Hayward Northstar 1.5 HP.
Started to shock, left pump running overnight. We'll call them needles, but these are much finer; had matted the area around the intake on the pump basket. This was probably a water-proof patch about 3x4 inches.
The pump was causing waves.
Turning it off and cleaning the basket produced a surge action on trying to prime.
I have it open - no needles or other obstructions. Motor turns freely.
The white plastic part ID'd in the manual as SPX0321R Impeller Ring (the guy in the dis-assembly video I found refereed to it as "wear ring") shows a scorch ring and about 20 small rotational grooves on the inside.
Before removing the impeller and risking damage to it:
Is it possible that the damage to the ring could be all there is to the problem?
Having no way to test short of re-assembly and installation, I'd like some idea of probability of finding the problem before buttoning it back up.
Beyond this. only the shaft seal is replaceable.
The obvious thing is to buy the impeller kit and throw it at it - but my back still hasn't forgiven me for pulling the motor...
thanks as always
