An RPZ, or Reduced Pressure Zone assembly, offers the highest level of protection, suitable for high-hazard cross-connections. A DCVA, or Double Check Valve Assembly, provides moderate protection and is typically used for low to medium hazard situations, like irrigation systems. The choice depends on the application and local code rules.
A well-maintained backflow preventer can last 10 to 20 years or more. However, factors like water quality, exposure to weather, and the type of device can affect its lifespan. Instead of freeze protection, Hawaii homeowners are better served by watching for leaks, corrosion, and sun damage on exposed outdoor pipes and hoses. Regular testing and maintenance help extend its service life.
No. Testing must be performed by a certified backflow tester using calibrated equipment. Water providers only accept reports from licensed testers.
Backflow preventers stop contaminated water from flowing backward into the public supply during pressure drops. Irrigation, fire lines and commercial equipment are common sources of contamination. Water providers require them to protect public health.
Most municipalities and water utilities require backflow preventers to be tested annually. This confirms the device is working correctly to protect the public water supply from contamination. We can help you schedule these regular inspections.
