This all happened after the pool company came out and vacuumed the pool floor. I now have bubbles in the pump basket. They go away when I shut off the skimmer line. They go away randomly sometimes and then when I mess with the valves, backwash, clean out pump basket they return. They go away sometimes when it rains. I don't see any air going through the returns. I am not losing any more water than what I am used too with the pump off and the pump on. I'm stumped. I called the pool company and he said if its not losing a lot of water, who cares. He also told me that it would be late in the summer to come look at it. Pool companies in my city (Lincoln, NE) are always booked up for the 3 months of the pool season. I have also tried to put a hose with a towel in the basket to help if it was a clog and still no luck. I'm stumped. I'm very close to filling in the pool, I had a green pool until August last year. I'm exhaused with the pool and the lack of help from pool companies when I need it. You guys bailed me out from the green pool last year, so I am here again.
