AIR VOLUME CTL DEEP WELLS; STANDARD WITH 1/4"GAGE TAP

Application

Water storage tanks in residential water systems rely on a volume of air in the tank to provide system pressure, making it important to control the amount of air in the tank:

• • Too little air in the tank results in rapid pump cycling - a problem common in shallow well systems (less than 7.6 m [25 ft] deep).
• • Too much air in the tank results in air entering the distribution system — a problem common in deep well systems (more than 7.6 m [25 ft] deep).

Repair Information
