ABSTRACT:
A modular air gap device adapted for selective insertion into an associated faucet body and comprises a base, an inlet nipple defining an inlet passage and an outlet nipple defining an outlet passage. The inlet and outlet nipples project outwardly from the base in a first direction. An gap structure is connected to the base and projects outwardly therefrom in a second direction opposite the inlet and outlet nipples. The base and air gap structure are adapted for receipt within an air gap chamber of a faucet body. The air gap structure defines a flow path having a first end in direct fluid communication with the inlet passage of the inlet nipple and a second end spaced from the outlet passage of the outlet nipple so that an air gap is defined between the second end of the flow path and the outlet passage. A faucet including the air gap device defines a vent for venting the air gap chamber.
