Frequently Asked Questions

A backflow preventer is a device used to protect potable water systems from contamination by preventing water from flowing back into the system. It ensures that water flows only in one direction, safeguarding the quality of drinking water.

We offer a variety of backflow preventers, including double check valves, reduced pressure zone (RPZ) devices, and pressure vacuum breakers, suitable for both residential and commercial applications.

The right backflow preventer depends on your system's needs, including the type of water supply, pressure requirements, and local codes. Refer to product specifications or contact our customer service team for guidance.

If your system uses water, such as in hydronic heating or cooling, a backflow preventer may be required by local codes to protect against contamination. It’s best to check with a professional or local regulations.

Installation typically involves placing the backflow preventer in the water line to prevent reverse flow. It’s important to follow the manufacturer’s instructions or hire a licensed plumber to ensure proper installation and compliance with local codes.
