Mdh Posted May 14, 2021 Report Share Posted May 14, 2021 I have a Jacuzzi brand hot tub model J-355 and need to replace the flow switch. Where can I find the flow switch at? I purchased a replacement one but can't find anything that remotely looks like what I have. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted May 14, 2021 Report Share Posted May 14, 2021 It is usually just after the heater and before the ozone injector. To the right of the control box near the top. You can track the wire back from the circuit board to find it. Post a pic of the equipment area. 1 Quote Link to comment Share on other sites More sharing options...

CanadianSpaTech Posted May 14, 2021 Report Share Posted May 14, 2021 Check for a pressure switch on the chrome heater tube. Either inside the pack or in behind the pack Quote Link to comment Share on other sites More sharing options...
