My husband and I spent some time cleaning up our pool after several days of rain and used the vacuum to get a bunch of debris off the bottom of the pool. After doing this, we noticed the pump wasn't working as well as it typically does. The pressure was down at about 5 psi and there was a lot of air in the pump and not nearly as much water as we had seen moving. We couldn't find any air leaks so we called our local pool place. The guy came out and looked for any leaks with the pump, but didn't see any. He also stuck his finger into the pump and I think he told me he was checking the impeller to make sure it wasn't clogged with leaves or debris. He couldn't find anything wrong and said we probably had a crack in a pipe. He said they couldn't do anything about it since we have a gunite pool and gave the the name and number of a place that could fix it. Is there ANYTHING I can check before calling this other place? I'd hate to spend a bunch more money if I don't have to. I'm just sick because the guy told me it would probably cost a couple thousand dollars to have this fixed.
