Storm ASVU07Y Brass Anti-siphon Valve with Union 3/4 in

Product Description

The STORM ASVU07Y is a 3/4-inch brass anti-siphon valve supplied as a complete assembly with a union connection. Anti-siphon valves prevent backflow by stopping contaminated water from reversing into a potable supply line when pressure drops. This valve is constructed in brass for corrosion resistance and long service life in water distribution applications. The included union fitting simplifies installation and future serviceability without cutting into the line. It is sized at 3/4 inch, a common diameter for residential and light commercial irrigation and plumbing branch lines. Licensed plumbers and irrigation technicians are the typical installers.

The ASVU07Y is suited for outdoor irrigation systems, hose bibb supply lines, and similar applications where backflow prevention is required at the point of use. The 3/4-inch port size handles standard residential flow demands. The brass body withstands outdoor temperature cycling and the mechanical demands of periodic valve cycling. Applications include residential lawn irrigation systems, garden supply lines, and commercial landscape irrigation tie-ins where a compact, union-equipped anti-siphon device is specified.

Installation Notes

Installation should be performed by a licensed plumber or certified irrigation technician in accordance with local plumbing codes and IPC backflow prevention requirements. Shut off the water supply and relieve line pressure before beginning work. Use thread sealant tape on all threaded connections and tighten unions to hand-tight plus firm wrench pressure without over-torquing the brass fittings. Verify proper orientation of the anti-siphon vent port — it must face upward to function correctly.
