Storm 850DIAS100 Brass Anti-siphon Drip Valve 1 Inch

Product Description

The STORM 850DIAS100 is a 1-inch brass anti-siphon drip valve designed to prevent backflow and siphoning in irrigation and drip distribution systems. Built from brass construction, this valve provides reliable shutoff and backflow protection at the point of connection, keeping downstream drip lines and emitters free from contamination caused by reverse flow. It is typically installed by licensed plumbers or irrigation technicians working on residential or light commercial drip irrigation setups where backflow prevention at the valve level is required by local code.

This valve is suited for drip irrigation systems where low-volume, pressure-regulated water delivery is required. The anti-siphon design integrates backflow prevention directly into the valve body, eliminating the need for a separate backflow preventer at each zone. Typical installations include garden drip systems, landscape irrigation headers, and similar low-flow water distribution applications. A 1-inch connection size accommodates standard mainline sizing common in residential irrigation layouts.

Key Features

• 1-inch valve size fits standard mainline irrigation connections
• Brass body construction provides corrosion resistance and durability
• Integrated anti-siphon design prevents backflow without a separate device
• Drip-compatible for low-volume, low-pressure irrigation systems
• Order increment of 1 allows single-unit purchasing

Compatibility

Designed as an OEM-style replacement or new-installation valve for 1-inch drip irrigation and anti-siphon valve applications in residential and light commercial systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified irrigation technician in accordance with applicable local plumbing codes. Shut off the water supply and depressurize the line before removing or installing the valve. The anti-siphon valve must be installed at the correct elevation above downstream emitters as required by code to ensure proper backflow prevention. Do not install below grade or in a configuration that could submerge the anti-siphon port.
