit outlasts cheaper generic 10 ft hoses in owner reports.
What you give up
Thin vinyl punctures more easily, and that is the trade you make for the lower weight and the tighter fold. If you camp on gravel or coarse grass regularly, this is not the hose we would put under a tire.
The accessory list is thinner too. There is no transparent elbow or multi-fit adapter listed in the box, so you may need to buy a dump-station adapter separately depending on the inlet you use most.
4. Thetford Titan 15-Foot Premium Kit 17853 – Best for Cold Climates
Thetford Titan 17853 15ft 15-Foot Premium RV Sewer Hose Kit-Thetford-17853, Black/Green
15 ft hose
Uncrushable TPE
ExtendGrip bayonet
5 in 1 adapter
4.5 lb
Pros
- Fused pre-attached fittings hook up in seconds with no clamps
- TPE body resists cracking in desert sun and cold
- Recovers from being run over or stepped on
- Adapter and caps included for no-mess storage
- Long-standing owners report years of service
Cons
- Springs open after compression and takes extra storage room
- The 90 degree dump elbow can pop off under tension
- 5 in 1 adapter does not fit every station
The Titan is the one to buy if your season includes freezing nights. Thetford states the uncrushable thermoplastic elastomer performs in extreme temperatures without becoming brittle, and that claim is the reason this kit sits in our group rather than a generic vinyl hose.
The ergonomic ExtendGrip bayonet fitting is fused to the hose at the factory, so the connection is sealed from the start and there are no clamps to tighten. Hookup is close to instant, and owners describe the ends as not leaking.
Thetford also includes the Revolve 5-in-1 sewer adapter with a handle, plus two end caps. The adapter is designed to fit any RV sewer outlet, and the handle is genuinely useful when the fitting is stiff, which for a thick-wall TPE hose it sometimes is.
At 15 ft the hose sits between the compact 10 ft option and the 20 ft kits, and it weighs 4.5 pounds. Buyers who stay with it tend to describe it as effectively indestructible, and the kit carries a 4.5 star average across 2745 reviews.
Why the 5-in-1 adapter matters
Most dump stations in North America present a 3 inch slip inlet or 3 inch, 3.5 inch and 4 inch NPT threaded pipes. A multi-fit adapter covering that range means you are not standing at the station deciding whether you need a different piece of gear.
The same logic applies on the RV side. Because the bayonet is fused rather than clamped, there is one connection point at each end instead of a fitting that can work loose, and that is where blowouts during a dump usually start.
The weakest link is the included elbow
Owners single out the supplied 90 degree dump-station elbow as the flimsiest component in the box, reporting that it can pop off under tension and that the handle feels light. If that happens, it is an accessory swap, not a failed dump.
The other recurring complaint is storage. The hose springs open again after compression, so it takes more bumper space than thin vinyl models, and owners with a short bay have cut the hose down to fit. Plan your storage length before you shorten it.
5. Valterra 20-Foot Dominator Kit – Best for Watching the Drain
Valterra 20-Foot Dominator RV Sewer Hose Kit, Sewer Hose for RV Camper, Includes 2 Attachable 10-Foot Hoses with Rotating Fittings, 90 Degree Clearview Sewer Adapter, and 4 Drip Caps
Two 10 ft hoses
23 mil wall
Clearview 90 degree adapter
Four drip caps
1 year warranty
Pros
- Two attachable 10 ft hoses give flexible reach
- Transparent Clearview adapter shows when draining finishes
- 23 mil wall holds shape while flowing instead of collapsing
- Bayonet-hook fittings rotate to stay flat and seal
- Four drip caps keep the bay clean
Cons
- 39 inch collapsed length per section is bulkier than Camco Deluxe
- Bayonet fittings can be stiff to mate and disconnect
- Some reports of leaks at the hose-to-fitting junction
The Dominator is the one we recommend to anyone who is anxious about a half-finished dump. The 90 degree Clearview adapter is transparent and fits six sewer connection types with a gas-tight seal, so you can watch the black tank empty and know when to close the valve.
