My wife and I have been frequently replacing the o-ring on the lid of the strainer basket going into the pump. The first o-ring installed (Hayward Pump) lasted a couple years. We are now replacing 1 a week or more. No changes to our water and all chemical levels are good. We thought maybe using Vasoline v.s. pool lube was the problem, that doesn't seem to be it. We have removed the water, cleaned the lid, replaced the o-ring (again), used both Vasoline and/or tube lube and same issues. Any thoughts or troubleshooting ideas? The local "pool" stores don't seem to have a clue.
Thanks in advance!
