Hello Debi,

There is 20 air jets on this tub, see link below showing the jet layout.

There will be a plug coming out of the back towards the center of tub that you would plug into a 15 amp GFCI receptacle.

Air Blower is Different than a water pump. Air Blower mixes air with the water to create
soothing bubbles. A Water Pump circulates
water through a piping system and exits through water jets.

The air blower is a low maintenance item but if ever you
needed to address an issue with the blower, access is pretty simple. You would just undo the nut from the drain basket to the drain
pipe, remove the fasteners that would be used to attach the metal clips to the floor that are
on the pedestal, then pick-up and move the tub and pedestal. You would then just turn the tub over and you
would have full access to the blower and the plumbing, as it is contained within the cavity of
the pedestal.

For your convenience I've also attached the specification sheet for this tub.
