While it does not affect any pump currently installed on an in-ground residential pool, any newly installed pumps that are one horsepower or greater will be required to meet the new energy-efficiency standards beginning January 1, 2012. Dual-speed pumps will be the minimum efficiency for pool pump installations, and inefficient single-speed pumps will no longer be sold.
