I have a Sta Rite MPRA6E-147L 1HP pump on our inground pool. It is about 12 years old and has been giving me issues for the past 5 years or so. Every spring, I have to open it up and physically spin the impeller, because it seizes up during the Minnesota winter (all water drained, etc...). It has gone through a couple capacitors in the past 2 years. This spring I opened it up and spun the impeller, but when I put it back together, it won't spin. I noticed that the impeller itself doesn't seem to sit center in the hole of the diffuser. I found orange, crusty build up on the inside of the diffuser hole and I tried to sand some of it out of there.
I am thinking that it might just be time to retire the thing, bit the bullet, and buy a new pump, unless I hear otherwise from the wise people here. If I should replace, what would be an appropriate replacement? We do run a salt system and we have an booster pump for the cleaner (same age as the Sta Rite and has started to cause issues as well - I believe I replaced a capacitor last year as it began to hum and not start). The pool doesn't get a lot of use and only a couple days a year has a full load of party guests. Everything set up there is 110 (Heater, booster pump, regular pump, chlorine generator). There are no timers or anything. (Pump is normally turned on constantly.) I am not an electrician, but I am not sure there is any extra "flow" out there (for example for 220 instead of 110). I had my father, who does electrical stuff from time to time, look at it once for adding an outlet out there. He had indicated that we probably wouldn't be able to.
Your thoughts and suggestions would be greatly appreciated!
