The only label on my pump is on the motor and it is an A.O. Smith Motor 1Hp It is at least 5 years old
My pump is making a noise it never made before, if I had to guess I would think it was a bearing squeal. It is not all that loud or irritating "Yet". Just a bit worse than a hum. But definitely not the way it sounded before.
The pressure may not have changed at all, but it may be lower. It is at 14psi and everything else is cleaned and backwashed. My system normally runs at 15-18psi. When the filter needs a backwash it gets to about 23psi. Anything lower than 15 (usually 10 -15psi) tells me to clean the pine needles out of the impeller.
Can the bearings be lubricated?
Is this the beginning of the end for my pump?
Can I ignore it till it gets too loud to tolerate?
Is there something else I should check or suspect.
Thanks for any help
