Your Guide To RV Sewer Hose Fittings
Talking about sewer hose fittings and emptying your black is not something that gets a lot of play around the campfire. Of course, it’s been said before, “it’s a dirty job, but somebody has to do it.” When you think about it, it really is a disgusting part of the whole RVing experience.
Does it really matter if your sewer hose fittings are top-of-the-line or just mediocre? How do I know what sewer hose to buy? What happens if my sewer hose fails?
These are all legitimate questions, so let’s look at some aspects of emptying your tank and what the best RV sewer hose fittings are to make your job a little less off-putting.
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.
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.
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.
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.
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.
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.
