I own a 12000 gallon pool chlorine pool with plater.
Hayward filter s244t sand filter
Emerson 1081 1.5 hp pool motor
Filter is 8 months old and have no idea how old the pump is. Seems to work fine and runs quietly... until I vacuum the pool. It will sound the same but slowly lose suction until it's borderline useless. The motor never stops running though. I'll turn off the pool filter and wait 30 seconds then restart and it's good as new for another 5 minutes or so of vacuuming.
No bearing issues or really any probelms until I fired the pool guy and used a 40' Helix vacuum hose, Hayward skim plate, and Hayward SP1068 Vacuum Head myself.
