Best RV Sewer Hose for a First Travel Trailer
Buy the 20-foot kit. The 15 will reach at most sites, and then one day it will not. Everything else in this category is detail.

The short answer
Buy a 20-foot kit supplied as two 10-foot sections, with swivel bayonet fittings and a clear elbow. You use 10 feet at most sites and 20 when the connection is awkward, instead of coiling slack you do not need. The clear elbow is not a luxury — it is the only reliable way to know the black tank has actually finished draining.
This is the flagship page in our sewer and water guide, and it covers the part of RVing that nobody demonstrates at the dealership. Done properly it takes ten minutes and you never think about it again.

Who this is for
Someone who has a travel trailer, has worked out that the tanks need emptying, and has discovered that the hose which came with a used trailer looks worryingly thin. Or someone with a new trailer and nothing at all, which is the more common situation and the easier one.
How we choose
Completeness first. The failure mode that ruins a first trip is not a slightly inferior hose — it is arriving at the dump station without a fitting. So a complete kit beats a better hose sold bare.
Then wall thickness and fitting design, because those are what actually fail. Then storage, because a 20-foot hose has to live somewhere and a 4-inch bumper will not take it.
We do not test these in a lab and we do not claim to. What informs the picks beyond published specifications is a lodge that hosts RV sites every weekend, which means seeing a lot of hoses in use and a reasonable number of them fail. Full methodology here.
The picks
1. Best for The first sewer hose to own
Camco RhinoFLEX 20-Ft Sewer Hose Kit
The complete first kit: 20 ft in two sections, both fittings, and a clear elbow so you can see when the tank is actually done.
- Specification
- 20 ft supplied as two 10 ft sections
- Specification
- Swivel bayonet fitting at the rig end
- Specification
- Clear 45-degree adapter included in the kit
What it does well
- The kit arrives complete: hose, both fittings and the clear elbow, so nothing is missing at the first dump station
- Two 10 ft sections means you use 10 ft at most sites and 20 ft when you need it, instead of coiling slack
- The clear elbow lets you see when the tank has actually finished, which is the entire job
The real tradeoff
- Bulkier collapsed than a thin-wall hose, and a 4-inch bumper will not take 20 ft of it
- The bayonet fittings need a firm quarter-turn. A lazy connection is how people end up with a mess
How it measures up
These are judgments from published specifications and what we see at the lodge, not laboratory results. How we choose.
- Beginner fit
- Strong — Nothing to buy separately, nothing to work out.
- Durability
- Good — Thicker than the hose bundled with a used trailer.
- Storage
- Adequate — Twenty feet will not fit a 4-inch bumper. Plan for that.
- Value
- Strong — The category default, and deservedly.
Specifications from Camco.
2. Best for Full-season and rougher sites
Camco RhinoEXTREME 20-Ft Sewer Hose Kit
The same kit with a heavier wall. Worth the upgrade if your hose gets dragged across gravel rather than laid on grass.
- Specification
- 20 ft as two 10 ft sections
- Specification
- Heavier wall than the standard kit
- Specification
- Same swivel fittings and clear elbow
What it does well
- A noticeably tougher wall, which matters if the hose gets dragged over gravel rather than laid on grass
- Same fittings as the standard kit, so sections interchange with what you already own
The real tradeoff
- Heavier and stiffer to coil, especially in the cold
- Costs more for a difference you may never need if you camp on grass
How it measures up
These are judgments from published specifications and what we see at the lodge, not laboratory results. How we choose.
- Beginner fit
- Strong — Identical to use.
- Durability
- Strong — The reason to buy it.
- Storage
- Adequate — Slightly bulkier than the standard hose.
- Value
- Good — Pays back over a full season, not a weekend.
Specifications from Camco.
3. Best for A stronger fitting
Valterra Viper 20-Ft Sewer Hose Kit
The alternative worth knowing: the hose is comparable and the fitting is built where these kits usually fail first.
- Specification
- 20 ft kit
- Specification
- Reinforced fitting design
- Specification
- Standard bayonet connection
What it does well
- The fitting design is the part people praise, and the collar is usually what fails first, not the hose
- Directly interchangeable with the common bayonet standard
The real tradeoff
- Less widely stocked, so a mid-trip replacement section is harder to find
- Kit contents vary by listing
How it measures up
These are judgments from published specifications and what we see at the lodge, not laboratory results. How we choose.
- Beginner fit
- Good — Same connection method as everything else.
- Durability
- Strong — Fittings are the strong point.
- Storage
- Adequate — Same bulk problem as any 20 ft hose.
- Value
- Good — Competitive, if you can find it stocked.
Specifications from Valterra.
4. Best for Seeing when the tank is done
Camco RhinoFLEX Clear 45-Degree Sewer Adapter
The clear elbow: the cheapest way to know a black tank is genuinely empty rather than probably empty.
- Specification
- Clear 45-degree elbow
- Specification
- Fits the standard bayonet hose end
- Specification
- Threaded ring for the sewer inlet
What it does well
- You can see when the flow runs clear, which is the only reliable way to know a tank is empty
- The threaded ring keeps the connection in place instead of backing out mid-dump
The real tradeoff
- Clear plastic stains over a season
- Usually already included in the better kits, so check before buying twice
How it measures up
These are judgments from published specifications and what we see at the lodge, not laboratory results. How we choose.
- Beginner fit
- Strong — Screws on, and then it is obvious.
- Durability
- Good — Fine. It stains rather than fails.
- Storage
- Strong — Tiny.
- Value
- Strong — Small money for real information.
Specifications from Camco.