The hose itself is 23 mil material that holds its shape in use to aid draining, which is the mechanical difference between a hose that flows and one that sags and holds a pocket of waste. Owners rate that shape retention as the main reason the kit feels better than cheap vinyl.
You get two attachable 10 ft hoses rather than one fixed 20 ft length, with pre-installed bayonet-hook fittings that form a leak-proof system. The rotating fittings keep the run flat and kink-free, and four drip caps come in the box for storage. The kit carries a one year warranty.
Long-term owners on the Good Sam Community forum specifically call out the Valterra Dominator as a hose that has held up well for them over the years. That kind of multi-year report is worth more than any spec sheet when you are deciding what to put in your bumper.
Two sections, more options
Because the 20 ft is split into two attachable 10 ft sections, you can carry 10 ft and reach only as far as you need on a close site, then use both when the station sits across the campground. For owners who relocate frequently, that flexibility is the main draw.
Long-term owners also point out that Camco and Valterra are seen as near-identical substitutes in most respects, which is why comparing them comes down to the adapter, the wall thickness, and how the hose stores.
Where owners report problems
The clearest weakness is size. Each 10 ft section collapses to 39 inches, so you need a longer bay than a kit that folds to 23 inches, and that is the difference between a hose that lives in the bumper and one that lives on the ground.
The bayonet fittings are also reported as stiff to mate and disconnect, and there are some reports of leaks at the hose-to-fitting junction. Separately, one Camper FAQs owner reported a crack in a Valterra hose after using it alongside a Camco and eventually switching to Camco, which is a reminder that UV embrittlement is the failure mode to watch for on any brand.
6. DUMPMAN 20 Ft Sewer Hose Kit – Best Complete Budget Kit
DUMPMAN RV Sewer Hose Kit, 2 * 10 Ft Sewage Hose
20 ft total
24 mil TPE and vinyl
Clear 90 degree adapter
Four end caps
2.63 kg
Pros
- Complete fitting set at a well below premium pricing
- TPE and vinyl blend springs back after being driven on
- Clear 90 degree adapter shows when the cycle is finished
- Accordion build collapses each section to 45 inches
- 4 prong bayonets carry rubber seals
Cons
- Thin-walled build is more prone to pinholes
- 45 inch collapsed length is the bulkiest two-hose kit here
- 4.4 average rating reflects more durability complaints
The DUMPMAN kit is the one we would tell a seasonal camper to look at first. You get 20 ft of total length in two 10 ft sections, a clear 90 degree adapter, and four end caps, which is a more complete box than most kits at this tier.
Construction is a TPE and vinyl blend rated at 24 mil with UV and abrasion resistance, built in a patented accordion pattern. Owners like that it springs back into shape after being stepped on or driven over, which is the whole point of paying for a thicker wall.
The fittings are 4-prong bayonets with built-in rubber seals for a leak-resistant connection, and the removable transparent elbow carries a 4-in-1 adapter that fits 3 inch slip and 3 inch, 3.5 inch and 4 inch NPT dump station pipes. The outside diameter is listed at 3 inches and the dimensions at 17 inches long by 7 inches wide.
With 1080 reviews at a 4.4 average, the pattern we see is consistent: satisfaction with the value and the complete fitting set, and a lower rating than the premium kits because of long-term puncture complaints.
A fuller box than the price suggests
Two 10 ft hoses, a removable transparent elbow, a 4-in-1 adapter and four end caps is the accessory list of a kit costing noticeably more. If you are outfitting a second RV or handing one of these to a family member, that completeness removes a separate shopping trip.
The accordion construction is also a good sign for storage behaviour. It folds down predictably, which matters when you are stuffing a hose into a bumper tube in the dark before moving on to the next site.
