MEASUREMAN 1" Pressure Vacuum Breaker PVB — 1" Bronze Backflow Preventer for Sprinkler & Irrigation, Centerline Test Cocks

MEASUREMAN's 1" Pressure Vacuum Breaker is a heavy-duty bronze backflow preventer built to stop backsiphonage and protect irrigation systems and potable water supplies.

This pressure vacuum breaker (PVB) by MEASUREMAN is a field-ready backflow device engineered for sprinkler and irrigation applications where reliable protection and long service life matter. Made from a precision-cast copper alloy, the assembly resists outdoor corrosion and simplifies seasonal maintenance with centerline test cocks for draining and inspection. It connects with standard 1-inch NPT female threads and is intended for use where backsiphonage prevention is required by local codes.

How does this device prevent contaminated water from entering my supply?

The PVB installs downstream of your water meter or controller and creates a one-way barrier that stops siphoning when downstream pressure drops. An internal check and atmospheric vent work together to break any potential vacuum and discharge back into the atmosphere rather than into the potable system.

• Internal check valve prevents reverse flow.
• Atmospheric vent opens to break vacuum conditions.
• Designed specifically to guard against backsiphonage scenarios.
• Meets typical irrigation backflow protection needs (verify local code requirements).

What materials and build features improve durability outdoors?

The body is precision-cast from a copper alloy that provides high strength and corrosion resistance suited to wet outdoor environments. Threaded connections, solid internal components, and accessible test cocks make the assembly robust and easy to service over years of seasonal cycles.

• Premium copper alloy body resists rust and degradation.
• Solid construction tolerates irrigation flow conditions and soil exposure.
• Weatherproof finish reduces maintenance frequency.
• Standard 1" NPT female threads for reliable, leak-minimizing connections.

How simple is installation, testing, and winterization?

MEASUREMAN placed test cocks at the centerline for straightforward access during installation, verification, and routine testing. Those same ports enable quick draining and winterization so you can reduce freeze damage risk without disassembling the valve.

• Centerline test cocks streamline mounting and regulatory testing.
• Integrated ports allow fast draining for cold-weather protection.
• Compatible with common 1" piping and fittings to speed install time.
• Requires only basic tools and typical plumbing sealants to install correctly.

Will this fit my sprinkler or drip irrigation system?

The assembly uses standard 1-inch NPT female threads, making it compatible with most residential and commercial irrigation lines that accept threaded fittings. Confirm pipe size and local backflow requirements before purchase to ensure compliance and correct placement within your system.

• Standard 1" NPT female threads match common irrigation hardware.
• Designed for sprinkler, drip, and zone-control piping setups.
• Check local code for required backflow device type and installation location.
• Professional installation recommended for code compliance and testing.

Who this is for: The MEASUREMAN 1" Pressure Vacuum Breaker is suited for homeowners, landscapers, and irrigation contractors who need a rugged, easy-to-service backflow solution for sprinklers, drip systems, or small commercial irrigation zones. If you want a corrosion-resistant, testable device that fits standard 1" pipe and simplifies winterizing and compliance testing, this PVB is a practical choice.
