Easy to install and Easy to diagnose bad flow sensor
Hot tub was showing 3 flashing lights, read up on type of switch (open) . Should read 1 with ohm setting… it did not. 5 minutes to remove and replace. This is not a stock item at any of our hardware stores in town. Very happy with my purchase.

Great sensor
Worked great to fix my hot tub . The oem one was way too expensive , I liked the fact that you can adjust the pressure trigger.
