The Pentair check valve after my cartridge filter failed. Now, I had a pool equipment rebuild 3 years ago (completely unnecessary but that's another story) so I know the valve was changed then. I am planning on putting in a new flapper today. When I opened the valve yesterday I found that the spring had rusted so it was not closing all the way anymore. The filter was getting a lot of air in it and this is the culprit.
Is there anything to do to repair this rusting without replacing the flapper? I ask because I now have several of these in my system and I am thinking I'd better maintain them all. This will be expensive.
I am confused as to why this company put in spring-loaded valves because they were supposedly replacing my plumbing to minimize the head through my pipes. Spring-loaded valves add a lot of head by design. I now feel that they should have used a flapper-style check in a vertical orientation. Oh well...hubby says wait a little while and we will redo it all right again. We are saving $$$ but only because they also installed a newer more efficient pump. The plumbing redo was a scam as far as I am now concerned.
