We just purchased a home with an in ground pool. The pump cannot be shut off without losing prime. Also, lots of air bubbles are visible at inlet jets. Skimmer seems to be working ok and pool doesn't look like it's losing any water from a leak. Watching the skimmer sight glass it looks like the system is gulping air from some place. The skimmer will be full one minute and then the water level in the basket will go down with lots of bubbles noticeable and then eventually fill back up with water. It keeps repeating this process.
Running the pump constantly cannot be good on the motor, and I don't even want to think about the utility bill this first month in our home. Any help would really be appreciated.