Where the money was saved
The wall is thin for a 24 mil listing, and thin walls mean pinholes. That is the theme in the reviews, and it is the reason we do not put this kit ahead of the Camco and Valterra options for full-time use.
Storage is the other issue. Each 10 ft section collapses to 45 inches, the bulkiest of the two-hose kits we tested, so measure your bay before committing. It ships with a 3 inch outside diameter, so it is also the narrowest of the 20 ft options in this group.
7. Amazon Basics RV Sewer Hose Kit 20 ft – Simplest Starter Kit
Amazon Basics RV Sewer Hose Kit, 20 ft, Black
20 ft total
Two 10 ft hoses
Four hose covers
90 degree 4 in 1 converter
4.5 lb
Pros
- Complete house-brand kit in one box
- Two 10 ft hoses plus four covers and a 4 in 1 converter
- 4.6 average rating with a high share of five-star feedback
- Backed by a straightforward return network
- Also offered in a 15 ft configuration
Cons
- Far fewer reviews than the branded kits
- Fittings and hose material are not specified in the listing
- Cover and adapter are the only listed accessories
This is the sensible first sewer hose. You get two 10 ft hoses for 20 ft of total length, four hose covers, and a 90 degree four-in-one ground converter adapter, which is everything a first dump requires and nothing you will not use.
Owners describe it as straightforward and easy to use, and the 4.6 average rating is high. The kit weighs 4.5 pounds and is also available in a 15 ft configuration if your storage or your site calls for it.
What we would caution on is thin data. With 172 reviews there is not yet a body of long-term owner reports about how the wall holds up after two seasons, and the listing does not specify the fittings or the hose material in detail, so the mil figure is not published.
That uncertainty is the honest trade for a house-brand kit. It is a reasonable place to start, and a reasonable place to upgrade from once you know your storage bay dimensions and how often you move.
Good for a first season
The four-in-one ground converter covers the same common dump station inlets as the multi-fit adapters on the premium kits, and the covers keep the ends sealed in storage. For a new owner who will dump two or three times a season, that is a complete and tidy setup.
It is also a sensible backup hose to keep in a bin. A second hose is genuinely useful in a full campground loop when the bay behind you is busy.
Why we do not rank it higher
Unspecified fittings mean you cannot compare the sealing hardware against the Camco or Valterra bayonet designs, and the accessory list is limited to the covers and the converter with no elbow listed.
Long-term durability data is the bigger gap. Forum consensus in this category is that you never patch a sewer hose, you replace it, and making a decision with 172 reviews behind it means accepting that you may be replacing sooner than you planned.
8. Valterra Silverback 20-Foot Kit – Best Abrasion Protection
Valterra D04-0675 20′ Silverback Sewer Hose Kit
Two 10 ft hoses
100 mil protective outer beading
Clear 90 degree adapter
5.9 lb
Pros
- 100 mil outer beading is the toughest exterior in this group
- Two 10 ft hoses with rotating fittings for flexible reach
- Springs back cleanly without taking a set
- Clear 90 degree universal adapter for most stations
- Long-term owners report no cracking and no odor
Cons
- Fitting seals are a recurring weak point
- Some reviewers find the wall thinner than the beading suggests
- One report of an end cap blowing off
The Silverback is built for hoses that get dragged across gravel and sand. Its 100 mil protective outer beading is by far the heaviest exterior in this roundup, and owners who stay with it point to that beading as the reason it survives rough handling.
You get two 10 ft hoses with rotating fittings, plus a clear 90 degree universal sewer adapter that works at most dump stations. The kit weighs 5.9 pounds, the heaviest of the two-hose options, and it is also made in a 15 ft length.
Long-term owners report no cracking and no sewer odor after draining, and the construction is polypropylene, which is the material Valterra also uses in many RV tank systems. For owners who already have Valterra fittings on the RV, matching the manufacturer keeps the parts interchangeable.
The spring-back behaviour is the other selling point. The hose recovers cleanly after compression without taking a permanent set, which means it still lays out flat and drains instead of bowing into a kink after a season.
