10 min read6 products evaluated
Buying a sewer hose starts with one question: do you need a complete kit or only an extension? A complete kit such as the Camco RhinoFLEX 20ft includes two hose sections, a clear elbow with an adapter and storage caps, while an extension only lengthens a hose you already own.
This hub explains the choice between kits and extensions, then ranks six picks by stated material thickness, cold flexibility, collapsed length and connection style. Gravity sewer hoses are not made for pressurized macerator discharge, and a quoted length may be combined sections, so read how each listing counts feet.

How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- Kit or extension
- We separated complete kits from extensions, since one includes the elbow and caps and the other does not.
- Wall thickness
- We compared stated mil ratings and reinforcement, treating them as manufacturer claims.
- Length counting
- We checked whether quoted feet are one piece or joined sections.
- Packed size
- We compared collapsed lengths and bumper fit.
- Connection and cold rating
- We noted fitting style, adapters and any stated temperature range.
What Matters Before You Choose an RV Sewer Hose
Key buying criteria so you get the right fit the first time.
Wall thickness in mils
A mil is one thousandth of an inch, and a thicker wall resists punctures and abrasion from dragging on gravel. A thin hose develops pinholes sooner. Compare the stated mil figure, such as 18, 23 or 24, and see whether a steel wire or vinyl layer is named.
Kit contents
A complete kit includes hose sections, a clear elbow, an adapter and caps, while an extension includes none of those. Buying an extension first leaves you without a way to connect. Read the contents list for caps and the adapter.
Length and sections
A 20 foot kit may be two 10 foot hoses joined, which adds a connection that can leak. Total reach also shrinks around bends. Check whether the length is one piece and add margin for your dump distance.
Collapsed length
A hose must fit your bumper or storage tube, and 10 feet can pack to 39 or 45 inches depending on the design. A bundle that is too long will not fit. Compare the stated compressed length against your storage space.
Fitting and adapter
Bayonet and lug ends must match your outlet, and a 4-in-1 adapter covers 3 inch slip and 3, 3.5 and 4 inch threaded dump inlets. A mismatch means a leak or a second purchase. Look for named inlet sizes.
Cold flexibility and gravity use
A stiff hose will not lie flat in freezing weather, and these are gravity hoses, not macerator discharge hoses. Pressurized use can burst a gravity hose. Look for a stated temperature range and read the intended use.

| Dump 15 to 20 ft away | Camco RhinoFLEX 20ft | Two 10 ft sections with steel wire. |
| Budget 20 ft reach | DUMPMAN 20ft | Same kit contents at a lower price. |
| Need a few extra feet | Camco RhinoFLEX 5ft | 5 ft thick-wall add-on. |
| Need 10 more feet | Camco Deluxe 10ft | 10 ft extension that packs small. |

By Budget
| Budget | Recommended pick |
|---|---|
| $20 to $30 | Camco Deluxe 10ft or Camco RhinoFLEX 5ft |
| $30 to $40 | Valterra Dominator 5ft or DUMPMAN 15ft |
| $40 to $70 | DUMPMAN 20ft or Camco RhinoFLEX 20ft |
Complete Kit vs Extension
- Complete kit
- The Camco RhinoFLEX 20ft, DUMPMAN 20ft and DUMPMAN 15ft include the elbow, adapter and caps. They are the right start if you own no hose.
- Extension
- The Camco Deluxe 10ft, Camco RhinoFLEX 5ft and Valterra Dominator 5ft only add length to a hose you already have. They are cheaper but need an existing bayonet hose.
Most buyers without a hose should start with the Camco RhinoFLEX 20ft or DUMPMAN 20ft and add an extension only when the dump is far.
By Climate and Storage
| Priority | Recommended pick |
|---|---|
| Freezing weather | Valterra Dominator 5ft |
| Tight bumper tube | Camco Deluxe 10ft |
| Smallest packed size | Valterra Dominator 5ft |
| Steel wire reinforcement | Camco RhinoFLEX 5ft |
For Weekend Campers with a Small Bumper Specifically
- Look for
- A collapsed length that fits your storage tube, a complete kit with an elbow and caps and a hose that is not too long, as the Camco RhinoFLEX 20ft listing shows.
- In this comparison
- The Camco RhinoFLEX 20ft packs each section to about 39 inches, and the Camco Deluxe 10ft stores in a 4 inch square bumper.
When to Spend More
- Spend more if
- Spend more on the Camco RhinoFLEX 20ft or Valterra Dominator 5ft if you want steel wire reinforcement, a shorter packed length or a stated cold rating.
- Save if
- Save with the DUMPMAN 15ft or DUMPMAN 20ft if you dump at nearby sites and want a complete kit at the lowest price.
Before You Bring One Home
What length sewer hose do I need?
Measure from your outlet to the dump inlet and add a few feet for bends. A 15 foot hose like the DUMPMAN 15ft suits close dumps. Longer runs call for a 20 foot kit or an extension.
Can I use a sewer hose with a macerator pump?
Not unless the listing says so. These are gravity hoses, and pressure from a macerator can burst them. Use a hose rated for pump discharge.
Is the Camco RhinoFLEX 20ft worth more than the DUMPMAN 20ft?
If you want steel wire reinforcement and a shorter packed section, yes. The DUMPMAN 20ft gives the same kit contents for less.
How do I connect two hoses or an extension?
Twist the bayonet ends together until they lock and check the seal. The Camco RhinoFLEX 5ft works with any bayonet-fitting hose. Support the run so waste flows downhill.
How should I store a sewer hose?
Drain, rinse and dry it, then cap both ends and store it in a bumper tube or sealed bin. Keep it away from living space. Inspect for pinholes each season.
