3/4 in Brass Vacuum Breaker

The CASH ACME 17148 vacuum breaker installs on 3/4 inch FNPT connections to prevent back-siphonage in potable water lines. Its brass body and Buna nitrile seal meet ASSE 1011 and CSA B64.2 standards for cross-connection control. The unit suits residential and commercial plumbing systems requiring atmospheric venting.

125 psi pressure rating and 180 °F limit

Rated for a maximum pressure of 125 psi, the breaker handles typical municipal supply pressures with adequate headroom. The temperature range of 0 to 180 degrees Fahrenheit covers standard hot water distribution. Systems exceeding either limit will require a different protection device.

Replaces worn atmospheric vent valves

This breaker replaces failed or code-noncompliant vacuum breakers on hose bibbs, irrigation taps or utility sinks. The upgrade is worth it when inspection demands ASSE 1011 compliance or when the original valve leaks under back-pressure. It does not serve continuous-pressure applications or high-hazard containment needs.

Questions about this item

Will the 3/4 in FNPT brass vacuum breaker thread onto my existing GHT hose bibb?

The unit has a 3/4 in FNPT inlet and a GHT outlet, so it screws directly onto a standard garden-hose thread bibb without an adapter.

How can I confirm the breaker is venting correctly once installed?

Open the supply; water should flow freely. Shut off the downstream valve — the internal check should close and the vent port must release any back-siphonage, showing the ASSE 1011 device is functioning.

Does the 17148 package include a replacement Buna-N seal or mounting hardware?

The breaker ships assembled with its Buna-N seal installed; no extra seals, washers or mounting brackets are supplied in the box.
