Off and on, my Jacuzzi brand hottub has been giving me an "FL" error. The code is on Solid (not flashing). When it happens, the tub won't flow, start, heat, or anything. Thumping the tub used to fix it, and now, only slapping my hand over one of the output nozzles does it.

I've been led to believe the pressure switch is bad, and I've finally gotten around to draining the tub and removing the old switch. My problem is that I can't find an exact match anywhere. Will a generic replacement do?

The switch label show "Balboa 1 PSI - 30409"
A second label reads "Pressure Switch 1A 1.0 PSI GRN"

Would this switch be a good replacement part:

That pressure switch can be replaced by virtually anything in the lineup that uses the same threads.

I also have the flo problem on my jacuzzi. Can you tell me approximately where the pressure switch is located, and will the tub need to be drained before the switch is changed?
