What to look for in a sewer hose

Finding a sewer hose could be as easy as walking into your local RV supply store and just picking one out. That’s great, but here are a few suggestions on what to look for. You want the best price but also good quality so what you get is durable and you don’t have to worry about leaks.

Consider that RV sewer hoses are designed to do the same thing. Dump your waste. They connect to the drainpipe of your vehicle to drain at a dump station or full hookups at your site. They can vary in terms of thickness, damage resistance, flexibility, fittings, the ability to see when drainage has stopped, ease of storage, and price.

1. Fitting type

RV fittings are used to create a seal between your sewer hose and the dumping receptacle. They come in a variety of forms to help drain your tanks.

Most RV sewer hoses use bayonet fittings. These use small pins, which slide into L-shaped slots on the receptor. They work well in preventing leaks. A cam fitting goes a step further and makes leaks almost impossible.

There is also a connection called a slip fitting. This type slips over the sewer outlet and uses a clamp to lock on. They are used very rarely and are likely to leak and slip off.

Threaded fittings are also common and simply twist on and off.

2. Length

The length of your sewer hose should usually be between 10 and 20 feet. You want to make sure you have enough length to hook up at your RV site, which can differ if you camp at different places.

3. Flexibility

Make sure that your sewer hose is flexible enough to bend and reach your sewer connection. It should not be too rigid. Look for a thick hose that can bend back on itself without collapsing.

In your RV travels, you will experience sewer connections that are in some weird spots. Your sewer hose should be flexible enough to accommodate just about any situation.

4. Thickness

The thickness of your sewer hose will determine its durability. A thin hose will likely develop leaks quicker than a thicker hose and will have to be replaced more often. Sewer hoses will have to be replaced eventually. Obviously, the less often they need to be replaced, the more money you will save.

5. Cost

You get what you pay for clearly applies to sewer hoses and their fittings. Going cheap will likely cause leakage problems sooner rather than later. Choose a medium-priced hose that will have some durability. Most decent hoses will cost around $50, depending on the length, etc.

RV sewer hose accessories

Not only do you need a great sewer hose kit but also several accessories to make your RV black water dump the quickest and cleanest it can be.

1. Sewer hose supports

You really can’t let your sewer hose run along the ground between your RV and sewer hookup. Your hose can get beat up or punctured if it’s on the ground. Most definitely you don’t want to trip over it in the dark. However, many RV parks are also requiring that you have sewer hose supports, so this is just a must-have part of your setup.

Sewer hose supports allow you to create an easier flow to flush out wastewater. Most importantly, supports keep your hose off the ground, but they also provide a steady slope for easy draining. Supports should be as least as long as your hose.

2. Elbow fittings

Elbow fittings provide an angled connection from your hose to the inlet. 

3. Hose couplers

These fittings are used to connect two different sewer hoses.

4. Y-shaped fittings

These let you connect two different tanks to a single hose or multiple hoses to a single inlet.

What do I do if your sewer hose fails

If you are at a campground and you get a leak in your sewer hose, you can use garden lime or Clorox to help kill the bacteria.

Be sure and let the office know what happened. I’m sure you are not the first to have a spill and they should know what to do. Offer to pay a professional for any cleanup that might be needed. For the sake of any pets, children, or others who might encounter the affected area, please don’t leave without making sure the mess is cleaned up.

Key takeaways

No matter what, RV sewer hose fittings are something everyone needs, but it’s something that isn’t usually discussed in general conversation.

For the safety and well-being of your family, pets, and nearby campers, this also isn’t a piece of gear that you want to try to save money. Purchase hoses with fittings that will prevent leaks, and always make sure you have a spare hose and fittings available if you have a crushed hose or broken equipment, or if your fittings develop a leak.

Like any equipment you use to RV, make sure you always make an effort to maintain and replace your fittings as needed so you can head out to your next adventure with confidence.

5 thoughts on “What Are The Best RV Sewer Hose Fittings?”

  1. In 2010 we bought our first and only motorhome.; An experienced friend suggested the Valterrea Sewer Solution. Have used now for 14 seasons. No stinky slinky to manhandle, flush and dump. Much easier to store, and hose extensions are available so you can pump waste to a distant septic hole. Great product.

  2. We combine plastic gutters with Sewer Hose supports to suspend the gutters over uneven ground and hoses. We cut 8′ sections in half to create a fit to order channel that holds the house. Our T/T has two drain fittings, one forward for the kitchen grey water and one after that combines grey and black water. The camp sewer fittings are often behind the camper creating the need for 25′ to 30′ of hose. The gutters allow us to suspend the hoses with the proper down slope in a straight line with just a few hose supports holding up the gutters where they overlap. The hoses terminate a Y fitting at the camp sewer connection. My only error was to buy white gutters instead of brown or black, making them less visible under the camper.

  3. Yes I to switched to the Sewer Solution and will never go back to those bulky hoses that are a pain to clean, so why did you not review this sewer system its the best.

  4. Where is the Valtera Sewer Solution high-pressure water powered macerator, with 1 inch diameter hose, that we have used successfully for 10 years?

  5. Valterra Sewer Solution hose. Pumps up hill and cleans itself. No disgusting corregated hose. I’m surprised it’s not on the list.
