20000-360005 B0052400A water flow switch used in many Heat Pumps and other appliances. Semi-universal fit where 3/4″ thread is used. Used by Hayward, Sensaheat, Madimack, Astralpool, HeatSeeker, Sunlover, Oasis, Zodiac, Phnix, SpaNet and many others.
Notes:
- Each heat pump manufacturer has different plugs, so you may need to cut and join the two wires. Polarity does not matter.
- Blue part in photos is a thread protector they sometimes come with but is not used.
Most fail due to water balance issues or bromine.
