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.
Vendors for air blowers include:
Troubleshooting
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.
Water Going up the Air Line to the Motor
- There should be a Hartford Loop and a check valve in the air line to prevent water flowing up to the blower
- New installations have had the air line and water lines to the spa reversed causing water flowing up to the blower.
Tips
- The water line and air line run separate to the spa jets and are combined by two inlets at the back of the jet combining the water and air
