You can save a buck or two on some RV accessories, but not all. When it’s time to do one of everyone’s least favorite parts of RVing (emptying your tanks), you want the best. Not all RV sewer hoses are created equal, so today, we wanted to share with you the five best RV sewer hoses on the market. Let’s dive in!

What Is an RV Sewer Hose?

RV sewer hoses connect to an RV’s holding tank dump connection outlet to allow you to empty black and gray water tanks. Hoses are lightweight and made from thin, durable plastic for easy storage.

Are RV Sewer Hoses Universal?

Standard RV sewer hoses are 3 inches in diameter with lugs and fittings on opposing ends. RV sewer connections are generally universal, but having adapters on hand can keep you prepared for any dump station scenario. There’s a huge variety of situations at both dump stations and full hook-up campsites. Height, angle, distance from the RV, and pipe sizes frequently differ from one to the next, so it doesn’t hurt to be prepared.

Are All RV Sewer Hoses the Same?

Not all sewer hoses are equal. Quality matters!
A sewer hose is no place to skimp! A good quality hose is a worthwhile investment.

RV sewer hoses come in varying lengths, but thickness is the primary factor that sets one apart from the next. A hose’s thickness and price are often directly related. More expensive hoses sometimes offer smoother interiors for optimized flow and ease of cleaning.

Manufacturers measure sewer hoses in “mils,” which can be confusing if you’re not familiar with this unit of measure. An article from Global Plastic Sheeting states, “A mil is a measurement that equals one-thousandth of an inch or 0.001 inches. One mil equals 0.0254 mm (millimeter).”

Continue reading their guide to plastic sheeting measurements to understand how to measure your hose.

How Long Should an RV Sewer Hose Be?

The most common lengths for RV sewer hoses are typically between 10 and 20 feet. You’ll want to make sure you have enough hose to reach the dump station, or campsite sewer hook-up, which is simple if you consistently hook-up or dump at the same location.

Adapters are important to have on hand, to ensure that you’ll be able to make a good fit between your hose and the dump station. Shown is a 4-in-1 dump station fitting.

If dumping, or hooking up, at different locations on a regular basis, you’ll probably want to skew toward a longer hose, like the 20-foot hose we use as full-timers. The location of your RV’s sewer outlet, and the location of the dump station, or campsite sewer hook-up, are important. Some sites have sewer hook-ups that are very far back. This requires a longer hose, especially if your RV’s water compartment is in the middle of your rig.

What to Look for in an RV Sewer Hose?

All RV sewer hoses have the same purpose, but they’re not all created equal. We want to share with you some essential things to consider when purchasing an RV sewer hose.

Ease of Use

Emptying your RV tanks should never be taken lightly. You also don’t want your equipment to be overly complicated. When selecting a sewer hose, look for a product that will quickly and efficiently transfer your RV waste into the dump station.

Portability/Storage

When you’re not using your sewer hose, you want it out of sight and out of mind. Thinner hoses generally take up less room than thicker hoses, but they can also be more prone to being damaged/punctured.

No matter what length or thickness you select for your hoses, have a storage plan. Many RVs come with storage tubes mounted under the rig or a designated space inside the bumper. Our RV has a hose storage sleeve built into the side of the bodywork. It’s a great feature, but does require that at least one end of the hose be left free of any type of permanently-attached adapter, so it limits our choices.

Ease of Cleaning

It could probably go unsaid, but the last thing you want is raw sewage sitting in your hose for extended periods. Flushing water through your tanks and hoses is the best way to keep them clean. For optimal sanitation and ease of cleaning, you can connect external attachments to help.

Various Attachments

You’ll want to have some attachments to handle potential scenarios you might encounter at dump stations and campsite hook-ups. A clear elbow, for example, lets you keep an eye on the flow of waste when emptying your tanks.

A clear elbow allows you to see when clear water is running through the hose, indicating that the rinsing is complete.

At some point, you’ll likely encounter a sewer connection that’s very far from your RV’s sewer outlet. So coming prepared with an additional hose is a great purchase as well, along with a connector to join them. Other attachments that are important to have are a rubber doughnut for a secure fit into the drain and a weight to keep your hose connected to the drain, if it’s not threaded.

  1. Thanks for showing us some quality sewer hose options. It pleases me to know that I’m already using one of your choices (#3).

    When looking to replace a leaking connector and buy new hose I had only two prime needs: it had to be a better quality reputable hose that does not kink easily and it MUST slide easily into the storage tube of my coach.

    That meant that one could have a small connector but the other end had to be just hose. My storage tube has a 90° angle just inside the access door and tilts slightly downward toward the drive tires. I’ve never had any binding issues with the Camco hose.

  2. Thanks, good recommendations, particularly on quality hose. There’s a surprising amount of pressure when dumping, and having a blowout is not a place I want to be. Personally I find it easier to carry two 10’ than a 20’. Trying to wind a 20 footer to a dump station that’s only 5 or so feet from the coach can be challenging. Our small coach doesn’t have a storage tube, so two 10 footers that collapse like the Camco work well for me, and collapse smaller than the 20’ can. The 10’ collapsing to 39” is small enough for me to cap them then put them in a plastic box for storage.
