Add Extra Length to Your RV Sewer Hose

hose extension connection

When your existing RV sewer hose isn't quite long enough to reach the dump inlet at the campground, you can use this extension hose to add 10' of length to your connection. Simply hook up the bayonet fitting on the extension hose to your RV's waste valve, then attach your existing hose to the extension's lug fitting. It's that easy.

Swivel Fittings Eliminate Twisting

Valterra swivel fittings

The swivel fittings on each end of the hose rotate independently. This means that the hose won't twist when you attach your drain hose, which ensures that waste easily flows when you dump your tanks. No twisting, no binding, no problem.

Video Transcript for Dominator RV Sewer Hose Review

Today we're going to be taking a look at the Dominator RV Sewer hose extension. It's available in five foot, with part number D04-0205. It's also available in 10 foot, with part number D04-0200. This RV sewer hose features a standard three inch bayonet fitting. It swivels for an easy connection. It can be connected directly to your RV's gray and black water tank, or to another three inch hose with a bayonet fitting.

This can help give us the extra length we need to get to our RV's dump station. You can also connect it directly to your RV's dump station with the addition of part number F02-3112CL. This is the Valterra 90 degree bayonet sewer fitting. It's made out of a tough, durable construction that's going to maintain its shape so that you can configure it any way you need it. The fittings on each end are pre-installed to insure a leak-proof connection. Our bayonet end features a rubber seal for additional leak protection.

When you're all done, it easily collapses down so you can store it in one of your RV's compartments. That's going to complete our look at the Dominator RV sewer hose extension.

Average Customer Rating:  4.9 out of 5 stars   (101 Customer Reviews)

Take this heavy-duty, 23-mil-thick, UV-resistant extension hose with you on your RV trip so you can always reach the campground dump station no matter where you park. Perfect for frequent RV trips.


I like this hose a lot BUT the connection's plastic is very stiff. I cannot attach or detach the hose from the dump pipe on my own, since it is too stiff to turn. I purchased a large wrench that is the right size, and that works well for attaching and detaching the hose. What I like about this hose is that I can make it short enough that it runs directly from my rig to the hole. With my old orange hose, I had to serpentine it in an elaborate fashion, which among other things negatively impacted the whole gravity part of the dumping equation.


Have used 3 times so far and works perf ectly!


Absolutely love these sewer hoses. You can compress or lengthen them into what ever length you need within the limits of the hose. Very manageable and easier to use than the "floppy" type hose. We already had 2 and have purchased 4 more (we have 2 sewer outlets and sometimes need quite a bit of length). Highly recommend.

GREAT !!!!!

I ordered tire and wheel covers, sewer hoses and end caps, 50amp to 30 amp adapter, and they work well with a great price


Perfect, thanks to your helpful web page showing which item I needed for my trailer.
Fast shipping. Great Service!


At most rv parks, an extension is not necessary but when needed, there is no alternative. I expect to only need it on a rare occasion.


Works great! Does what it should.


Heavy duty hose. Exactly what I hoped f or.


Fast shipping, good price.


Seems like a good delivery considering the distance


Great item and the service was out stan ding.


Arrive very quickly, even with the virus restrictions. Well packed, exactly as represented.


Product worked as advertised. Tight fit, good seal.





just what I needed to do the job right :]





Good quality.

  • Needing 70 Foot Long Black Water RV Sewer Hose
    Since we don't have a hose that's 70 feet long, you'll need to piece together a few hoses to get the length you're looking for. From the septic, I'd start with the EZ Coupler # D04-0115 with a 20 inch length and a 90 outlet for the septic tank. Then, I'd add 5 of the # D04-0200 hose extensions. The hoses use the typical bayonet/lug fittings that are compatible with the standard 3 inch lug fitting on your RV waste valve.

  • End Cap Set for Valterra Dominator RV Sewage Hoses
    The Valterra Dominator RV sewage hoses such as # D04-0200 and # D04-0205 have 3-inch bayonet and 3-inch swivel fittings on their two ends. The Camco RV Sewer Hose Storage Cap Set # CAM39753 will work on the bayonet end but the elbow cap will not. I tested the parts together myself to be sure. The correct end cap set for the Dominators hoses is part # T1020-3VP. I confirmed with Valterra.
