The missus told me in the morning she heard strange noises from the pump so turned it off.
This was actually about the pump not being primed and also likely that there was no flow. As for no flow, After doing some checks (listed below), I turned on the pump. Because I had the volute cover off to check the O-ring, the pump pushed out the air and then started what looked like a good priming flow and then the flow just totally stopped. Note pump has max speed of 3450 rpm and I typically use a 2900 rpm priming speed and have never seen trouble.
I can't think of an air leak causing this since there is a very good flow at first that actually goes down to zero after 10-15 seconds.
What am I looking at or searching for?
Checks:
* pool skimmer basket had no debris that would cause a block
* pulled skimmer basket off and a cover to check for any other blockage: none
* pool bottom drain clean (note we have a pressure-run Polaris cleaner working all the time during the pump runs)
* pump volute basket clean
* no backpressure reading on gauge of cartridge filter
15'W-30'L plaster (gunnite?) 3'-6'D 12,000 gal
Pump: Pentair SuperFlo VS 340021
Cartridge Filtered
We pay someone monthly to come out weekly to control the chemistry (even though I am myself a chemist ), clean baskets, and control the cleaning of the cartridge filters (he says twice a year)
