Complete kit

This sewer hose comes with everything you need to empty your holding tanks at a dump station. The extra-heavy-duty hose is made of 26-mil-thick TPE for maximum durability. The 90-degree elbow adapter prevents the hose 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.

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

This RV hose is 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 hose gets damaged from being dragged on the ground. TPE can also handle both hot and cold weather. UV resistance protects the hose from sun damage, but the material also stays flexible in temperatures as low as -30 F. Finally, the wiring that runs around the hose helps it to retain its shape, even if it gets crushed or stepped on.

Swivel Fittings Eliminate Twisting

Valterra swivel lug fittings

The swivel fittings on each end of this hose 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.

Video Transcript for Viper RV Sewer - Hoses - D04-0450 Review

Speaker 1: Today we're taking a look at the Valterra Viper RV sewer hose. This sewer hose lets you drain your RV's black water and gray water tanks at a dump station. It features the easy coupler. This is a four in one elbow adapter that makes it easy to connect to the dump station. It fits a three inch slip, three inch, three and a half inch and four inch threaded sewer inlets. It's a 90 degree elbow, so that really helps reduce stress on the hose by preventing it from bending at a sharp angle and it's a clear plastic, which allows you to easily see when your tanks are empty, or if you're cleaning out the tanks, it allows you to see when the tanks are clean because you can see right through it.

It's a nice design. Again, clear plastic lets you easily see when the tanks are empty or when your water is running clean.On this end right here, it features a swivel lug fitting. This rotates to ensure that the hose always lays flat when making connections. You can see right here that these two components easily connect to one another. Right there on that easy coupler fitting, we have an internal seal, which is going to help prevent leaking.

You can see how that can swivel. It ensures that our hose lays flat, no kinking or binding.On this end, we have a swivel bayonet style fitting that would easily attach to a standard three inch lug fitting on an RV waste valve. Again, it has the internal seal to help prevent leakage. Then, this is an extra heavy duty 25 milled TPE hose that's UV resistant and puncture resistant. It features wire reinforced design, so if it was to get stepped on or driven over, it springs back into shape pretty easily and pretty quickly.

It's a really nice design. It remains flexible in a variety of temperatures. It's been tested in cold temperature down to negative 30 degrees fahrenheit. When you're ready to use it, you can see how you can just extend it. It's gray in color with red accents.

Then, when you're done with it, it collapses for easy and convenient storage. This is a three inch diameter sewer hose. When fully extended, it has a length measurement of 15 feet long.That's going to do it for today's look at the Viper RV Sewer Hose from Valterra.

I disassembled the unit to install permanently in my class A DP receiver tube. I removed one of the ends and was able to clamp it directly onto my 90° connection at my valve. The coil on the Viper hose is thicker than the cheaper waste hoses and I was only able to compress 12 foot of the hose into my storage tube. Previous “old” hose, I could get a 15 foot segment. I guess for the durability, that’s a good thing. Always great to deal with etrailer for product support and a great price.

- D04-0450

Product appears to function fine. Have only used it twice. The product was not what etrailer videotaped and specified for color and specs. The manufacturer had changed manufacturing specs on the product that etrailer said they were not aware of. Went to a lighter guage material and added red colored ribs to prevent leaks when dragging along the ground. Another issue was another assembly using 2 -10 ft lengths was initially ordered and I was told by etrailer that the product was back-ordered and would be shipped to me by a certain time. That time came and went and we needed it right away for our trip. Needless to say we had to change for another length assembly they had in stock which did not resemble the product they advertised. As far as performance the product worked. It however did not want to stay in any compressed state and lay flat along the desired length.

The same, the 15 section that had the new changed specs still does not stay in a compressed state if needed and it will not hold a straight course, tends to meander, unless fully extended. When storing I purchased 2 end caps that seal both ends of the hose and allow the hose to remain in a compressed state for storage.

This hose is a major improvement over the cheap ones at dealerships. Much more robust design, because of the length, collapsing the hose for storage is a bit awkward. The clear, universal output connector is a great idea.

- D04-0450

I am a fulltime RVer. This hose has worked great for me. I had a chipmunk in California chew a small hole in it and the manufacturer sent me a brand new one without hesitation. One drawback to this hose is once you use it, it will never go back to the compressed length that it came in requiring a little more storage space than I anticipated. Also if you have a place on your RV for hose storage, it will not work. The collars are too big to fit in the storage receptacle. Overall, great hose, very durable.

- D04-0450

I ordered this hose (15') and a 10'. I thought they were both supposed to be the heavy duty 26 mil. The 15' has a red spiral stripe running its length and the 10' is a plain grey color running its length. The 3 stars is because the swivel end that the 90 degree dump fitting hooks up to on the 15' hose is frozen, stuck, jammed or something and doesn't turn freely as it is designed to do. These are probably good products but quality control (if it exists) let this one out the gate without having it fixed, and sent it on to the customer. Maybe the assembler was the culprit?

- D04-0450

Quick shipping, received exactly what I ordered. Have not used the product yet, purchased based on reviews of product.

Review from a similar Viper in RV Sewer Hoses

The following pics. Uploaded were purchased from e.trailer com The marker light was a perfect fit. The sewer hose works ok unloading from holding tanks to honey wagon,then honey wagon to dump station. If the hose was another foot longer it would be perfect when dumping. My question is can I get this same hose with the same fittings in a 3 or 4 ft. Length ?

RV Viper hose still in service after a year of dumping daily. Noticed a slight dripping at the bayonet fitting, not significant to take out of service.

Review from a similar Viper in RV Sewer Hoses

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.

Its a superior product. Well built and solid!

Ideal 'extra' length for use with 10' section of existing Viper hose.

Review from a similar Viper in RV Sewer Hoses

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.

Review from a similar Viper in RV Sewer Hoses

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.

Review from a similar Viper in RV Sewer Hoses

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.

Review from a similar Viper in RV Sewer Hoses

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
