I bought my pump 11 months ago and it's worked just fine with no problems until today. I came home from work and found the clocks flashing as if we had a power outage. The power was on and the pump was making a very loud noise it hasn't made before. I checked and I had normal water flow and the pressure was normal. Other than the noise, the pump works just fine. The noise doesn't sound normal.
Since they say the problem is likely the last thing you did, here's what I've done going from recent past to distant past:
Power outage today
Replaced the pump basket with a new, tighter model last weekend
Installed an Intermatic T104 mechanical timer about a month ago
Installed the pump last September
Here is a link to a video of the pump running: http://www.youtube.com/watch?v=gilM2ofdN54
I'm going to call the PS where I got it tomorrow. Does anyone think it will be a problem to let it run tomorrow?
