Question:
Will this flush seal fit a Thetford Aqua-Magic V
asked by: Fred
Expert Reply:
Hi Fred, these seals can be tricky for sure.
The seal you need for the Thetford Aqua-Magic V is part # TH34FR72JK. The options you mentioned part # TH43RA are for different toilet models, so they would not fit or seal correctly on the Aqua-Magic V. Going with the TH34FR72JK ensures you get the right fit so the bowl holds water properly and you avoid any leaks or having to redo the job.
What RV is your Aqua-Magic V in, and do you enjoy tackling these kinds of DIY fixes?
