Expert Reply:

The difference between the three Valterra Double RV Waste Valves referenced in your question has to do with their fittings, specifically their use of hubs or spigots. Basically a spigot (also referred to as the "male" fitting) will go inside of a hub/socket while a hub (female) goes over a spigot.

The particular waste valve you need will be specific to your application and existing setup.

The Valterra # T81 has a 3 inch hub and a 1-1/2 inch spigot.
The Valterra # T81A has a 3 inch spigot and a 1-1/2 inch spigot.
The Valterra # T81B has a 3 inch hub and a 1-1/2 inch hub.

I have attached a couple short video reviews on these assemblies that you can check out as well.
