RV sewer elbow combines rotating black-water waste valves. 3" Spigots slide into 2 separate black-water lines. Bayonet cap fits over the 3" lug fitting that connects to your sewer hose.
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. Connect your sewer hose to the 3" lug fitting on the elbow and open the valves to drain your holding tanks.

Today we're going to take a look at the Valterra RV Rotating Double Ell Waste Valve assembly. It has a 3-inch spigot end on each end and a 3-inch bayonet cap end. This is made of a durable hard plastic construction. It is designed for installation on a black water system. The double ell design if you look at it, basically the two tubes you can see form a double ell look to it. The bayonet end right here is designed for use with this included bayonet cap.
You can see the cap is tethered to the tube so you won't lost it or you can connect the drain hose to this bayonet fitting. A bayonet fitting has the 4 pins on the tube and then the cap or the drain hose whichever you use, will have hooks on it either 2 or 4, that you would just twist on there and it locks it and gives you a nice secure connection. Both of these waste valve bodies right here, they are a Bladex design and these are used to open or close the tube opening at each end. Just like that they're open or closed. What's nice about this .. Let me open both of them.
If you look through there it gives you a nice 3-inch diameter passage which will allow the waste to travel freely when they're open and then when you close it, the valves will tightly seal off the black water pipes when it's closed. Both of these valve bodies can be rotated on the pipe to fit your specific application. If you need to put the handle in a position where you can reach it, all you have to do is remove the 4 nuts and bolts, rotate the valve body to your desired position and then tighten it down. Both of these valve bodies have the metal valve shafts. You can see when I pull it out they have metal valve shafts and plastic end handles on each end. I do want to give you a few dimensions. The spigot ends which are on each end here, they have the same inside or internal diameter and that's going to be right at 3 inches.
On the bayonet cap end, we'll take the cap off. If I put a ruler in there, you can see they're going to be 3-inch inside diameter also. That should do it for the review on the Valterra RV Rotating Double Ell Waste Valve assembly, 3-inch spigot ends on each end and a bayonet cap end.

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?
