Storm ASBU07Y Brass Anti-siphon Body with Union 3/4 in

Product Description

The STORM ASBU07Y is a 3/4-inch brass anti-siphon body with union, designed to prevent backflow and protect potable water supplies from contamination caused by backsiphonage. This fitting is installed on irrigation systems, hose bibbs, and outdoor water supply lines where a physical backflow barrier is required by local plumbing codes. The union connection simplifies removal and reinstallation during service, making it a practical choice for plumbers and irrigation technicians working on residential and light commercial systems. The all-brass construction provides corrosion resistance and long service life in wet or buried installations.

This anti-siphon body is suited for outdoor potable water supply applications including lawn irrigation controls, hose stations, and similar systems that require code-compliant backflow protection at the point of use. The 3/4-inch size is the most common diameter in residential irrigation mainlines and hose-side connections. Licensed plumbers and irrigation contractors typically install this fitting when connecting irrigation valves or outdoor supply lines to a domestic water system where direct cross-connection with soil or standing water is possible.

Key Features

• Brass construction for corrosion resistance in wet and buried service environments

Compatibility

Designed as an OEM-style replacement or new-installation component for 3/4-inch brass anti-siphon valve assemblies on residential and light commercial irrigation and outdoor water supply systems.

Installation Notes

Installation is performed by a licensed plumber or certified irrigation technician. Shut off the main water supply and depressurize the line before disassembling any fittings. Apply thread sealant tape to all threaded connections and torque fittings by hand-tight plus wrench turns per standard practice — do not overtighten brass threads. Verify local plumbing authority having jurisdiction (AHJ) requirements for backflow prevention device approval before installation.
