It worked
A tire blew out and took out the black and Grey water clean out. I was able to save several hundred dollars fixing it myself. This part worked and was easy to install.

For my travel trailer.
This assembly fits my 2004 Trailmanor 2720 SL perfectly, direct replacement for original...only have to rotate black valve 180 degrees.

Worth the price
This was a necessity and fit perfectly but the gasket slipped a few times before I had to use a longer and better nut and bolt.

Works Great so far
I bought the Valterra San Tee Double Rotating Valve in June 2025 and installed it myself—it was easy and straightforward. So far it’s working great: no leaks, and it opens and closes smoothly every time. Reliable, simple to use, and exactly what I needed!

Your grey and black tank valves are very important if you plan to use water/shower and the toilet in your RV. The previous owner must have hit the old valve on something because it was broken off clean. This valve perfectly matched the old one that was on my RV. The downside is you have to unbolt everything and bolt it onto your RV directly unless you plan to connect the entire unit with new PVC pipes. Good news it bolted on perfectly with no leaks. Great product and great price, would highly recommend for anyone who needs to replace their valve.

Product arrived on time and was as expected. With our trailer setup, this double valve was easy to install. We now have a dual layer of protection from leaky valves. When draining tanks, I now open the appropriate valve on the new double valve assembly and then the existing tank valve. Once tank has drained, I then close existing valve and wait a bit for residual fluid to drain and then close valve on double valve assembly. Hope this will keep new valves from leaking over time!
