Not the most pleasant repair to do, but this is a perfect fit for my cracked valve assembly. My original was 16-years old and I didn't want to mess with a piecemeal repair. This takes care of everything. The valves themselves have a metal pull bar and the ABS body looks like it'll last forever.

Ask the Experts about this Valterra RV Waste Valves

  • How to Remove Old Sewage Drain Assembly to Install Valterra Double RV Waste Valves
    Yes, when replacing sewer parts that have been installed with ABS Solvent Cement like part # A05-0303 you will need to cut the pipe right where the old valve is installed so you can install the Valterra Waste Valves # TR38. If you think this will reduce your sewer pipe by too much then you may need to cut most of the old pipe off and add a new piece that is about the same current length. We don't carry any replacement pipe but you should be able to find some at your local hardware or...

  • How to Choose Correct Valterra Double RV Waste Valves Replacement
    You should be able to tell which Valterra Double RV Waste Valves you need by inspecting your current connection points. The one end with the lugs on it is the same on all 3 parts so you simply need to determine if you need hubs, spigots, or a combination of both. A hub connection fits around the spigot so you just need to check the other side of your waste valves to see if the adapter has fittings that connect on the inside or outside of the pipe they are connected to. Then you just...

  • Parts Needed For Replacing 1-1/2" and 3" Sewer Coupler With One That Has Waste Valves
    It appears that you will only need the Valterra Street DWV Fitting # D50-2890 to be able to install the Double RV Waste Valves # TR38 on your sewer system. The main Y of the assembly is likely identical to yours with the waste valves attached to the ends. You will likely be able to cut the ABS pipe at the end of the couplers and not need to extend any of your lines as the waste valve will make up for the portion that you cut off. I have attached a image with the dimensions of the coupler...

  • What is Difference Between Double Waste Valves # TR38, # TR38A, and # TR38B
    The difference between the part numbers you mentioned of # TR38, # TR38A and # TR38B comes down to the difference between spigots and hubs in terms of how these valves install. So hubs fit OVER a pipe and spigots fit INTO a pipe. So the part # TR38A has a 3 inch spigot and a 1-1/2 inch hub # TR38 has a hub for both fitting sizes # TR38B has a 3 inch spigot and a 1-1/2 inch hub.

  • Double RV Waste Valves for Gray and Black Water Valve
    Thanks for the photo and based on that we do have a replacement that will work for you although you are going to need to know what your gray water pipe and black water pipe connections are - either spigot or hub - which I'll explain but you are going to need to remove your valve to find this out. Basically, hubs on the valves slide OVER your RV's water lines while the spigots on the valves slide INTO the water lines. When you take off your current valve, pay attention to if it slides...

  • Differences Between Three Valterra Double RV Waste Valves
    The difference between the three valves are their fittings. The hubs on the valves slide over your RV's water lines while the spigots on the valves slide into the water lines. Valve # TR38 has a 3" hub and 1-1/2" hub, both of which slide over your water lines. The 3" hub slides over your RV's black-water line while the 1-1/2" hub slides over your gray-water line. Valve # TR38A has a 3" spigot and 1-1/2" hub, and the 3" spigot slides into your RV's black-water line while the 1-1/2"...

  • Which RV Double Waste Valve Is Needed for a 2018 Winnebago Minnie Winnie 2108DS
    I have a solution for you, but we don't have access to information that tells us exactly what pipes are found on particular coaches. The # TR38A has a spigot for the black water pipe and a hub for the grey water pipe, so if your coach has those fittings then this would be the correct valve for your 2018 Minnie Winnie 2108ds. You will need to remove the current valves to determine which fittings are on your grey and black water pipes, but for reference- hubs on the valves slide OVER...
