Today we're going to be taking a look at the Valterra double rotating waste valve. This unit combines two sources of 3" piping to one outlet. It's made from a durable, black plastic construction. The unit's going to feature two 3" bladex valves, one's going to have a black T handle, the other one has a gray T handle. The shafts are made from a durable metal construction and the handles are plastic.Now internally it's going to come with all the necessary seals already installed and built in. Those are going to offer leak proof performance.
These valves are designed to rotate 360 degrees. Each one will rotate just as I showed that one do. That way you can get it into a position that works best for your installation application. The unit's going to feature two 3" spigots, and then it's going to have one 3" hub outlet. The spigots are going to have an inner diameter of 3", outer diameter of 3.5".
Each one's going to measure the same. Then the hub has an inner diameter of 3.5". Now if you're in need of some ABS solvent cement to make your connections, you can find that right here at etrailer.com, part number A05-0303. That's going to do it for today's look at the Valterra double rotating waste valve.

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?

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.