Where the beading helps most
Corrugated hose walls crack at the ribs, and that is exactly what the beading reinforces. On a site where the hose runs over rock or coarse ground, that extra material is the difference between a hose that lasts and one that pinholes in its first year.
It also protects in storage. Hoses that rub against the inside of a bumper tube wear fastest at the ribs, and the beading takes that abrasion before the wall does.
The honest weak spot
Leaks at the connector seals are the consistent negative theme, reported at both the hose-to-hose and hose-to-RV joints. That is the junction that matters most, and it is where we would focus a water test before a long trip.
Some reviewers also describe the wall as looking thin once you account for the beading, and we saw one report of an end cap blowing off during normal use. At 4.4 stars across 387 reviews, it sits behind the leading Camco kits on proven consistency.
How to Choose an RV Sewer Hose Kit
Pick 20 ft unless storage stops you
Twenty feet is the standard reach because dump stations are rarely beside your pad, and two 10 ft sections give you the option of using only one when the station is close. A single 10 ft hose is fine for a small campervan and a tight storage bay, and it is the option to pick if you weigh every pound you carry.
Measure before you buy. Collapsed lengths in this group run from about 23 inches per section on the Camco Deluxe to 45 inches on the DUMPMAN and about 57 inches on the RhinoEXTREME, and a hose that does not fit your bay is a hose that ends up on the ground.
Read the mil number, not the marketing
Mil thickness is the most useful number on the listing. The kits here run from 15 mil vinyl through 18 mil, 23 mil, and up to 24 mil thermoplastic elastomer. Thicker is generally more puncture and crush resistant, and elastomer holds its shape better in cold weather than vinyl.
Are all RV sewer hoses the same? No. The differences that show up in owner reports are the wall thickness, whether the fittings are fused or clamped, and whether the hose returns to shape after being crushed. Those three things separate a hose that survives two seasons from one that does not.
Fittings decide whether a dump goes smoothly
Look for a bayonet fitting that is pre-attached and a multi-fit adapter covering a 3 inch slip inlet plus 3 inch, 3.5 inch and 4 inch NPT threaded pipes. Fused fittings have no clamp to lose and no screw to back out, and a 4-in-1 or 5-in-1 adapter means you are not shopping at the dump station.
RV sewer connections come in a few shapes: a bayonet with two hooks used on most travel trailers and motorhomes, cam lock style fittings on some aluminium trailers, and plain threaded outlets on a few imported models. That is the reason multi-fit adapters exist.
Accessories that change the recommendation
A sewer hose support keeps the run off the ground at the dump station, which removes most of the stepping and driving-over risk that thick walls are designed to survive. A macerator pump is a separate purchase that lets you dump into a home sewer cleanout rather than travelling to a station.
For winter use, drain the hose completely after every dump, coil it loosely, and keep it inside the RV or in an insulated bay. A freeze split is the one failure you cannot argue with, and it is why the Titan gets a nod for cold climates even though its storage is worse. Pair it with one of our recommended RV water filters so your drinking supply is not the weak link, and keep a garden hose reel on hand for the grey tank rinse after every dump.
Know when to replace it
Forum consensus in this category is that you never patch a sewer hose, you replace it. Watch for four things: pinholes or weeping under pressure, a hose that stays flattened after being stepped on, splits along the ribs after a season of UV exposure, and any leak at a bayonet or hose-to-hose joint.
Seasonal campers should plan on replacing every three years, full-time RVers every two. That is a usage-based cadence rather than a warranty, and it assumes the hose is stored drained and out of the sun between trips.
How to Connect a Sewer Hose at a Dump Station
Pull forward so the hose reaches the inlet without a kink, and lower the stabilisers before you open anything.
Fit the bayonet or cam lock fitting on your RV outlet, rotate until it locks, and check the seal by pulling gently on the hose.
