I currently have a WhisperFlo 1.5 full rated pump that I would like to replace with a 2 speed pump. Going through Pump Education I have a feeling our current pump is oversized (no surprise there).
You can see in my signature that we have a 35k pool with a TA60D sand filter. According to Pentair the max flow rate through the filter should be 60 gpm. The pad is is plumbed with 2" with 2" headers for the suction and returns. The returns are three separate 1.5" runs (60') and the suction includes 2 spearate 1.5" (40') runs for the skimmers and 1 1.5" run for the main drain (40' length 8.5' depth). No solar or water features.
Looking at pump curves I am not sure what I should be using for head loss of our system. I think we can use a 1hp 2 speed pump but am not sure what the most efficient pump would be.
Thanks for any help.
