Expert Reply:

Yes, the Valterra RV 3 inch Waste Valves, like part # T50, are designed to fit standard waste fittings. The part that I referenced is just the regular waste valve. If you are looking at a specific design, you can find a variety of designs on the linked product search page.

You will want to make sure to use Solvent Cement, like part # A05-0303, for a complete and secure installation.

My Bristol 3 inch waste valve will not open when I pull the handle out. How do I drain the waste tank so that it can be repaired?

Are you able to see if the waste valve actually moves? It could be that the cable connection is a little loose and just tightening it up will get the valve to move. Worst case scenario would be having to open up your sewage with it still full.

@JonG the handle pulls out of the valve ‘box’ but the ‘door’ inside is not connected. Where is the cable connection?

@MargaretC Some waste valves have the handle located elsewhere so there is a cable that is used to open and close the "door", like part # 34466N4BB72GM. If yours just has the handle then this could get a little messy, not going to lie. I saw a few people tried using a 2x2 and lightly tapped on the "door" part of the valve to try and break any seal that might have formed, and then they used needle nose pliers to open the door from where the handle would normally attach to the door.
