Choose your hose length

These sewer hoses come with everything you need to empty your holding tanks at a dump station, particularly one that you're parked far away from. The 2 separate hoses let you adjust the length based on your setup. Use 1 hose when you're close to the dump station or connect both together for twice the length. Each extra-heavy-duty hose is made of 26-mil-thick TPE for maximum durability. The 90-degree elbow adapter prevents the hose it's attached to from bending too sharply at the sewer inlet, and because it's clear, it lets you see when the tank is empty too. The elbow adapter also makes it easy to connect to the dump station with its 4-in-1 fit capability.

Customizable Length Fits Every Trip

2 Hoses

Two hoses are included - a standard 10' drain hose and a 10' extension hose - to give you up to 20' of length when connected together. A typical 20' hose can be bulky and difficult to stow in your RV. Even worse, waste can get trapped between the coils of longer hoses, causing nasty odors. With 2 hoses, you get the best of both worlds. Use the standard 10' drain hose to reach the sewer inlets at most campgrounds. Connect the included extension hose to get a full 20' of length to reach inlets that are further away. And when you're done dumping your tanks, you can separate the 2 hoses for easy storage in your RV.

4-in-1 Elbow Adapter Fits Any Sewer Inlet

Valterra 4-1n-1 sewer adapter

The included 4-in-1 elbow makes connecting the hose to the dump station inlet fast and easy. The adapter is designed to fit 4 sizes of dump station inlets. It easily slides into 3" diameter slip inlets, and it can be screwed into a 3", 3-1/2", or 4" diameter threaded inlet.

Valterra 90-degree RV sewer hose fitting

Also, the 90-degree design ensures that there isn't a sharp bend in the hose when you connect it to the dump station inlet, which makes for a longer lasting hose. And the clear plastic construction of the elbow makes it easy to see when the water moving through your system runs clear, signaling that your tanks are empty.

Valterra 4-1n-1 sewer adapter installed

To hook up the adapter, slide or screw the elbow into the dump station sewer inlet, then connect the lug fitting on the end of the hose to the bayonet fitting on the adapter. It's that easy.

Extra-Heavy-Duty TPE Material Resists Crushing and Punctures

TPE hose

The RV hoses in this kit are made of 26-mil-thick thermoplastic elastomers (TPE) to provide maximum durability when you're dumping your tanks. The material is puncture and abrasion resistant, so you don't have to worry about springing a leak if the hoses get damaged from being dragged on the ground. TPE can also handle both hot and cold weather. UV resistance protects the hoses from sun damage, but the material also stays flexible in temperatures as low as -30 F. Finally, the wiring that runs around the hoses helps them to retain their shape, even if crushed or stepped on.

Swivel Fittings Eliminate Twisting

Valterra swivel lug fittings

The swivel fittings on each end of these hoses rotate independently. This means that, when you're screwing them onto the connection points, the entire hose will still lay flat. So when you're dumping your tanks, waste can easily flow to the sewer inlet. No twisting, no binding, no problem.

Viper RV Sewer Hoses w/ Swivel Fittings and 4-in-1 Clear Elbow Adapter - 20' Long - D04-0475

Average Customer Rating:  4.7 out of 5 stars   (97 Customer Reviews)

Built for the on-the-road lifestyle of full-time RVing, these extra-heavy-duty, 26-mil-thick sewer hoses offer maximum protection from crushes, punctures, and UV rays when emptying your tanks. 4-In-1 clear elbow adapter fits 4 sizes of sewer inlets.


First use noticed it will always extend with use. Had to install fully extended. One 10 foot section leaked shortly after started using. Then I discovered that this won’t mate up to Camcorder extreme hose without leaking most of the time. I threw the one good section in the trash. Might have used this expensive sewer hose for 6-8 months before it was junk


This hose is great. I bought 2 of them for a 3 month trip to Alaska. I only needed to use one of them. It worked perfectly well for me. I am glad I bought it over some of the other brands. It is tough, very well made, flexible and attached solid to my other accessories.

Frank L.


Its a superior product. Well built and solid!


This is a very rugged hose that pretty much keeps it's shape when collapsed or curved. Looks to be durable with outside ribs. Connectors are secure.

etrailer shipped with two other items in a very rugged box with good padding and it came very quick. Love this source for RV stuff. Have bought from them several times and continue to be impressed with their quality, communications, and service.


Great service thanks etrailer



Impossible to connect them together went back to cheap ones , very disapointed

The bayonet fittings on the end of the hose should definitely connect together. Would you be able to send pictures of how they did not connect? I would be happy to look into this for you.


If your hose getting crushed is your top concern, this hose is great. Certainly snaps back into round when smashed. However, if you expect a hose to collapse to the 50" length stated in the product description or hold any shape when not in use, you'll be disappointed. Maybe I got a dud, but an unwieldy sewer hose is not so much fun when it comes to storage (or use) – especially at this price point. Can't speak to overall durability since I've only had this for a couple of months. Will try to add pics at some point.


Just got these items and have not tried them in their real use yet. The hoses and elbow seemed to be of good quality. The caps that are used to seal the hoses when not in use are okay but are located and maintained only by a slight taper and may not stay in over a long time. I believe there are other hoses that "snap" to their closed state with more authority and may maintain that position better.


good quality hose, doesnt quite collapse back to original size but seems quite durable. Swivel fittings make it easy to attach to RV and has discharge nozzle included


This RV sewer hose has met all of my expectations. We've used it on 4 trips for a total of 15 days without any problems. No cracks and the connections have not leaked. Appears to be holding up very well and I expect we will get years of good use out of this hose.

