    Blower switch works intermittently

    I have one of those push button blower switches on my hot tub that works on air pressure. You press the switch once and the blowers come on just like they should - every time. Problem is, once the blowers are on, the switch usually won't turn them off. I usually press the switch 20 or 30 times, and one time it just finally works.

    I removed the switch to test it and it blows a little puff of air. Made sure the hose was connected to the switch properly, too.

    What could be the problem?

    It's probably the diaphragm switch sticking or the tubing leaking.
