Use 1 hose when close to the dump station, or connect both hoses for twice the length.

The elbow adapter also makes it easy to connect to the dump station with it's 4-in-1 fit capability.

Clear Plastic 90-Degree Elbow

Valterra 90-degree RV sewer hose fitting

The 90-degree elbow on the sewer adapter ensures that there isn't a sharp bend in the hose at the dump station connection. This prevents unnecessary wear and tear on the sewer hose. And the clear plastic construction of the elbow makes it easy to see when your tanks are empty. You can easily connect the bayonet fitting on the adapter to the lug fitting on the end of the hose.

4-in-1 Sewer Adapter

Valterra 4-1n-1 sewer adapter

The 4-in-1 adapter is designed to fit 4 sizes of dump station inlets. It fits 3" slip inlets, as well as 3", 3-1/2", and 4" threaded pipes.

Swivel Fittings

Valterra swivel lug fittings

The swivel lug fittings on the end of each hose rotate to ensure that the hose lays flat when making connections. As you twist the bayonet fittings over the lugs, simply rotate the lug fittings to secure the connection.

Video Transcript for EZ Coupler RV Sewer Hose Kit Review

Speaker 1: Today we're going to be taking a look at the Valterra EZ-Coupler RV sewer hose kit. The 10 foot part number is D04-0114 and the 20 foot long part number is D04-0115. This kit comes with everything you need to connect your RV's black water tank to a dump station. When emptying out your tank and connecting it up, you'll want to wear gloves. A box of disposable gloves can be found at e-trailer.com. The 3" diameter vinyl hose has an 18-mil rating and is UV resistant.

The RV end features a Bayonet fitting, which easily attaches to your black and gray water tank. The other end features a 90-degree elbow, a 3" slip fitting, a 3" threaded, 3 1/2" threaded, and a 4" threaded. Clear plastic lets you know when your tank is empty.It features a swivel fitting to easily adjust to your dump station. Internal seals help prevent leakage at both connection points. The sewer end feature a lug fitting, which will allow you to connect to different sewer accessories.

The highly visible red color will help it stand out to prevent tripping or accidents. Remember to empty your black water tank first, followed by your gray water tank. This will help flush out any remaining waste. When you're all done, it easily compresses for storage. That completes our look at the Valterra EZ-Couple RV sewer hose kit..

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. 445686

Thing works great!

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. 445481

- 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! 470208

- 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. 575824

Still works perfectly

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. 284717

Great! We are very pleased with this.

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. 519317

These work perfectly and, after shopping around, were a good price for a good product. We've used them for over a year with no problems. 737655

- D04-0115

This has been a great product. As advertised. Haven't used it much but so far I really like having two shorter hoses instead of one long one. 736224

- D04-0115

Great sewer hose. Holds up very well after many uses. 727460

- D04-0115

Always quick and excellent service! 713634

- 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 711918

- D04-0115

Great product. Worked well for our need s. 698825

- 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. 698129

- D04-0115

I was looking for a product that was durable and capable of collapsing to a reasonable size. This fits the bill. As usual etrailer is a pleasure to work with before and after purchase. Thanks 692191

- 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. 665848

- 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 661386

- D04-0115

very useful 654113

- D04-0115

Much better than my original set up 652327

- 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. 651972

- D04-0115

Product as described. Have not used it, but looks like it will get the job done. 639992

- D04-0115

Appears to be a very solid set of hoses with good connectors. 639392

- 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! 635023

- 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. 615404

- D04-0115

Order came quickly . . .we're camping in 2 weeks and give better feedback then after using items. 612927

- D04-0115

Fast delivery and affordable, will shop here again 611345
