Just fired up our 0.5 HP Northstar for the season. Initial startup was fine because it was priming, but once I turned the pump off to do some work, then turned it back on, it makes a screeching noise for about 30 seconds. The noise then goes away and the pump runs without issue (primes, little to no air in the pump basket, etc)
Any easy way to figure out if its a motor or impeller issue? I was thinking motor since it happens at every startup, figured once the noise went away if it was something in the impeller area it would be "away" for good.
Everything on it is original, so its all now about 12 years old.
And if its the motor, any suggestions on replacement? Dont really have the time to deal with replacing bearings and would like to go to something more efficient anyway (2 speed motor replacement or even a whole new 2 speed pump). Need to consider what flow rate is required to get the AutoPilot to kick in, would be nice to have it operate normally even on low speed so I dont need to worry about switching.
Thanks in advance.
