A pool-pump timer is useful only if it actually reaches the purchaser. DOE's January 18, 2017 direct final rule addressed that handoff for integral cartridge-filter and integral sand-filter pool pumps: units manufactured starting July 19, 2021 would have to be distributed with a timer, built in or shipped separately with the pump. [2016-31666][2016-21310]

The defined timer automatically switches the pump off after a run of no more than ten hours. The text also addressed pumps supplied with freeze-protection controls. They would ship with protection disabled or with user-adjustable defaults capped at 40 degrees Fahrenheit, one hour before checking temperature again, and half the maximum available motor speed. Those are delivery settings, not evidence that a particular household saved electricity. [2016-31666][2016-21310]

An earlier September 2016 proposal explains a different part of the policy: measuring pump performance through a weighted energy factor, or WEF, relating water flow to input power at different operating points. Its proposed testing scope excluded the integral-filter categories covered by the timer provision. A timer requirement and a performance metric therefore should not be presented as the same feature. [2016-31666][2016-21310]

The January rule scheduled May 18 effectiveness and July 19, 2021 compliance, subject to withdrawal for qualifying adverse comments received by May 8. It did not order immediate household replacement. These related DOE records explain product delivery and historical measurement design, not independent evidence of lower bills or the final adoption of every September testing detail.
