Hey all (can't believe this is my first post as I've been a lurker since the old days. anyway),
so I have on old Hayward pump with an ao smith 3/4 motor. Not sure how old it is but has to be more than 10 since I've had the place 8 years and it was not near new when we bought the house. Just this morning I heard it going into an overheat/shut down cycle with a short interval, like 1-2 minutes. After it cooled down and I restarted just to check, it was clearly laboring and flow was super low. Not likely the start cap because it was replaced not that long ago and the pump was starting. I still have not checked the run capacitor or voltage (from loose wire or failing timer--we did have a heavy downpour that I'm waiting out). Nor have I had the chance to hunt out any flow restrictions. Anyway, I'm assuming that the motor is failing after over a decade of service in the south (southeastern Louisiana; pool is essentially never closed, pump runs every day, although on timer, so let's say 10 hrs a day); in fact even if it turns out to be wiring or capacitor related, it might just be that time to undertake replacement, right? So I guess my question is whether I should look into re-doing the whole pump vs just the motor (all pump parts are original, impeller, etc. I've done some o-rings and seals over time, but that's it); and then the question is variable or 2 speed motors vs current single speed on timer options. I guess 3rd question is just seeking confirmation of my feeling that it makes more sense replacing than repairing a unit well into its 2nd decade of pretty steady service. I mean I pull things apart all the time and rebuild from scratch, but by the time I do bearings, a possible run capictor, seals and so forth, I'll still have old windings that have been in service exposed to elements for over a decade and have this recent bout of overheating . Thanks in advance.
I poked around but did not see a sticky or other general pump guide thread. Did I miss one?
pool is pretty small, I've estimated around 10,000 max, probably a little less, with only 1 skimmer
