The grey water part of this is too short to fit our 2017 Jayco Jayflight SLX. We need the part with a longer grey connection.

Installation was a breeze. I purchased a 2ft section of 3" & 1-1/2" ABS pipe, two 1-1/2" right angle, one 1-1/2"coupler and one 3" coupler, cleaner (MEK/Acetone) and ABS cement. I cut all pieces first fitted them all first before gluing. Prepared all sections with cleaner first before applying ABS cement. Pictures show the "before" with duct tape in leaking sections.

The installation looks clean Jake! Really appreciate the before and after photos as well. Feeback like this really helps the next person looking to tackle this themselves.

I have a 2025 Winnebago View 24D with cable actuated dump valves, which either don't close and leak or are just very difficult to use..So I replumbed it to like the 2012 24J Winnebago View we traded in on the 2025.  New valves are easier to operate and close tightly, looking forward to years of no problems now..been rving for 52 years never had these problems with any other rvs we have owned..Thanks for the parts

Works great. I made a plan and upgraded my RV waste plumbing to be 3" for both the black and grey tanks. Additionally I used flexible rubber fittings for some of the longer pieces instead of gluing it all together. This will be more serviceable in the future if any of the sections of pipe were to fail. I had to replace this valve because the grey tank pipe split along the pipe seam for the second time. Overall, this valve was exactly what I expected and fit with my plumbing plan perfectly.

That sounds like a really solid upgrade. Moving both your black and gray tanks to 3" plumbing and using flexible rubber fittings is a smart call especially for future serviceability. It’s great to hear the valve fit right into your setup and worked exactly as expected. Hopefully that helps prevent any more issues with those pipe seams going forward. Thanks for sharing your experience! What kind of RV do you have?

part arrived on time and worked as designed, it was kind of a challenge to get it installed but the fit was perfect

Thanks for the picture Jose. The new valve looks great. Those sure are difficult to install so glad you were able to get it all set up and it fit so well.

by:
I just gave it an average because I should have ordered a gate vale with just a 1 1/2 in. outlet positioned another way. The 1 1/2 on this one was facing outward causing the whole valve system to be too long and set the tank too far back under the trailer. I used it, however I cut the 1 1/2 value outlet off and plugged the hole and I will feed my shower drain and sink drain into the 2 in. outlet and close it off when needed with the extra gate I ordered for the 2 in. outlet..
by:
The double waste valve assembly looked pretty well-made. However, I had to return it as the ends didn't match my motorhome. I chatted with Audrey through email and she was very helpful.
I tried to contact e-Trailer shortly after I ordered it, to cancel. Their customer Service process is crap. It took 3 business days for them to respond. By then the order had shipped. Bottom line, I had to pay the return shipping. I'll just go back to [online vendor]. Free returns.

  • Kit to Charge Battery of 2015 Chevy Equinox When Flat Towing
    Yes, we have the Roadmaster charge wire kit part # RM-156-25 which gives you the needed wiring and breaker to run a power wire from the tow vehicle to the battery of your 2015 Chevy Equinox. I attached an install video for this kit on a similar 2016 Equinox as well.

  • What is the Difference Between Valterra Double RV Waste Valves # T80, # T80C, and # T80A
    The differences between the Valterra # T80, # T80C, and # T80A simply has to do with the types of connections that they have. They vary between Hub (female) and Spigot (male) ends to suit your needs. The ends that change are on the side. The top of each part number has a bayonet cap that fits over a 3" lug fitting for your sewer hose. Part # T80 has a 3" Hub (female) and a 1-1/2" Hub (male) Part # T80C has a 3" Hub (female) and a 1-1/2" Spigot (male) Part # T80A has a 3" Spigot (male)...

  • Replacement Double RV Waste Valves Recommendation for RV
    Thanks for the picture. From that I can point you towards the correct valve setup to replace what's in it as part # T80A. But for the rest of the piping we won't be able to help you as we do not carry it. There are a few different variations of the valve though. Part # T80 has a 3" Hub (female) and a 1-1/2" Hub (male) Part # T80C has a 3" Hub (female) and a 1-1/2" Spigot (male) Part # T80A has a 3" Spigot (male) and a 1-1/2" Hub (female)

  • Difference Between Hub and Spigot for Valterra Double Waste Valves

  • Comparing the Double RV Waste Valves Part T80C and Part T80
    The difference between the Double RV Waste Valves part # T80C and part # T80 is that the former has a 1-1/2" spigot fitting and the latter has a 1-1/2" hub fitting. They both have 3" hub fittings as well. The spigot fitting means this will slide into the pipe and the hub fitting means this will slide over the pipe. The hub fittings are more common for the valves. In order to attach either assembly you will also need the Valterra ABS Solvent Cement part # A05-0303.

  • Difference Between Valterra Double Rotating Waste Valve T80 and T80C
    The difference is that the part # T80C has a spigot on the 1-1/2 inch side and the # T80 has a hub instead. A hub needs to mate to a spigot and a spigot mates to a hub. So you application determines which you would need.
