Great question.

I can help you get what you need but I will need more information.

Unlike vehicles RVs are not at universal and variations are common place. The best way to find out is to take a picture of your current waste valve and send it in a reply to this email, then I can help find the right one.

The most common styles of waste valves are the following:

Double RV Waste Valves - Sanitation Tee - Rotating - 3" Hub and 1-1/2" Spigot # T18C.
Double RV Waste Valves - Sewer Wye - Rotating - 3" Spigot and 1-1/2" Hub # TR38A.
Double RV Waste Valves - Sewer Wye - 3" Fixed Hub and 1-1/2" Rotating Hub # T38.

If you are not sure what you have I can identify it with a few pictures of your setup.
