My wife and I decided to open the pool this year ourselves. We have only owned an inground pool for 2+ years and would still consider us novice level. The returns continue to show signs of problems. (inconsistent pressure and bubbles) We have an inground 22k gallon pool with a liner, 1 skimmer, and DE filtration system.
1. Released air in filter several times.
2. Completely cleaned DE flter.
3. Garden hose in intake hole of pump to clear any possible debri stuck in impeller
4. Closed skimmer intake in skimmer box leaving the drain for intake. Nothing was reaching the pump. I suspect this is the problem. Thoughts on what I can do next to narrow down the problem?
