The 9 Best Sewer Hose Kits
Updated by · How we research
Nine RV sewer hose kits compared on wall thickness, reach, fittings and storage, from thin vinyl to crush-proof hose. The Camco RhinoFLEX 20-foot kit leads. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki.
The hose wall decides how long a sewer kit lasts: thin vinyl is fine for a few trips a year, while thicker reinforced hose stands up to full-time use and rough sites. Every kit here locks onto the standard RV outlet and comes with a way into campground inlets. This list is for RV and trailer owners replacing a cracked hose.
Editor's Notes
November 1, 2026, by Ezvid Wiki Admin:
The Camco RhinoFLEX now leads the list. Its steel-wire hose holds a bend, the kit comes with every fitting most sites need, and it's built in America at a fair price. The Camco RhinoExtreme RV, Valterra Dominator, Camco Deluxe 39658, Lippert Waste Master and Thetford Titan Premium all stay.
We dropped the Valterra Solution because it's a water-jet drain pump rather than a hose, the Prest-O-Fit Blueline because it has disappeared from stores, and the Camco Revolution Swivel because it's a thinner take on the Deluxe. New picks fill gaps readers asked about: a budget two-hose kit, a single short hose and a boxed kit with its own supports. The deciding evidence was each maker's wall thickness and material, owner reports of cracked ribs and leaky swivels, and a recall search on every brand.

Having a flushable toilet in your RV or camper is a luxury that most people can appreciate, however, at some point it will need to be emptied, and to do so a good quality hose is a necessary piece of equipment as it prevents spillage and drips. Whether you are looking for an upgrade or replacing a broken system, one of these kits should provide you with all the necessary connectors and fittings to complete the task without causing a mess.
In this most recent update, we researched the current market, and our previous selections, and found that no changes are necessary at this time. By and large, these kits are composed of a flexible hose and either universal or specific connectors, which are used to link the waste tank to the emptying facility, therefore, the durability of the hose and the watertight seal of the connectors are of primary importance. Beyond that, the extendable length of the hose and how compactly it stores away will likely be the next major consideration. The Camco Revolution Swivel, for example, has two hoses, providing either a 10- or 20-foot set up. It compresses down quite nicely too, however, its outer diameter and the width of connectors make it a little too big to fit into many bumper storage boxes. The Camco Deluxe 39658, on the other hand, compresses down to a mere 24 inches, making it a good choice for smaller RVs and frequent travelers. The Camco RhinoExtreme RV is a very durable option that is reinforced with steel wire, making it resistant to crushing. It comes with a transparent elbow, so you can easily see when the tank is empty, and a 4-in-1 dump station fitting for a variety of different diameter connectors. The Prest-O-Fit Blueline is notable as it uses push-fit connectors that stay in place using friction. This may sound like an accident waiting to happen, but well-designed and well-made parts make it highly resistant to leaks, and it can certainly save time when assembling the system.