5. Best for Parks that require a sealed connection
Camco Rhino Sewer Hose Seal Donut
A rubber donut that seals the hose into the park's sewer inlet. Many parks require one, and most people find that out on arrival.
- Specification
- Rubber donut seal
- Specification
- Sits in the sewer inlet
- Specification
- Required by many parks
What it does well
- Plenty of parks require a sealed connection and will tell you so after you have set up
- Costs almost nothing and takes no space
The real tradeoff
- Easy to leave behind in the inlet when you pack up
How it measures up
These are judgments from published specifications and what we see at the lodge, not laboratory results. How we choose.
- Beginner fit
- Strong — Drop it in, push the elbow through.
- Durability
- Good — It is a rubber ring.
- Storage
- Strong — No space at all.
- Value
- Strong — Trivial money, and it avoids a conversation.
Specifications from Camco.
6. Best for The obvious thing nobody packs
Heavy-Gauge Disposable Nitrile Gloves (box)
Keep a box in the sewer compartment itself. The gloves that live inside the trailer are the gloves you do not use.
- Specification
- Box of disposable gloves
- Specification
- Nitrile rather than latex
- Specification
- Keep the box in the sewer compartment
What it does well
- The sewer compartment should have its own box, so you never handle the hose bare-handed because the gloves were inside
- Cheap enough that using two pairs is not a decision
The real tradeoff
- Thin gloves tear on bayonet fittings, so buy a heavier gauge than the kitchen box
How it measures up
These are judgments from published specifications and what we see at the lodge, not laboratory results. How we choose.
- Beginner fit
- Strong — Gloves.
- Durability
- Adequate — Buy a heavier gauge than the kitchen box.
- Storage
- Strong — A box.
- Value
- Strong — Almost nothing.
What to look for
Length: 20 feet, in two sections
The temptation is to buy 15 feet because it is cheaper and smaller. Most sites are fine with it. The problem is the site where the sewer connection is at the front of the pad and your outlet is at the back, and there is no partial solution to being three feet short at nine in the evening.
Two 10-foot sections is the format to want. Use one section normally, add the second when you need it, and you are never coiling ten feet of slack hose on the ground where it will hold liquid. The sizing question gets its own page: what size RV sewer hose do I need.
Wall thickness, and when it matters
Thin-wall hose is fine if it lives on grass and gets handled gently. It is not fine if it gets dragged across gravel, stepped on, or stored tightly compressed in a bumper for months.
The thing that fails first, though, is usually not the hose wall. It is the collar where the hose meets the fitting. That is where flexing concentrates, and it is why the fitting design matters as much as the hose grade.
Fittings
What each fitting does
| Fitting | Job | Notes |
|---|---|---|
| Swivel bayonet | Connects to the rig's outlet | Swivel matters. A fixed fitting twists the hose |
| Clear 45-degree elbow | Connects to the park's sewer inlet | Clear so you can see when it runs clean |
| Threaded ring on the elbow | Holds the elbow in the inlet | Stops it backing out mid-dump |
| Rubber donut seal | Seals the elbow into the inlet | Many parks require one |
| Section coupler | Joins two hose lengths | Included on sectioned kits |
Storage, which decides a lot
A 4-inch rear bumper is a traditional sewer hose storage tube, and 20 feet of full-diameter hose will not go in one. Check what you actually have before buying: many trailers have a dedicated sewer compartment, many owners use a plastic tote in the truck bed, and some genuinely have nowhere.
We go through the realistic options, including the bumper question, in sewer hose storage ideas.
Mistakes first-timers make
Skipping the support. This is the single most common thing we see. The hose lies flat on the ground, the tank drains slowly or incompletely, and the owner concludes the hose is faulty. It is not: waste needs a slope to run downhill. A hose support costs very little and fixes the complaint outright.
Not turning the bayonet firmly. A quarter-turn until it seats, and then a tug to confirm. A connection that is merely resting in place is how people acquire the story they tell for years.
Dumping in the wrong order. Black tank first, then gray. The gray water flushes the hose afterwards. Doing it the other way around leaves the hose exactly as unpleasant as you would expect. Full sequence in how to hook up an RV sewer hose.
Emptying the black tank early. Wait until it is around two-thirds full. A tank dumped when it is barely full does not have enough liquid volume to carry solids out, and the residue is what causes every subsequent complaint.
Keeping the gloves inside the trailer. They need to be in the same compartment as the hose. Gloves you have to go and fetch are gloves you do not use.
Questions people actually ask
What length RV sewer hose should I get?
Twenty feet, supplied as two ten-foot sections. Ten feet reaches at most sites, and the second section covers the ones where the connection is at the far end of the pad.
Are all RV sewer hoses the same size?
The diameter is standardized at three inches for the hose and the bayonet fittings, so sections and fittings from different brands generally interchange. Length, wall thickness and fitting quality are what vary.
Do I need a sewer hose support?
Yes, in practice. Waste needs a downhill slope to run properly, and a hose lying flat on the ground drains slowly and incompletely. It is the single most common thing first-timers arrive without.
What is the clear elbow for?
So you can see the flow. When the water running through it turns clear, the tank has actually finished emptying, which is the only reliable way to know. It also stops you guessing on the black tank.
Can I leave the sewer hose connected all the time?
The gray tank can be left open at a full-hookup site if you prefer. The black tank valve should stay closed until you dump, because liquid needs to accumulate to carry solids out. Leaving the black valve open is the most common cause of a clogged tank.
How often should I replace my sewer hose?
When it shows cracking at the collar, a pinhole anywhere, or a fitting that no longer locks positively. Inspect it at the start of each season alongside the rest of your checks.
