The Best RV Sewer Hoses Option


RVing is a wonderful way to commune with the great outdoors without giving up many of the comforts of home, including hot showers and flushable toilets. As wonderful as those amenities are, they come with a price. One unlucky camper must take on the job of dumping all that wastewater at the campground dump station when the camping trip is over. While there is no RV sewer hose on the planet that can make this dirty job enjoyable, there are models that make it more tolerable.

These quality RV sewer hoses come with high-quality fittings that make tight connections so the person doing the dumping doesn’t have to deal with nasty sewage spills or endure foul odors. They’re versatile, too. A good RV waste hose can extend up to 20 feet in length to bridge longer distances between the RV and sewer drain and then break down to less than 5 feet for easy storage.

Since RV hoses come in various lengths and material types, choosing the right one can be a confusing process. This guide will plumb the depths of RV sewer hoses to identify the crucial factors one should consider when shopping for an RV drain hose while reviewing some of the top models on the market.

What to Consider When Choosing the Best RV Sewer Hoses

While choosing an RV sewer hose that’s long enough to make the connection between an RV and sewer drain is perhaps the most crucial element when shopping for a sewer hose, other factors are also important, including thickness, fitting types, and flexibility. Ahead, learn more about these and other critical attributes of RV sewer hoses.


An RV drain hose must be able to reach from the RV’s main drain to the drain hole at the dump station. Most newer RVs have drainpipes located conveniently on the side of the camper, making it easy to pull close to the dump station’s drain. Other RVs may have their drain in the middle of the RV’s rear end, which requires a longer hose. A 15-foot-long hose will suffice for most RVs. Consider purchasing a 20-foot hose or a hose extension if the RV’s drain is located in the center.


An RV hose must be able to endure being dragged around on the ground and repeatedly stretched for use and then compacted for storage. With this in mind, the hose should be constructed of a material that will hold up to this abuse. RV hoses vary in thickness from as little as 15 mils to as much as 26 mils. While a 26-mil hose may be more expensive and a little bulkier than a hose that uses thinner plastic, it will last longer than a thinner 15-mil hose and provide more assurance that it won’t break open while in use.


Most RV drainpipes feature a flexible design, allowing the drain line to bend at sharp angles without kinking as it travels from the RV drain to the dump station drain. A ridged accordion design allows the hose to expand or contract to suit different distances, allowing the user to extend it to reach longer distances or contract it to eliminate extra slack that could impede the flow of wastewater from the RV’s tanks to the drain.

Ease of Use

Most RV hoses use an accordion design and bayonet-style connection that make them easy to set up and break down. The accordion-style drainpipe can be extended to the required length to reach from drainpipe to sewer drain when in use or contracted down to a compact size for easy storage inside the RV’s rear bumper. The twist-and-lock fitting connections allow the user to attach and detach the hose from the drainpipe without having to use any special tools. And most sewer adapters are designed to fit multiple types of drainpipe, making it easy to simply drop the end into the pipe to make a connection to the dump station. Some sewer adapters even have handles that make the fitting easier to maneuver and shut-off valves that allow the user to quickly cut off the flow of wastewater should a problem occur.


An RV sewer hose’s accordion design not only makes it flexible and adjustable to suit different distances, but it also allows the user to compress it down to a smaller size for storage. Every 10 feet of sewer hose compresses to between 3 and 4 feet depending on the hose. This compact size makes it easier to fit the hose into the RV bumper, which is a common storage place for RV hoses. All sewer hoses include drip caps, which allow the user to seal off the ends of the hose, preventing moisture or odors from leaking out while in transit.

Fittings and Accessories

RV sewer hoses connect to the RV drainpipe and dump station sewer drain via fittings that attach to both ends of the hose. The fitting that attaches to the RV drain uses a twist-and-lock bayonet hook fitting that consists of four long hooklike prongs that latch onto the drainpipe, creating a tight fit that prevents leaks and won’t blow off. The other end of the hose attaches to a sewer outlet adapter either through a threaded screw-on connection or a bayonet-style connection.

The sewer outlet adapter is L-shaped and has a tapered end that fits into the dump station drainpipe. Manufacturers commonly rate these adapters as 4-in-1 or 5-in-1. This number refers to the types of dump station drains the adapter will work with. A 4-in-1 adapter, for example, fits into 3-inch slip drainpipes or 3-inch, 3½-inch, and 4-inch threaded drainpipes.

