This 3/4 inch hose connection vacuum breaker is designed to prevent backflow and protect potable water supplies from contamination caused by backsiphonage. It allows for the safe attachment of portable hoses to hose thread faucets while ensuring polluted water cannot reverse flow into clean water lines.
Constructed with a durable brass body and chrome finish, this unit features stainless steel internal components, a rubber diaphragm and disc, a draining stem, and a break-away set screw for tamper-resistant installation.
Ideal for both indoor and outdoor use, this vacuum breaker is suitable for health hazard applications requiring non-continuous pressure, including service sinks, swimming pools, photo developing tanks, laundry tubs, wash racks, dairy barns, marinas, and general gardening applications.
Please consult local inspection authorities for installation requirements. Maximum working pressure is 125 psi (8.6 bar).
