Spa Air Blower
Spas connected with an in-ground pool often have an air blower to provide bubbles through the spa jets. Some spas use water venturi power to suck air through the jets without a powered air blower.
Blowers come in 1HP, 1.5 HP, and 2HP models. Bigger is not better for blowers. Too large a blower can overheat and shutdown or blow the water out of the spa.

Spa Blower Overheating
If there is a restriction in the spa air line, such as a broken check valve, or the blower is too powerful for the air line plumbing the blower can overheat and shut off.
Blower too Powerful
- Replace the blower with a lower HP
- Vent the Air Line - If the blower is too powerful you can vent the air line to reduce the back pressure to the motor. You can install a T fitting and a valve on the T to vent some air. Or you can drill holes in the PVC pipe to vent air. The amount of holes needed will require some experimentation.
