I have the Jandy FloPro FHPM1.0-2 (2-speed pump....I also have a 2-speed timer) at it has been working great for nearly 6 years. However, in the last few weeks, it seems like it is working much harder than usual and is not moving nearly as much water. I would estimate that the pump is moving about 30-40% of the water I used to see (and this is on high speed).
I tried backwashing, thinking the filter was plugged - but the water coming out of the backwash line is much slower than usual. So, I moved the multi port valve to recirculate (attempting to bypass the filter) and the pump is still running slow.
I used to have the Jandy valve set about halfway between skimmer and Polaris. Now, it has to be 100% to Polaris to make the cleaner run.
The motor sounds fine, though I can tell it is working harder than usual. Does anyone know what might cause something like this?
When I look through the clear lens on the filter basket, it seems like the water doesn't 100% fill this area anymore. It is maybe 80-90% full. This has not changed in several weeks - even after I clean the basket, it returns to this level again.
Thanks so much for your help!!
