The Polaris 380 booster pump sounds different, the tone has gone up higher. It is not squealing, but 3 or 4 more steps up like this and it will be.
So, is it possible to check anything out prior to replacing the pump motor?
Is there any reason to consider replacing the entire pump instead of just the motor?
Local pool store has suggested that I bring it in for a free check up, replacement motor plus seals will be $193. New pump would be $299. I don't know the particulars of either as for size or such, I am guessing there is not much choice to be made as to any upgrades for a Polaris booster pump for 380.