Im still happy with this purchase. Additional 30+ nights of camping. Most with full sewer hookups. No leaks in the hose. No leaks in the seals. Very durable product.


well made and extremely well thought through. Obviously used sewer hoses before!


I have not had any issues with this drain hose, we have used it for one camping season thus far. It is far superior to other flimsy models.


Just received some of the items I had on order from etrailer. They appear to be in excellent condition and exactly what I needed. Besides that, I have never had anyone bend over backwards to assist and keep me informed as to the status of my order as these folks. The fellows at etrailer, Troy H. and George J. have gone out of their way in my humble opinion and you can be assured I'll do business with this company in the future.


I have been using this hose and elbow for a year now. Easy to use. No leaks. Only complaint is it didn’t fit in my bumper, had to add a holder under my bumper. Now elbow and hose fit, not attached to each other, but outside my camper


I received my order(s) the other day and all were packed well and arrived in great shape. I will be installing the waste valve system tomorrow on my 1955 Airstream restoration. I will provide photos when the job is complete. I am very pleased with the hands-on advice I received during the ordering process.


I could not find a good sewer hose at the RV stores
I found exactly what I needed on the website
Order came right in time and exactly what I ordered
Good company


The product is as advertised. Shipped in original box and on time. Good pricing. Sewer hose is a strong mil grade and should last for for years to come. Included 90 degree clear connection to sewer.


Works as it should, well made connectio ns


It worked as designed and is very sturdy for the price.


Seems to be of good quality. I bought it because of the hose wall thickness.


Excellent product and service delivered on time great people to work with they will be seeing more of my business thanks


I only used this once so far, but it worked great! The hose didn't trap anything on the way through like some other hoses I have used. Very flexible and easy to work with. NO leaking at the connection points.


Have not used the products yet.... But what really impressed me was how the items were packed, in a VERY sturdy box with ample packing material, thank you! Will be making another order soon.


After a year in continuous service we are very pleased with the viper hose.


Good quality product that does what it is supposed to do.


Excellent service. Great product. Shipped and received right on time


Very good. Easy to use and store

  • Will the Viper RV Sewer Hose # D04-0475 Store in a Typical 4" Bumper
    I went out to the warehouse and measured the bayonet fittings on both ends of the 3" diameter Viper RV Sewer Hose # D04-0475. As you can see from the attached photos the end with the nubs on it measured 4-1/4" wide while the bayonet fitting end measured 4-1/8" wide. This will fit a 4" x 4" bumper as long as you don't have the 90 degree elbow installed and the fittings are turned to the corners.

  • Recommended Sewer Hose for Aliner Grand Ascape Plus
    I do have some great sewer hose options but they aren't trailer specific so if there is anything special about the Aliner Grand Ascape Plus, I'm not aware. That said, most trailers come with bayonet fittings on the end of the waste valves which allows you to use a hose like the Viper RV Sewer Hose part # D04-0475. Therefore, so long as you have those fittings that is what I recommend. If you have some other sort of setup, feel free to send some photos over or browse our selection below.

    The Lippert Waster Master RV Sewer Hose, # LC359724, is designed to be stored in the under bin compartments of RVs. The hose and nozzle will not fit in the bumper style storage tubes. I do have a solution for you. The Valterra Viper RV Sewer Kit # D04-0475, has two 10 feet hose that can be connected to make a 20 foot section. The hose is made of a heavy-duty plastic that is puncture resistant. The kit also includes a detachable clear plastic 90-degree elbow. However, this brand sewer hose...

  • Recommended Hose Carrier For # D04-047 Sewer Hose
    I went to the warehouse and took a measurement of the Quick Drain Sewer Hose # D04-0047. It is right at 3 inches diameter and when compressed it measures 10-1/2 inches. The hose carrier I recommend for your hose is the Valterra EZ # A04-0150XBK. This tube measures 26 inches long and the inner diameter of the carrier is 4-3/8 inches so your waste tube will easily fit.

The Valterra Rotating "Y" Sewer Connector - 3" # F02-2030. Or the RhinoFLEX RV Sewer Hose "Y" Fitting # CAM39812. With these two options I do recommend the Valterra Rotating Y # F02-2030, it has a nice swivel lug fitting and internal seals to help prevent leaking at connection points.

  • Best Heavy Duty 20' Sewer Hose Kit For RV Campers.
    I recommend the Viper RV Sewer Hose Kit # D04-0475. This is our thickest hose at 26mils TPE so it will resist crushing, punctures, and UV damage. It also stays flexible even in cold temperatures. The kit contains two 10' hoses so you can use one if you only need one which is better than having to trying to bunch up a 20' hose. Also included is a 4-1 clear elbow that fits 3" slip, 3", 3-1/2", and 4" threaded sewer points. The clear elbow helps you ensure that the hose and system are clean...

    I recommend using the Viper RV Sewer Hose Kit # D04-0475 to use with the Flush King Reverse Flush Valve # F02-4350. This sewer hose kit come with two 10' hoses so that you can just use one if you are able to get closer to the dump site.
