I went with Pentair Whisperflo EE (Energy Efficiant) WFE-4 pool pump. You must check pump model specs, not all of them fall into the EE specifications.

Since your in California, you may qualify for a rebate on a new pool pump. Info below. Had I known that they have a $250 rebate on qualifying two speed pump, I would have gone witha 2-speed pump. Pool store gave me incomplete info.