This sewer fitting, commonly referred to as an elbow adapter, should consist of clear plastic so the user can see when the tanks are empty or, if flushing the black tank, when the water passing through the hose runs clear. Some RV drain hose kits come with extensions, which are convenient for bridging longer gaps between the RV’s main drain and the dump station’s drainpipe.

RV sewer hoses also come with drip caps, which cover the hose ends to prevent odors and moisture from leaking out while the hose is in storage.

Tank Outlet Size

The standard drainpipe size for most RVs is 3 inches. However, older RVs sometimes have different drainpipe sizes. Since sewer hoses are designed to fit 3-inch drainpipes, an adapter may be needed for the hose to work with an older RV with a drain size other than 3 inches.

Our Top Picks

The list below takes all the above considerations into account to narrow the field to some of the best RV sewer hoses on the market. It includes hoses that are durable, easy to use, and versatile so RVers can enjoy the great outdoors with peace of mind.

Best Overall

The Best RV Sewer Hoses Option: Valterra Viper 20-Foot RV Sewer Hose Kit

This RV hose’s versatility coupled with its durable construction makes it one of the best all-around options on the market. The hose consists of two 10-foot sewer hoses that allow the user to make a shorter connection without the extra length of a 15-foot or 20-foot hose to contend with or a longer connection by simply joining the two hoses via a four-prong bayonet hook connection. Each hose collapses to just 50 inches for storage.

The elbow connection is made from translucent plastic, making it easy to see when the tanks are empty, and it fits six different sewer drain types. With its tight seal, the user doesn’t have to endure foul smells coming up from the dump station drain while waiting for the tanks to empty. A 135-mil outer beading protects it from being crushed, so this is also one of the more durable sewer hoses on the market.

Best Bang for the Buck

The Best RV Sewer Hoses Option: Camco RhinoFLEX 15' Sewer Hose Kit

Those looking to pay less for a sewer hose kit should consider this model from Camco. It costs significantly less than other RV sewer hoses but is still well constructed. It features a RhinoFlex sewer hose that extends up to 15 feet and compresses down to just 56 inches for easy storage. The elbow adapter is versatile, thanks to its ability to fit 3-inch slip drains or 3-inch, 3½-inch, and 4-inch threaded pipes. It’s also translucent, allowing the user to see when the tanks are empty.

A bayonet end on the RV side of the hose includes four prongs versus three, allowing it to achieve a tight fit to the RV drainpipe. And, at 23 mils thick and reinforced with steel wire, this hose is as durable as other higher-priced models. At 15 feet long, this sewer hose is best suited to RVs with drains located on the side.

Best Upgrade

The Best RV Sewer Hoses Option: Lippert 359724 Waste Master 20' RV Sewer Hose

For those who spend a lot of time in their RV or who simply want to leave nothing to chance when it comes to dumping waste, the Waste Master from Lippert is the Cadillac of RV sewer hoses. The most noticeable difference between the Waste Master and other RV sewer hoses is its connection. It uses a CAM lock connector in place of a bayonet-style connector. The CAM lock connector creates a tight connection that won’t leak or blow off the drainpipe while in use.

Unlike most sewer hoses that have a ridged interior, the Waste Master’s interior is smooth, reducing the risk of clogs. It also has a cone-shaped rubber gasket that will fit most any dump station sewage inlet and a shutoff at the elbow for flow control should the dump station suddenly overflow. While these features make the 20-foot Waste Master one of the top sewer hoses one can buy, it’s also one of the most expensive.

Product Specs

  • Length: 20 feet (5 feet, 6 inches compressed)
  • Weight: 10 pounds
  • Thickness: N/A


  • Integrated shut-off valve
  • Smooth interior
  • High-end CAM lock connector
  • Conical rubber sewer fitting


  • Expensive

Best Durable

The Best RV Sewer Hoses Option: TITAN 17853 15-Foot Premium RV Sewer Hose Kit

This 15-foot RV waste hose from Titan is so tough that it will return to its original shape even after being run over by a car. This durability, which sets it apart from other sewer hoses, is due to its use of a thermoplastic elastomer that makes it not only virtually uncrushable but also very resistant to punctures or abrasions.

