I have a old Jacuzzi that is leaking. on the tub of the Jacuzzi is a knob you can turn to chage the air pressure. The knob is connected to a white tube that connects to a black box. the leak is where the white tube connects with the white box. Seems to me it would be a seal that is broken. Any thoughts on that? and where I could get a seal?

Hello Nellie1221,

Your TYPICAL Jacuzzi switch is a FAIRLY SENSATIVE
air-pressure activated button... (common trouble
(in my opinion)).

Quite A POPULAR REPLACEMENT item...
Put up your MODEL of tub on the internet to see
where your parts might be... or get your original parts list

I would look to eBay (and AMAZON) ...
first before going straight to

Yes you can, there should be air induction knobs: Adjusts air flow from off to maximum.

Turn it down.

Air Switch Repair
It sounds like you have a bad air switch located in your motor.
The air switch is what the air hose connects to on the back of the motor or on the box on top of the motor. The other end of the air hose is connected to the air button on the lip of the tub.
This is a latching air switch and when you push the air button it latches to send power to the motor. When the air button is pushed again it opens the latch in the air switch and stops power going to the motor shutting it off.

IF that is the one I recall, the switch is not connected to the tub. When you press the button, it sends air pressure to the switch under the tub to activate it;. You need to check the tubing and the switch

Surging is caused when the pump doesn't have enough water to push to the jets. this is usually a problem caused by air being drawn into the suction of the pump.
take a look at the jet(s) facing the suction cover.
I have seen cases where the water with the air mixed in causing bubbles gets sucked into the suction of the tub and causes the surging because the pump is pulling in too much air.
try rotating the nozzle of the jet facing the suction away from it. point it another way. turn the air control knob closed and see if that is the problem.
the only other issue that could cause this 'surging' problem is a leak in the suction line and could be the source of the water you see under the tub.

The Magic Touch system has been discontinued by Jacuzzi Whirlpool.
You will need a new air switch kit.

If the Pump will NOT turn OFF, then the switch, must have failed, in the ON position, I suspect you will need to replace it.

no there is no solutions for plugging off the jets so the water doesn't go in them. you will have to pull the tub and repair the lines. no access panel just means you have to dig in!

Your Jacuzzi should be connected to a large GFI breaker. If it pops as soon as you turn something on, there is an imbalance between the legs supplying the power to your device. When my (small "J") jacuzzi (at about age 15) did this, I discovered a small leak that had dripped onto the circuit board and had left a deposit causing a "short". I was able to clean the deposit off of the board physically, I fixed the leak and return my tub to service.

The GFI is very sensitive and for good reason. It protects you from dangerous electric voltages, even though the danger is low.
