The WATTS 792036 is a 1/4-inch vacuum breaker finished in chrome, designed to prevent backflow and siphonage in plumbing and fluid-handling systems. Vacuum breakers protect the potable water supply by allowing air to enter the line when negative pressure occurs, stopping contaminated water from being drawn back into the supply. The chrome finish provides corrosion resistance and a clean appearance suited to both exposed and semi-exposed installations. This fitting is installed by licensed plumbers and pipefitters in residential and light commercial applications.
The 792036 is suited for use on faucets, hose connections, irrigation risers, and similar 1/4-inch threaded ports where backflow protection is required by plumbing code. It is appropriate for low-pressure water supply lines where a compact, atmospheric-style vacuum breaker meets the protection requirement. Its small footprint makes it practical in tight spaces or on equipment with limited clearance around the connection point.
Designed as an OEM-style replacement or new-installation vacuum breaker for 1/4-inch threaded plumbing connections requiring atmospheric backflow protection.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements for backflow prevention devices. Shut off the water supply and relieve line pressure before removing any existing fitting or installing this vacuum breaker. Apply thread sealant tape appropriate for potable water systems to the male threads before making up the connection. Do not install this device in a position that would submerge the air inlet port, as this will defeat its backflow protection function.
