RV sewer elbow combines rotating black-water and gray-water waste valves. 3" Spigot slides into black-water line. 1-1/2" Spigot slides into gray-water line. 3" Spigot slides into a separate sewer line.
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 gray-water tank and your black-water tank. And the valves can be rotated as desired during setup to make it easier to reach.

Speaker 1: Today we're taking a look at the Valterra double rotating RV Waste Valve. Now, this RV sewer elbow, combines a inch and a half waste valve and a three inch waste valve. It can be used as a replacement part, or to upgrade your existing set up. Now, the elbow merges the flow of waste from your black water tank and gray water tank.It's a really nice, durable design. It has the blade-x valves on it. Very easy to control and operate.
So you can see how that opens and closes the valve. Does feature the metal stems right here, so it's a nice durable construction. Now these are rotating valves, so these can rotate 360 degrees. Really offers easy access at the mounting locations. And each valve rotates that same way.So you can position the valves at the desired angle, when you're installing the unit.
This connection point right here, is your three inch spicket. Slides into your RV's black water line. Outer diameter on this one, is 3-1/2 inches. Then on this side, we have an inch and a half spicket, slides into your gray water line; outer diameter is 1-7/8. And then right here, you have another three inch spicket, which you slide into a separate sewer line.
Again, outer diameter 3-1/2 inches.The unit is constructed of a durable ABS plastic construction, black in color. When installing this, you will need some ABS solvent cement. It is required for installation, and it is sold separately. If you're in need of that, you can pick it up here at etrailer.com. Last think I want to mention, is that it does have the gray and black handles, which allow for easy identification of which valve is which.
That's going to do it for today's look at the Valterra double rotating RV Waste Valve.
Ratings & Reviews
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.
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.
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.

Just installed the elbow yesterday and still need to see how it performs. It was not an easy DIY job with limited workspace underneath the chassis and mostly rusted parts. But the money saved and the knowledge learned in the process make it worthwhile. The ordering was really smooth with the status update constantly provided. Highly recommend etrailer
Replaced old valve assemble 1992 class C RV with new valve. It was a perfect fit.
This was the perfect part, and it fit right into as replacement from the old one. Very easy to install.
