  • EZ Coupler

Great for long RV journeys, these durable 18-mil-thick sewer hoses connect together so you can easily dump your holding tanks. 4-In-1 clear elbow adapter fits 4 sizes of sewer inlets and lets you see when your tank is empty.

  • 4-in-1 Elbow easily connects to the dump station's sewer inlet
    • Fits 3" diameter slip and 3", 3-1/2", and 4" diameter threaded sewer inlets
    • 90-Degree elbow keeps hose from sharply bending and wearing down

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. Both durable hoses are made of 18-mil-thick vinyl, so they can handle bumps and scrapes. 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 Lug Fitting Eliminates Twisting

Valterra swivel lug fitting

The swiveling lug fittings on these hoses rotate independently. This means that, when you're screwing them onto your connection points, each 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.

This ez coupler 20' Deluxe Bayonet Sewer Kit in RED is exactly what I was looking for. I had a question about if it had the clear 90-degree bayonet fitting and the salesman had it pulled from the shelf to check it for me. The salesman was very nice and helpful. I would definitely do business with etrailer.com again We've had this product before and really liked it.

Great! We are very pleased with this.

This is perfect for what I wanted. Good hose

- D04-0115

Ordering was fast and easy. The product was delivered on time. Etrailer has been working great for me.

- D04-0115

This is an excellent septic system hook-up. The two hoses provide lots of length when needed, and clear L connector gives instant feedback about the status of your septic drainage. Also, the clear connector screws tightly into pvc pipe access points, creating a tight odorless connection.

Still works perfectly

the item was just as it was described and it arrived as promised

- D04-0115

So far so good. Like how it shrinks down to a smaller size. Replacing an older 20ft hose that was just too bulky when I only had a short distance and took up to much space. Will be putting it to the test next week.

Works great. Like it way better then the hose it replaced!

Had a thetford 15’ sewer hose kit but it wouldn’t compress back into original size and therefore wouldn’t fit in truck camper sewer tube holder. Chloe at etrailer recommended the ez coupler with 2 10’ hoses. It compresses back into original size and rarely have to use 2nd 10’ section. Seal at rv dump pipe drips a little But I’ll check to see why. Clear elbow is great. Better than translucent versions. Need to purchase special end caps for hoses since the kit doesn’t come with them. Extra $10 per pair. Make sure you get the correct ones.

- D04-0115

I called etrailer on a Tuesday to order a new EZ Coupler sewer kit as the hoses and connectors were getting old. This is the only sewer hose I will ever use. This hose and kit is durable and hooks together very easily to expand to 20 feet when needed. I also carry an additional 10’ spare hose in case one is damaged or on the rare occasion when 20’ is too short . I am a full timer and am on the road this whole summer. I ordered the kit to be delivered to the RV Park where I was arriving on Thursday and would be staying there for one week only. I made it clear it was imperative that I receive this kit in that timeframe. To my very pleasant surprise the kit was waiting for me at the RV Park when I arrived on Thursday with exactly what I ordered. Thank you etrailer.

- D04-0115

The hose split and leaked the first day I used it

Thank you for your review. Sounds to me like you received a defective hose. etrailers Customer Service takes care of defective parts if they arrive to you that way and especially if they have a 1 year warranty like this item. You can reach Customer Service via phone or email.

Good quality. Easy hook/unhook. Great aftermarket part.

- D04-0115

very hard to twist on and off. Also one developed a slit on the rubber one-inch from the coupler. I will be replacing these with a hose that has thicker material.

- D04-0115

The quality of all the products and accessories I have bought at e-trailer for my trailer conversion project is great: EZ Coupler RV Sewer Hose Kit w/ Swivel Fittings and 4-in-1 Clear Adapter - (2) 10' Long Hoses - D04-0115: Great Hose and couplers! Valterra Hydroflush Reverse Flush Adapter for RV Holding Tanks and Sewer Hoses - 45-Degree - F02-4100: Awesome solution to clean up the tanks thoroughly! Valterra Waste Valve for RV Black Water Tank - 3" Spigot to 3" Lug - T50A: Great valves so far! Scissor Stabilizer Jack - 18-3/4" Travel - 2,500 lbs - Qty 1 - TJSC-24: Great product, performing as expected.

- D04-0115

Hose seems good quality. Mounts fine however does not fit in my old storage tube. Again they might have changed mounts just enough to hang up in tube. I’ll just install a bigger storage tube.

Nice product at a decent price. I have not used it yet but I think it will work nicely. I love the connections which give you a 10' length or a 20' length. The clear end with the 3 OD's are great for the various sized dumps.

Thing works great!

Very good product, have had no problems.

- D04-0115

Due to where our sewer outlet is located, I've yet to need to use both hoses, but its nice to have the extra length if we ever encounter that situation. The 90 degree clear adapter is a super useful addition!

- D04-0115

Exactly what I needed. its going to work great. I have a 5th wheel parked behind a house i watch as the owner is not around. the hose stays out in the sun and gets messed with by the deer that move thru. I'm sure it will hold up as well if not better than the one it is replacing.

- D04-0115

Order came quickly . . .we're camping in 2 weeks and give better feedback then after using items.

- D04-0115

Just received it. Looks good so far and it will serve my needs since I have very short storage tubes. As always etrailer came through.

- D04-0115

Finally had a chance to use the new Trailer and the Sewer Hose worked as expected. The clear end makes it easy to see when the tank is finally empty.

- D04-0115

This has made the worst part of the camper experience so much better. The clear nozzle makes it easy to tell if you’ve gotten it all flushed out. The nozzle fits snugly in the hole so you don’t have to worry about it flopping out. Really worth the money

- D04-0115

Just got hose. Looks to be as advertised. Love the compressed length. Staff go out of their way to help you. Will be buying more from etrailer.com

- D04-0115

I am so impressed that I can place an order & have it delivered the next day! That’s fantastic! I won't be using the RV accessories that I ordered until this spring, but ai do appreciate your delivery capability!

- D04-0115

I bought these and used on our last trip; absolutely the best! I liked them so much that I discarded all the other hoses I own and bought a second set of these. They do not leak, they are flexible and the connections are easy to use. Originally, I did not think the clear end was necessary but after using it I changed my mind. The clear end is a real plus; lets me really see how clear (or dirty) the water is flowing and also the flow rate.

- D04-0115

Exactally as described. End swivels so always lined up. Solid gasket in end...makes for a great seal.

The hose works great and has never leaked over many, many uses. Just know that the big lugs on the end of these does not allow it to fit into most, if not all, storage sleeves. I had to custom make a carrier and brackets to attach to the trailer.
