Hello, I purchased a home in August with my first pool, owner seems to have taken great care. I came home the other day to find significant air coming out of the return lines, whirlpool action in the pump basket, no pressure in the filter, reads 0. Water level is perfect, and pump is returning significant amount of water to the pool, just with a lot of air. The pump basket isn't filling completely with water.
From my reading this points to a suction side leak? Could this be a clog as well? My system is fairly simple, see pics below. We've also had cold weather in south texas, so weather in the 70s one day and lows in the mid 30's the next, not sure if that could affect pipe fittings. You will also see plenty of small leaves I'm the pics, they may be an issue as well. Both skimmer and pump baskets are now completely clean.
Thanks for your help as I'm going to try to tackle this myself. The company my home warranty provider sent out seems to be trying to get into my pocket. They are pointing to an underground leak. I just don't see how that much air could be sucked from underground.
