Expert Reply:

When installing the Valterra Eccentric Tank Reducer # T1041-1 to your existing tank with a 3" opening you will just need to use some ABS solvent cement like # A05-0303 for the attachment. This is also what you will use to add the LaSalle Bristol Cable-Actuated RV Waste Valve # 34466N11AB48GMA to the fitting.

You will want to coat the outside AND inside of each fitting with the solvent before connecting the components. What this does is actually cause a chemical reaction with the plastic that causes them to mold together. You are essentially welding the pieces together when using it to create a permanent seal.

I have attached a short video below (skip ahead to around the 1:30 mark) that demonstrates this process pretty well.
