I have been in operation for 3+ years now and 90% of my BF valves are Inoxpa that came with (or were purchased later) the system from Premier Stainless. I have not seen any of them leak, but many of them are getting awfully stiff. I have read every thread I can find on the PB site regarding the seats, and replacing them, but would love some advice on what is ultimately the catalyst to do so. Leaks and visual tears are obvious, but I would rather replace before any leak compromises anything in the process. As for them getting stiffer -- all it really means is that I get them a little wet and they are easier to open/close. But I am wondering if I should just pull the trigger and at least replace all the seats in the hot side process flow.
Any advice appreciated.