There's no way to overstate the importance of a reliable sewer line, as anyone who's even been splashed with a few day's worth of waste can definitely tell you. In assembling a list of these hose kits, we wanted to make sure that all connection points were as solid as possible, and that the material construction of the hoses themselves were as durable as possible. That's why we had to send the Valterra Viper packing, as its hose proved to be a little too thin. Early applications weren't the issue here so much as long term use, as small tears in the sides of the hose could easily result in leaks. And even small leaks when dealing with sewage are a big deal.
In reorganizing the list to reflect our continued evaluation of these products, the Lippert Management System rose to the top thanks to an excellent valve system that's both easy to use and reliable. It wont slip open on you from small bumps and jostles, and when you close it, it closes securely. And don't let the narrow diameter of the Valterra system at number four fool you; it's designed to pulverize solid waste as it drains from your tank, so as long as your kids don't accidentally flush any toy cars down the toilet, it will work rather well.
Special Honors
Valterra Slunky Hose Support Valterra's Slunky is a folding plastic cradle that holds a sewer hose off the ground at a steady downhill slope, so waste doesn't pool in dips. It collapses like an accordion for storage and comes in several lengths to match a 10 to 25-foot hose. RV dealers and hardware stores carry it. valterra.com
Wall Thickness Is What You Pay For
It's light and packs down tiny, but it can tear on sharp gravel and get brittle in the sun.
Sewer hose walls are measured in mils, thousandths of an inch, and that number tracks durability more than anything else on the box. Budget kits use vinyl around 15 to 18 mils. It's light and packs down tiny, but it can tear on sharp gravel and get brittle in the sun. Heavier kits run about 23 to 24 mils.
Camco's RhinoFLEX kit uses 23-mil polyolefin wrapped around steel wire, which lets the hose hold whatever bend or length you give it. The RhinoEXTREME moves to a 24-mil rubbery plastic (thermoplastic elastomer) over a reinforced core. Thetford's Titan uses the same kind of rubbery plastic, which shrugs off being stepped on but doesn't compress much for storage, a trade-off Getaway Couple points out.
If you camp a few weekends a year, vinyl will do. If you live in the RV or park on rough sites, the thicker wall pays for itself in hoses you don't have to replace.
Length, Fittings And Inlets
Most kits are 20 feet, sold as two 10-foot hoses you can use alone or join. That reaches most campground inlets, but plenty of RVers carry a 10-foot extension for the odd far-off pipe. A 15-foot single hose costs less and has one fewer joint, but it only suits close inlets.
The RV end almost always uses a bayonet fitting: line up the lugs, push and twist. Swivel or rotating fittings keep the hose from kinking as you lock it on. At the ground end, a clear elbow lets you see when the tank is empty, and a stepped adapter fits a plain 3-inch pipe or 3, 3.5 or 4-inch threaded inlets.
Lippert's Waste Master works differently. A cam-lock fitting is mounted on the RV's outlet once, and the smooth-walled hose clips onto it and stretches out from a short coil. Lippert's waste-management range sells extensions and replacement fittings for it. Before you buy any kit, check how long it is when compressed if you plan to store it in a 4-inch bumper tube: you may need to remove the adapter first.
Dumping Cleanly And Safely
Close both tank valves before connecting anything, then attach the hose to the RV first and the inlet second. Don't stretch the hose tight, or it can pop off when the waste surges. Dump the black tank first and the gray tank second, so the soapy gray water rinses the hose, as CamperFAQs' dump station guide lays out. Wear disposable gloves, and rinse the hose before you cap it.
A hose support, such as Camco's Sidewinder, keeps a steady downhill slope so nothing sits in the low spots. Keep the sewer kit, and any hose you use to flush the black tank, well away from your drinking-water hose: store them in separate bins and never swap them.
Empty tanks only into a campground sewer inlet or a dump station. We found no recalls for any of the brands here in the U.S. Consumer Product Safety Commission's recall database as of this update.
How we researched this
We compared 16 sewer hose kits and related drain gear, read the makers' specs for wall thickness, material, fittings and warranty on the nine finalists, analyzed owner feedback for patterns of cracking, leaks and storage fit, and checked every brand against the U.S. Consumer Product Safety Commission's recall database. We found no independent lab tests of sewer hoses.

Frequently asked questions
What length sewer hose do I need?
A 20-foot kit, usually two 10-foot hoses, reaches the inlet at most campsites. Carry a 10-foot extension for sites where the pipe is farther away. A 15-foot single hose is enough if you mostly use dump stations or sites with a close inlet.
What is the difference between the Camco RhinoFLEX and RhinoEXTREME?
The RhinoFLEX uses a 23-mil polyolefin wall wrapped around steel wire. The RhinoEXTREME uses a 24-mil rubbery plastic over a reinforced core with a tougher outer rib. The RhinoEXTREME costs more and packs down longer, so it suits full-timers and rough sites.
How do I connect an RV sewer hose?
With the tank valves closed, lock the bayonet end onto the RV outlet with a push and a twist. Then fit the elbow and adapter into the campground inlet. Open the black tank valve first, then the gray.
How long does a sewer hose last?
It depends on the wall and how it's treated. Thin vinyl can split within a season of hard use, while heavier hoses often last years. Sun, sharp gravel and dragging do the most damage, so store the hose out of the sun and lift it rather than pull it.
Can I store my sewer hose with my drinking-water hose?
No. Keep waste hoses and fittings in their own bin, away from the drinking-water hose, and use a separate hose for flushing the black tank.
