Exactly as advertised, great quality product. This is the direct replacement for the one on my 5th wheel. I haven't had a chance to install it yet, but looking forward to getting it done. I love that it comes as a COMPLETE unit with valves and cap.




by:

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.

  • Differences between Valterra Sewer Wye # TR38, TR38A and TR38B
    The difference between all three of the part numbers is the difference between a "hub" and a "spigot." The hubs fit over the spigots so it's basically the style of fitting you need. The part # TR38 has a hub and a hub for bot the 3 inch side and the 1-1/2 inch side opening. The part # TR38B has a 3 inch spigot and a 1-1/2 inch spigot. The part # TR38A has a 3 inch spigot and a 1-1/2 inch hub.

  • 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" hub...

  • 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 need...

  • 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 your...

  • 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.

  • Differences Between Valterra Double RV Waste Valve Models
    The difference between these models is the connection points for the black and gray water pipes. A hub will fit over a pipe while a spigot will fit inside of a pipe. You'll just need to choose the correct connection type for your current piping. The # TR38 is a 3" Hub and 1-1/2" Hub. The # TR38A is a 3" Spigot and 1-1/2" Hub. The # TR38B is a 3" Spigot and 1-1/2" Spigot. The # T38C is a 3" Hub and 1-1/2" Spigot.

  • How Much to Tighten Bolts on Double RV Waste Valves - Sewer Wye - Rotating - 3" Hub and 1-1/2" Hub
    In regards to the Double RV Waste Valves part # TR38, you'll tighten the bolts hand tight until snug and then use your wrench another half turn or so. If you have leaks you can go back and snug them down more but you can't unbreak the plastic flanges so it's best to progressively work your way up in regards to the torque.

  • Comparing the Valterra Sewer Wye Part T38 and Part TR38
    The Double RV Waste Valves part # T38 has rotating valves on both the black water 3" hub outlet and the grey water 1-1/2" hub outlet whereas the Double RV Waste Valves part # TR38 only has a rotating valve on the grey water 1-1/2" hub outlet.

  • 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 into...

  • Recommended Replacement Double RV Waste Valve
    From the picture you provided, it does look like the Double RV Waste Valves - Sewer Wye - Rotating - 3" Spigot and 1-1/2" Spigot # TR38B will be the correct fit for you. However, I will say it is a good idea to measure the 2 pipes going into the valve to make sure they match the 1 1/2" and 3" ports.

  • Could Double RV Waste Valves # TR38A Fit 1992 Hyline 28ft Camper
    We don't have a way to look up what your 1992 Hyline camper would have on it but the Double RV Waste Valves # TR38A most likely does work for you. What you'll need to check is how your current valve setup fits the pipes of your RV. If the 3 inch valve side slips into the 3 inch pipe of the RV and the 1-1/2 inch side fits over this is exactly what you'll need.

  • How Do You Connect The Valterra Double RV Waste Valves # TR38 To The Gray And Black Water Pipes

  • 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 home...

  • Is There a Way to Use Double RV Waste Valves - Sewer Wye with Two 1-1/2 Pipes
    I do have an option for you but none of our sewer wye valves feature two 1-1/2" inlet pipes into a single 3" outlet. That said, you can still use something like the Double RV Waste Valves - Sewer Wye part # TR38 by just reducing the 3" hub down to a 1-1/2" hub with the Valterra Eccentric Tank Reducer part # T1041-1. This would give you a 1-1/2" spigot and 1-1/2" hub but that's the best we can do.

    I would be happy to recommend a replacement waste valve for you, but unfortunately we do not have a break down of which style waste valve is used on a specific RV. A few of the different styles are a single 3" waste valve like the Valterra Waste Valve for RV Black Water Tank - 3" Spigot to 3" Lug # T50A, or a combined black water and grey water valve like the Double RV Waste Valves - Sewer Wye - Rotating - 3" Spigot and 1-1/2" Hub # TR38A.

  • Dual Sewer Valve Replacement for 1997 Hornet by Damon RV
    Based on the picture you sent in you'd need a sewer tee and not a wye since the angle of the two pipes is 90 degrees relative to each other in your picture. For that we have the part # T18A which would match the orientation of your pipes. I attached an install picture that shows it installed on a similar setup.

  • Does the Double RV Waste Valve Need to Be Attached to Frame of Coach
    No, you won't need to install any additional supports for the Double RV Waste Valves - Sewer Wye - Rotating - 3" Spigot and 1-1/2" Spigot # TR38B. This does not need to be attached to the coach via anything outside of the RV sewer pipes. You will want to use some Valterra ABS Solvent Cement - 1/4 Pint # A05-0303 to make sure it's secured to the pipes.

This wye features a 3" spigot that will slide over your black water line, as well as a 1-1/2" hub that will slide over your gray-water connection.

    Dual waste valves, such as the Valterra # TR38A, are nearly generic by nature. This one has the standard 1-1/2" gray water gate and standard 3" gate, and has a "Y" shape. You should also look at the Bristol # 34466ND13AAR Double Waste Valve that has more of a "T" shape, or the Valterra # T38. Compare what you have on your Freedom Express to these and one should be a match. Many of these connections will have been factory installed with solvent cement an will have to be cut off.

    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.
