Glass on a Valterra dump valve?
I'm in the process of replacing my original brass Thetford dump valve and need to know,can a Valterra valve (ABS) be glassed on to the tank . Do they have some type of flange available to do this? I know you can do this with a Thetford flange and valve but I would prefer to avoid that because of cost and availability of parts in the future. I have the old valve out of the tank and am ready to fiberglass in a new one.
This is plan "B" for this Valve replacement job. At first I had a machine shop water jet me an adaptor plate and gasket that bolted on to the part of the old Thetford plate in the tank and allowed me to use a Valterra valve ; everything worked out great except I had a leak. Thought it was a gasket problem but come to find out the casting in the tank has a minute fracture line in it , so out with the old and in with something new.
