Working to Fix Play Structure Pump Issue

All, we are working to try and figure out what is causing the pump to the play structure in the kid pool to trip off. It had been tested for a couple hours last year after the pump motor was replaced and again before we opened the pool this year and we had no issues. It is strange that it will run for 4-5 hours before tripping off and that also makes it more difficult to figure out what is causing it. We are having different contractors check on it this time and hoping they will be able to figure out the issue. We are not currently running the pump as we are worried whatever is causing this could burn up the motor. I’m very sorry for the inconvenience and will keep you updated. This is obviously very frustrating and we appreciate your patience.
