Video Transcript for Valterra RV Sewer - Waste Valves - T84B Review

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.

Ordered the part on 10/10 and it was scheduled to be delivered on 10/17. I was surprised that it actually came early on Saturday 10/15. The quality looks good and it was exactly as described. Good experience with etrailer!


Installed it about 2 months ago, have not had any problems with it. Much needed upgrade on my '70s model Airstream, worked great in such a tight space, the only one I found that would fit. Also I really like doing business with etrailer, they always email you an update you on the status of your order, great customer service!


The waste valve and elbow fit perfectly, etrailer always comes through. Thanks


easy to use


We broke the original part five hours from home and no local shops had the part or could order in in less than three weeks. Gave etrailer a call and they set up shipping to the campground we we at in less than four days with expedited shipping. We received the part, better quality than the original and easy install. As a side note even with expedited shipping part was still cheaper than the local shops quoted me and they needed three weeks shipping time. Basically great part and amazing service.


The exact replacement part for my motorhome. easy install.

product is working as designed - no issues.

  • What is the Difference Between Double RV Waste Valves # T84 and # T84B
    The outlet tubes on Double RV Waste Valves # T84 are larger than those on Double RV Waste Valves # T84B. On the T84 the 3" Hubs slide OVER your RV's black-water lines. On the T84B the 3" Spigots slide INTO your RV's black-water lines. I have included links to videos on each.

  • Can the Exit Spout on the Double RV Waste Valves Part # T84B Rotate
    Yes, you can rotate the exit spout on the Double RV Waste Valves part # T84B just as you would the valves. However, in order to do this you are going to need to remove the four nuts and bolts on each side of the flange which over time is just going to create more leaks so I don't recommend it. It is also going to be very messy as you have to open the system up each time. If you are leaking out of the main spout then odds are the seals for the valves are not functioning properly and replacing...

  • Recommended Black Water Drains Transitioning To 4 Inch PVC Pipe
    To connect your RV to a 4 inch PVC pipe, I recommend the EZ Coupler 4-in-1 Threaded RV Sewer Adapter with 90-Degree Elbow Fitting - Clear # F02-3112CL. This adapter will transition from the standard 3 inch RV black water connections to the threaded 4 inch PVC. For your 3 inch connections, you may be interested in the Camco RV Sewer Hose Straight Adapters w/ Bayonet and Lug Fittings and Clamps # CAM39543. To get your two lines into one, you may want the RhinoFLEX RV Sewer Hose "Y" Fitting...
