    Vacuum Breakers

    Also known as vacuum-breaking valves, these valves have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping.

    Elbows are designed for intermittent flow. They discharge liquid directly and should not be installed in areas where spillage could cause damage.

    Prevent dirty, contaminated water from backing up into your garden hose line—install these vacuum breakers between a faucet and a garden hose. Also known as vacuum-breaking valves, these valves have a built-in check valve that blocks backflow, so you can leave your hose in a utility sink full of dirty water without the water going back into the line.
    When the check valve is closed, it has vents that open to release the water. This reduces pressure in the line and confirms the valve is working. Because these valves vent water, use them in environments where spilled water won’t cause a problem. This design adheres to ASSE Standard 1011 for valves with a vent.
    Mount valves to faucet outlets with a set screw, and easily thread or unthread a hose while the valves stay in place.
    Valves comply with Uniform Plumbing Code (UPC) and are CSA certified, so they're safe to use in sanitary plumbing systems because they prevent contamination from flowing backward into your line.
    These valves are designed to be used intermittently. They've been tested under ASME A112.1.3, which assumes the valves will not be used for more than 12 hours at a time.
    Tamper-Resistant Set Screw—Valves with tamper-resistant set screws have a head that breaks off after tightening to prevent valve removal after installation.
    NSF/ANSI 372—Valves that meet NSF/ANSI Standard 372 are certified lead free.
    Chrome-Plated Brass Body—Chrome-plated brass valves are more corrosion resistant than plain brass valves.

    Heavy Duty Check Valves with Push-to-Connect Fittings for Drinking Water

    A metal body provides more durability than plastic. Insert tubing into the push-to-connect fittings—no heat, solder, or flux required. These valves meet NSF/ANSI 61 for use in drinking water systems. They open to allow flow in one direction and close when flow stops or reverses.

    Flow Coefficient (Cv)—Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
