Hello all - first post from me. I saw other posts similar to this but wanted to ask a specific question about testing a flow switch. I recently replaced my pump motor (just bought the house and motor had a bad bearing and was extremely loud). New pump working great, no leaks. However, since I replaced it, every once in a while my system says "Chlorinator Off - No Flow" or "No Flow Filter Pump". My suspicion is that I stepped on something or kicked something replacing the pump and broke the flow switch. At any rate I did the following as tests:
Unplugged the switch from the panel - same issue (obviously - no way for the loop to close)
Turned the flow switch the opposite direction (to make sure I did not wire pump backwards and reverse the flow) - same issue
The switch connects to the panel with an RJ-11 telephone jack. So I took a spare telephone cord, spliced it into a loop (to complete the circuit) and plugged it into the panel where the flow switch would normally plug in. Since I did that it's been running like a champ - pump and chlorinator. I have good flow, my water fall feature is working and the filter pressure is good. Is this proof that the switch is bad or should I do more testing? I ask because the switches are pretty expensive ($100 +) so I don't want to buy one if it is not my problem.
Appreciate this forum very much - I have learned so much already!!!
