I have a 30000gal in-ground pool with heyward pump and filter. The pool as two skimmers. The skimmer on deep end seems works fine but the skimmer at the shallow end of the pool has started to suck all water out of the skimmer basket down the drain until it starts sucking air in. The basket area wont fill with water. Pool water level is full. Pressure on filter is fine.
What is going on? Thanks
