Hi Joe,

So you just need to know if the valve you are replacing slid over your pipe or into your pipe, and I'll go over how for you.

If both ends of your waste valve slid into your sewer pipe you will need the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Spigot to 3" Spigot # T40A.

If both ends of your waste valve slid over your sewer pipe you will need the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Hub # T40B.

If one end of your waste valve slid into a pipe, and one slid over a pipe you will need the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Spigot # T40.

To install these the only other thing you will need is the Valterra ABS Solvent Cement # A05-0303.
