3/4 in GHT Vacuum Breaker

The Watts 8BC vacuum breaker fits a 3/4 inch garden hose thread connection and is built from chrome-plated brass with a rubber seal. It prevents back-siphonage in residential and light-commercial plumbing systems. The unit meets ANSI A 112.1.3, ASSE 1011, ASSE 1001, cCSAus B 64.2, IAPMO and UPC standards.

Sustained-pressure behaviour

Rated for a maximum working pressure of 125 psi, the breaker maintains its seal during continuous supply pressure without weeping. The internal components resist fatigue from repeated pressure cycles in irrigation or utility supply lines. Standard compliance ensures reliable operation over extended service intervals.

Thermal and hydraulic limits

The device handles fluid temperatures up to 180 degrees Fahrenheit without degradation of the brass body or rubber seal. Pressure drop across the valve remains minimal during normal flow, preserving downstream fixture performance. No external power or control signal is required for operation.

Questions about this item

Does the 125 psi rating hold up when the breaker runs continuously on a garden-hose line?

The Watts 8BC is rated for 125 psi maximum pressure, so it handles continuous garden-hose supply without exceeding its limit.

What thread type must the existing tap have for this breaker to connect?

It uses a 3/4 inch GHT connection, matching standard garden-hose threads on most outdoor taps.

Will the ANSI A 112.1.3 and ASSE 1011 markings satisfy local code when I keep my older brass hose bibb?

The breaker carries ANSI A 112.1.3 (ASSE 1011), ASSE 1001, cCSAus B 64.2, IAPMO and UPC listings, so it meets common code requirements alongside legacy fixtures.
