SOME ASSEMBLY REQUIRED – The Hands-On Handbook 4 5 MODERN EFFICIENCY Smart Flow


A modern pool pump such as this IntelliFlo model from Pentair responds nimbly as needed. These pumps use an exclusive permanent magnet motor (used in hybrid cars) in place of a traditional induction motor. The unit has variable speed capability, digital controls and proprietary software that allows custom programming of optimum pump speeds for specifi c tasks, including fi ltering, heating, cleaning, spa jets and waterfalls


Program the new pump. Calibrate the new pump’s fl ow to obtain adequate circulation at the lowest possible motor speed for each task— fi ltering, cleaning, backwashing, operating water features and so on. Consult a pool professional or documentation from the manufacturer(s) of the other equipment for guidance.


Measure the energy consumption of the replacement pump. This allows you to determine the actual energy savings achieved as a result of this retrofi t. On typical installations, variable speed pool pumps can skim and fi lter water while drawing less than 300 watts.


COMMON ERROR Overpowered System


The most effi cient pool system uses the lowest possible fl ow to maintain fi ltered, sanitized water. Determine if the fl ow is in the ideal range by looking at the skimmer weir. Water should be fl owing at a rate that consistently pushes about 1/4” of water over the weir. If the weir lays fl at, the pump is working too hard; i.e., fl ow is too high. The weir door should move freely.
