I need new seals for my dump valve in my 1973 argosy. Nothing at the RV store fit. Any Ideas ? I called Thetford themselves but got no luck.

Plastic shrinks in time. "IF" you found the seals, and installed them, you will spend a bunch of time, that might last a few months.

The best solution is to replace valves that are 38 years old.

New valves will probably last another 38 years.

And, the new valves will save you some headaches and gray hair.
