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.

90° Elbow

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

Vacuum Breakers with Garden-Hose Fittings

Set Screw

Tamper-Resistant

Set Screw

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.

High-Pressure Vacuum Breakers

Rated for 12 times the pressure of standard vacuum-breaking valves, these can handle up to 1,500 psi. Also known as vacuum-breaking valves, they have vents that open when pressure drops to relieve vacuum conditions and prevent backward suction from drawing liquid into upstream piping. Body is 316 stainless steel for excellent corrosion resistance.

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.

Air Admittance Valves

No need to vent your plumbing to the outdoors—these valves allow air into your drain, waste, and vent system. When wastewater drains, it creates negative pressure, which opens these valves. When water isn’t draining, they close to prevent sewer gas from escaping. To install, cement the plastic body to your vent pipe. They come as two pieces that thread together. Unthread the pieces to access your vent pipe or for cleaning.
