We have just had the pool resurfaced. Now I am getting a lot of air being sucked into the pump. It is coming from the input pipe on pump. I have two skimmers and a bottom drain connected to the pipe coming from the pool to the pump. I just shut off the bottom valve and then the pump sucked almost nothing but air. When I shut off the skimmers one at a time nothing changes still sucks a lot of air with the water. The water is over half way up on the skimmers. The company that resurfaced the pool did chip around the bottom drain.
Could a bad valve seal at the plunger to open and close it pull in this much air.
Any tip on troubleshooting where the air is coming from
