Description White 1″ Slip Gunite Air Button is for pneumatic pumps, blowers, and spa packs. Push Air Button is used to turn on the swim current or jets in pools that have an air switch. Push Button version replaces the air button with the chrome top. It allows you to operate pool and spa equipment safely. An Air Switch uses air pressure which is generated from an White 1″ Slip Gunite Air Button to activate a device. Some Spa systems can be fitted to both indoor baths and garden Hot tubs. The main concept of the air system is to inject air bubbles into the base of the bath (spa). This is to form a relaxing bubbly massage effect. Air spa is a simple concept that works very well and has been around for a very long time. Measure the water pressure between the pool pump and the heater unit. If the pressure to the heater falls the pressure switch will send a signal to the heater control board to shut down. Show More Show Less
