Complete kit

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. The heavy-duty hoses are made of 23-mil-thick poly material for extra durability. The 90-degree elbow adapter prevents the hose it's attached to from bending too sharply, 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.

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.

I had placed an order for a few items, the items arrived just a few days later. I highly recommend placing orders with


There was a delay in shipping the product from the manufacturer. The etrailer folks did an excellent job keeping me updated on the status of my order.


Quality product. I was hoping it would fit inside my RV 4" rear bumper. The hose fits but the ends are to big a diameter to go inside the 4" square tubing. Just have to store elsewhere.


Makes a rough job easier and that's always a plus. Great delivery time.


Great investment! Holding up great after several camping trips. We average 6 to 7 trips per year with 8 to 14 days each trip.


The hose was perfect. Semi stuff, well made. You Can pull or push it together And it stays in place.


Product arrived as ordered - very efficient - I feel certain that it will function as it
is supposed to - but I rated a 4 since I have not used it yet. Very satisfied at this point.


We haven't had a chance to use it yet, but it looks like very good quality.


After one year of heavy use, this hose is like new and performs great. Like it's collapsibility. I would highly recommend it.


Very brittle


The product is exactly what I wanted. The right length & quality.


I purchased this to replace my old one, it feels stronger I hope it last longer.


Great product, was all that was advertised, shipped quick, packaged well. Will order from again,


works great


The best!


Great Support, David was great with finding the i needed.


worked great.


Came in just as the product showed on the website.
