Thank you for your reply.

I had assumed it was just a matter of impeller rpm. The reason I suspect I need a bigger pump is this. The suction line from the pump is split by a Jandy valve into a pool cleaner line and a skimmer line. The only time I can balance the two lines to get adequate performance is the first few weeks after the filter (Pentair Quad cartridge DE 60) is cleaned. Most of the time I have to run 85% of the suction to the cleaner and the skimmer hardly works.

Do you think a bigger pump would solve my problem? I was thinking of going to a Pentair WFE - 4.
