Hi: Since June, I've noticed when my motor is off, the Pool filter pump water level drops. When I turn it on, it takes about 30 secs for the pump filter to fill up. While the pump is running, there are air bubbles in the filter pump I can see. Prior to June, the filter pump water would be full, and no signs of air. I replaced the rubber gasket on the filter pump lid, replaced the rubber gasket on filters. There is no sign of water lead anywhere around the equipment. Last month, I bought a new motor from inyopools because the one I had stopped working. I'm not sure the low water level in the pool filter when turning it on was the cause the motor to go bad. I replaced the motor using the video instructions from your website. The motor is much quiter and working like a charm, however, I still have air bubbles in the Pool Filter. Any ideas why this is occurring?
