I have an '89 jayswan 29' with a thetford starlite toilet. I ordered a replacement base/valve assembly from amazon. When I received it it said for toilets manufactured after July 1990. I don't know if this piece will work. I don't want to try to install and not be able to return it.
What are my options here? The metal pieces on the original are all corroded and stick so the water will continue to run with the trap door closed. Then a big mess!