Run the hose to the dump station and attach the transparent elbow or multi-fit adapter to the inlet, seating the rubber seal fully.
Set the adapter on the ground or use a sewer hose support so the run stays flat and downhill to the inlet.
Open the black tank valve slowly, then flush with the grey tank to rinse the hose and the tank lines on the way through.
Close the valve, disconnect the adapter first, cap both ends of the hose, and coil the hose loosely to drain before storage.
A water test before a long trip is worth the five minutes it takes. Fill a bucket, run it through the hose and the fittings, and look for weeping at every joint. A fitting that seeps under a slow trickle will absolutely leak under a full dump.
Frequently Asked Questions
What is the best brand of RV sewer hose?
Camco is the most proven brand in this category, with the most review volume across its RhinoFLEX, Deluxe, and RhinoEXTREME lines. Valterra is the closest substitute and is widely used on tanks and fittings already, while Thetford stands out for temperature performance and Lippert for connector hardware. The right brand matters less than the wall thickness and whether the fittings are fused.
What is the best length for an RV sewer hose?
Twenty feet is the standard choice because dump stations are rarely near your site, and two 10 ft sections let you use only one when the station is close. A 10 ft hose suits small campervans and tight bumper bays, and a 15 ft kit is a useful middle ground. Measure your storage bay first, since collapsed lengths vary widely.
What is the best black water drain hose for an RV?
A 20 ft kit with at least 23 mil wall, a fused bayonet fitting, a transparent elbow, and a multi-fit adapter covering 3 inch slip and 3, 3.5, and 4 inch NPT inlets will handle any black tank dump. Thermoplastic elastomer holds its shape better than vinyl in cold weather, which matters if you camp through the season rather than only in summer.
Are all RV sewer hoses the same?
No. The differences that show up in owner reports are wall thickness, whether fittings are fused or clamped, and whether the hose returns to shape after being crushed. Kits in this roundup run from 15 mil vinyl up to 24 mil thermoplastic elastomer, and the thinner hoses are the ones that develop pinholes first.
What size connection does an RV sewer hose typically use?
Most RV sewer hoses use a 3 inch bayonet fitting with two hooks to attach to the RV outlet, and some aluminium trailers use cam lock style connectors. At the dump station you will meet a 3 inch slip inlet or 3, 3.5, and 4 inch NPT threaded pipes, which is why a 4-in-1 or 5-in-1 adapter is worth having in the box.
Can I dump my RV black tank into my sewer cleanout?
In many jurisdictions you can, using a sewer hose with a cleanout adapter or a macerator pump, but rules vary by municipality and some areas restrict what may enter a home cleanout. A macerator pump lets you stop holding waste in the black tank at all, which is the quieter alternative to pulling into a busy dump station loop.
How do I keep my RV sewer hose from freezing?
Drain the hose fully after every dump, disconnect it from both ends, cap it, and coil it loosely rather than folded. Store it inside the RV or in an insulated bay rather than in an exterior compartment in freezing climates. A hose that has split from a freeze is a total loss, and a fitted cover is cheaper than a replacement.
Our Verdict on the Best RV Sewer Hose Kits in 2026
The Camco Deluxe 20ft kit takes our Editor’s Choice for one reason: it is the only hose in this group that pairs 20 ft of 18 mil wall with a 23 inch collapsed length, a clear elbow, and a removable 4-in-1 adapter. That combination of reach, monitoring, and storage is what almost every owner actually needs.
Buy the RhinoEXTREME instead if you full-time it or camp on gravel and you have the storage depth for a 57 inch section. Buy the Revolution if you want the smallest package, and buy the Titan if your season runs into freezing temperatures.
Tell us your setup and we will narrow it down: do you relocate every week, how deep is your bumper bay, and do you dump at stations or at home through a cleanout? And if you are outfitting the rest of the rig, our guides to RV surge protectors and RV covers cover the two other accessories worth buying before a season starts.
