hey guys, ive got an inground pool, and as i fill the suction line to the skimmer, thru the pump, it fills the pool w/ water instead of coming back and overflowing the pump to get a prime. i am new at pool ownership, this is my first season ever. i caught the tail end last september when i bought my first home, and quickly had to close, but when i filled thru the pump to get prime it only took a few seconds to overflow, now it fills the pool instead of overflowing the pump for a prime. i only have one skimmer and one main drain, oh and the same goes for the main drain if i shut the skimmer valve and fill the main drain it will just fill the pool instead of filling up and overflowing the pump. any ideas!!!!
