Thetford Valves, Repair or replace?

[Gkiesel]

Hello all. 76 Argosy 24' rear bath. Well i dropped the rear of the belly pan to find a shower leak, and discovered that the P- trap had cracked. So I think i found my leak. But I also noticed that i have a hanging drop of water on the outside of my graywater valve. No drip per say, just wet. Thought I should address this while she's opened up. Any thoughts on rebuilding the old valves vs replacing them? The hard part about replacing them seems to be that the factory glued the valve to the 4" outlet pipe! So replacement will mean making all new 4" outlets. Has anyone had good luck rebuilding the valves?Thanks, George.

You may poke your nose into the idea of cleaning the valve first. Perhaps it's gummed up and will not close completely. Some have had success by fabricating a scratch tool to scrape out the valve guide slots. A forums search will produce better advice...


Good luck,

Stephen

George, yes, as described here, using the repair kit is straightforward:

If the internal surface of the valve is scratched, complete renewal of the valve would be preferable, IMHO. With plenty of time, I would opt for complete replacement. However, my Airstream manual states that the Airstream factory just uses repair kits.
