Product Q&A
Q:How to choose the right backflow preventer?
A:
For potable water, RPZ backflow preventers are best for high-risk areas. Consider size, pressure, and hazard level. Double check valves suit lower risk, while RPZ offers top protection.
Q:Why are backflow preventers crucial in water systems?
A:
Backflow preventers are vital for protecting drinking water from contamination due to back pressure or siphonage. Required by most codes and in high-rise buildings, they safeguard public health and prevent cross-connection hazards.
Q:Can backflow preventers be used in fire protection systems?
A:
Yes. Specialized backflow preventers in fire protection systems stop non-potable water from re-entering the municipal supply, ensuring safety while meeting fire and water standards.
Q:How do backflow preventers enhance safety in HVAC and industrial water systems?
A:
Backflow preventers protect chilled, heating, and process water systems from reverse flow contamination, maintaining water quality, preventing equipment corrosion, and ensuring regulatory compliance in commercial and industrial settings.
Q:What are the available nominal pressures?
A:
The valve is available in PN10 (1.0 MPa) and PN16 (1.6 MPa) pressure ratings.
