Hello to all,
I just started up my pool pump on Saturday, and found that the pump was seized up. Basically producing a fairly loud hum, with the motor getting very hot. I de-installed the pump with the intention of getting it repaired or replaced. But after I had the motor off of the pump head, I attempted to spin the shaft. It was "stuck" to some degree at first but did spin with some resistance. And began to spin more freely the more it was spun. So, I re-installed the motor to the pump head, rewired and the pump seem to run fine, after an initial 2 sec of squeal. I did a backwash, mostly due to just replacing the sand in the sand filter, and it seemed to function ok. I did a rinse the then to filter. At this point, I need to say that I also have just installed an Auto Pilot SWG, which may or may not be relevant. So, while on filter and producing 16lb of pressure, bearly any water gets jetted to the pool. Just a very little. I do see a small amount of water going through the bypass on the Auto Pilot manifold, and I guess is the small amount getting to the pool. I'm not sure what my issue is. Could the pump be bad and only running at part speed? I "sounds" ok, but ??? Any ideas?
