Key Features to Consider When Shopping
Selecting the right backflow preventer involves evaluating size, valve type, installation flexibility, and specific application needs. Common considerations include:
- Valve Types: Double check valves for moderate hazard protection, dual check for low-hazard residential use, and reduced pressure zone (RPZ) assemblies for high-hazard scenarios like chemical mixing.
- Materials: Lead-free alloys ensure compliance with modern health codes and long-term reliability.
- Connection Styles: NPT threads, union fittings, and quarter-turn shutoffs for quick service.
- Design Innovations: Freeze sensors, modular components, compact footprints, and versatile mounting options (vertical or horizontal).
- Size Range: From 1/2" for homes to 3/4" for higher flow demands.
These features make WATTS products versatile for irrigation, fire protection, and process water systems. Buyers often prioritize ease of testing and repair, where WATTS excels with top-entry access and replaceable parts.
