RV sewer elbow combines rotating black-water waste valves. 3" Hubs slide over 3 separate black-water lines. Handles sold separately.
Features:
This RV sewer elbow with rotating valves is a part of your motor home's waste management system. The elbow combines the flow of wastewater from your black-water tanks. And the valves can be rotated as desired during setup to make it easier to reach.

Today we're going to be taking a look at the Valterra double-rotating waste valve. This unit combines two sources of three-inch piping to one outlet. It's made from a durable black plastic construction. The unit's going to feature your two three-inch Bladex valves. You can see here that it has the threaded posts on those valves, but the actual handles, the T-handles, are not included. The shaft is there to control the valve up and down, but the handles are sold separately, and you can find those at etrailer.com. The valves are also designed to rotate for easy accessibility, 360 degrees.
It will rotate all the way around, so that way you can position it in a way that works best for your application. All the connections on the system are three-inch hubs, so you're going to have three three-inch hubs. They all have an inner diameter of 3-1/2 inches. Your three-inch piping would fit into the ends of the unit and secure using the appropriate glue or solvent, which is sold separately. If you're in need of that, you can find it here at etrailer.com. That's going to do it for today's look at the Valterra double-rotating waste valve..

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.

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.
