Newbie here when it comes to pumps.
I noticed this year that my pump doesn't seem to pump quite as high flow as it used to, but it still pumped 12 on the gauge and I would backwash when it got to 15.
However, today my pump started making a lot more noise. Could a bearing be gone? It still pumps and seems to prime the line OK, but it clearly has less suction when vacuuming. Baskets are clear. Also, the motor seems a lot hotter to the touch.
Hayward 3/4 HP superpump at least 7-8 years old, maybe 15. SP-1605-Z1-M, 230 V
Is it worth it to try to change to a new variable speed motor, or replace the whole pump? How can I be sure there isn't another problem with my sand filter/other pipes?
