Recently acquired a 1974 Argosy 24 and doing a full rennovation. Need to replace both dump valves. If it's recommended that I replace the old Thetford valves with new ones, how do I determine which Thetford valves I need? Or can I replace the old Thetford valves with Valterra valves? If so, which valve(s) will work? I appreciate any advice. Thanks!
The older stile Thetford valves are very good, but are becoming harder to find and are quite expensive. If I were re doing the valves on my Argosy at this point, I would probably go to the Valtera ones. Less expensive and easier to get fittings for now and in the future.
I can't tell you what valves you need however. My comments are just my observations of what and why I would change.
