our flush valves have to be replaced every 3 months or less. once a new flush valve lasted only 2 weeks. Since we have 3 toilets in the house, we spend a fortune on flush valves. We only use fluidmaster brand, which I've heard is the best. We always try the flapper first, this almost never works. We even had a water pressure regulator installed on the main line. What else could be wrong?
