Chuck L Posted January 21, 2011 Report Share Posted January 21, 2011 I have an older (I believe that it is a late 90's model) Cal Spa 3 man hot tub. We got it free and installed it about 3 months ago. Up until now, everything has operated satisfactorily (installed new heater element, repaired a few jets, etc). However...now the pump will not shut off! It is (as, I believe, most are) controlled by a vacuum/pressure switch for the on/off as well as an adjustable pressure air intake. Is this, possibly, caused by a defective pressure switch or am I looking at something a bit more involved (and costly)? Any input would be greatly appreciated!
