Air Control Valves
More air means stronger jets!
Air induction controls (AKA Comfort Controls) regulate the "air to water mixture" coming out of each jet. The more air the greater force of the jet. Once in awhile these air controls need some TLC. The beauty of the folks at Watkins Manufacturing is that they still make available parts for spas that date back to 1980. No other spa manufacturer is this cool!
