Best RV Sewer Hoses Reviews & Recommendations
How We Selected RV Sewer Hoses
The Drive’s editors eat, sleep, and breathe products that help you with your life as an enthusiast. No, we don’t eat or breathe RV sewer hoses, to be exact, but we have spent more time than we’d like to admit reading reviews, researching products, and cross-checking specs. You can trust that we’ve done our homework to find products that you can feel good about buying and using.
When it comes to RV sewer hoses, we looked at a few main characteristics to make our choices. The hose has to be fairly easy to use, as in, it can’t take three people to connect and drain your RV’s tanks every time. It needs to be durable and last at least as long as the manufacturer claims that it will. Finally, we looked for products with clever designs that make the sometimes unpleasant job of emptying the tanks quicker and less annoying.
Our product selections, rankings, and awards for this story are based on research. While we haven’t conducted real-world testing on all of these products yet, we’ve looked at consumer testimonials and data, tutorials, and general discussions on social media and in forums. We also consider price and specification in the context of the segment. And, of course, we rely on our institutional knowledge of the automotive landscape to weed out weak products.
Buying Guide/What to Look For
There are so many sewer hoses on the market that it can be hard to tell which one offers the features and functionality you need.
What to Consider When Buying RV Sewer Hoses
Fit and Design
You’ll notice that, with the exception of one hose, all of the products we listed here use a common bayonet connection. This is important because it means that all but one can be used out of the box without modification or additional work from you. It’s also important to study the design of the hose to ensure that it will fit in the storage space you need and that it will fit your RV’s connection point.
Ease of Use
Some hoses feature special linings or coatings that prevent the buildup of debris and make the drainage process quicker. These hoses may or may not be as collapsible or as easy to store as others, so it’s important to understand the features of each.
You won’t be able to find a hose to last until the end of time. It’s just not possible. However, you can find a hose that suits your needs and can stand up to a little abuse. In general, a hose that can resist crushing is a good idea. Since the hose will be laying on the ground, sometimes in confined, high-traffic areas, it’s a good idea to find one that won’t smash to pieces if stepped on.
It’s true that you get what you pay for. But focusing on price alone can lead to some heartbreak, and in the case of sewer hoses, big messes. Look for a hose that offers a good balance of budget pricing and durability.
RV Sewer Hose Tips and Tricks
As with something you do for decades upon decades, you pick up a few tips and tricks along the way in terms of selecting the right product, and/or using it. That’s the case with us and RV sewer hoses. To help you bridge the information gap, here’s a selection of what we’ve learned along the way.
- It’s better to buy a longer hose than you need to ensure you’ll be able to reach the dump station.
- Be careful to look for a durable hose that is also flexible enough to be stored properly.
- Heavy-duty fittings and seals are great, but if they give you arthritis to use, you’re going to tire of using the hose.
- If your RV has a tight space around the drain or oddly shaped body work around the drain area, you’ll want to make sure that the hose you choose will fit.
Q: How long should my RV sewer hose be?
It’s better to have more than you need than not enough, but in general, it’s best to aim for between 10 and 20 feet of hose. Many hose manufacturers sell units that come in two pieces, so you can use one or both, depending on your needs.
Q: Why does my RV smell bad after I drain the tank?
Your RV may have a less-than-fresh smell after draining because debris and other gunk can build up around the valves and pipes that carry waste out of the vehicle. It’s a good idea to clean as much as possible and to clean your sink and shower drains at the same time.
Q: Can I use bleach to clean my black water tank?
It’s best to avoid using bleach or other caustic cleaning agents that can damage seals or cause issues with internal plumbing. Find a cleaning product that advertises as being safe for RV tank cleaning.
Q: How often should I replace my RV sewer hose?
In general, you’ll want to look at replacing your RV sewer hose every 32-36 months, depending on how often and heavily it has been used. If you notice damage, cracking, or leaks, it’s a good idea to go ahead and replace the hose as soon as possible.
Q: Where do I store my RV sewer hose?
Most RVs come with a storage container near the rear bumper. If yours has such a storage space, measure it before buying a hose to make sure that the hose you select will fit.
There are dozens of RV sewer hoses, many of which will serve your needs just fine. Check out our best overall pick, the Lippert Waste Master 20’ Sewer Hose, which is highly durable and has a unique design. For a better deal, consider the Thetford Titan 15-foot Premium RV Sewer Hose.
