I have an inground pool for the last 10yrs with no problems. i noticed the other day the pump wasnt pumping. i found the defuzer{its a hayward} was warped and the o-ring was warn. I also found that the impeller we stripped on the motor so i replaced all of these items, defuzer,o-ring seal, impeller, ceramic seals at motor, pump strainer and pump strainer lid o-ring, After I installed all of these items the motor turns on and spins but I still get no pressure building up, PLEASE HELP.... I am going crazing with this thing