Similar to other sewer hoses, Titan uses a bayonet-style connection to attach to the RV’s drainpipe. The elbow sewer adapter is capable of fitting into five different types of sewer drains and is equipped with a long handle that makes it easy to maneuver while staying away from the yucky stuff. The elbow does use white opaque plastic as opposed to the clear plastic found in most sewer hose kits. Though a minor difference, it does make it more difficult to monitor the wastewater as it passes through the adapter.

Product Specs

  • Length: 15 feet (5 feet, 6 inches compressed)
  • Weight: 4.5 pounds
  • Thickness: 26 mil


  • Durable, uncrushable hose
  • Scuff and puncture resistant
  • 5-in-1 elbow adapter


  • The opaque adapter makes it difficult to monitor wastewater flow

Best Dual

The Best RV Sewer Hoses Option: Camco 39667 Revolution 20' Sewer Hose Kit

With its “Wye” connector fitting, this sewer hose kit connects two hoses to one adapter, enabling it to simultaneously service two RV drainpipes at once. This makes it ideal for larger RVs with more than one drainpipe. Camco’s Y-shaped Wye connector attaches to two hoses and the 4-in-1 adapter via bayonet-style fittings, sending wastewater from two separate drainpipes to the sewer drain. All three connections swivel 360 degrees, making it easy to maneuver the hoses into position. The clear adapter and white Y-connector allows the user to see when each tank is empty.

The Wye connector can also be removed, allowing the kit to function as a standard single sewer hose. Each section of vinyl hose is 10 feet and compresses down to about 24 inches for storage, both in a standard 4-inch-square bumper.

Product Specs

  • Length: 2 by 10 feet (2 feet compressed)
  • Weight: 6 pounds
  • Thickness: 15 mil


  • Can serve two drainpipes at once
  • Compacts to small size for easy storage
  • Clear 4-in-1 adapter


  • Vinyl construction is thinner than other materials

How We Chose the Best RV Sewer Hoses

We used several criteria when making our choices for our list of the top RV waste hoses. Ease of use and versatility were key. We chose hoses that the user could set up and break down easily, minimizing the time spent at the dump station. And since no two dump stations are alike, we favored models that could capably reach distances both short and long and work with a variety of sewer drain types. To make our list, the kit’s fittings needed to be easy to attach and detach without the need for special tools. They also needed to have translucent elbow adapters that would allow the user to easily monitor the flow of wastewater. Since sewer hoses tend to take a beating, we also chose thicker hoses made from durable materials. Portability is also crucial, so we only chose hoses that would condense to a small enough size to be easily stored.


If you’re wondering how long your sewer hose should be or if any sewer hose will work with your rig, then read on for answers to these and other commonly asked questions about RV sewer hoses.

Q. How long should an RV sewer hose be?

That depends on the positioning of the RV’s drainpipe. For trailers or motor homes with drainpipes on the side of the RV, 15 feet should suffice. For those with drainpipes at the center of the rear of the RV, go with a longer 20-foot hose.

Q. Are RV sewer hoses universal?

For the most part, yes. RV sewer hoses are designed to fit standard 3-inch RV drainpipes, which covers all newer RVs and motor homes. Older RVs may use a different-size drainpipe, which requires an adapter to work with a 3-inch RV waste hose.

Q. How do I clean an RV sewer hose?

Most RV dump stations are equipped with a freshwater spigot. Attach a hose to this spigot and use it to run fresh water through the hose to flush it out. As a rule of thumb, always dump your black water tank before dumping your gray water tanks. By doing this, you can rinse the hose with soapy gray water once the black water tank is empty.

Q. How often should I replace my RV sewer hose?

Replace an RV sewer hose about every 3 years to ensure it doesn’t break or puncture while in use. Full-time RVers should replace them every 2 years.

Q. Can I hook two RV sewer hoses together?

Yes. In fact, some kits are designed to work this way. Just make sure the two hoses connect using a bayonet-style fitting to ensure they do not leak or blow off while in use.

Q. What size is a standard RV sewer hose?

A standard RV sewer hose is 3 inches in diameter.
