I had a company install one of these a few months back for my in-ground pool. They obviously didn't seal the top valve correctly because I can hear it releasing pressure when the pump is running. Where they supposed to use PVC for the pipes leading up to this unit? I just find it funny as it is hard to remove the valve from the top in order to replace the gasket. I found diagrams of the above ground Hayward filter with the top valve and these had flexable piping leading to the top , I'm assuming so that it's easier to remove valve. Please advise. Thanks, Rick
