RPZ backflow devices protect potable water connections where backflow presents a potential health hazard. They are commonly used in settings where contaminated water or other substances could enter the drinking water supply, including:
Commercial plumbing systems
Protect water connections in businesses, offices, and other commercial properties.
Irrigation systems
Prevent contaminated irrigation water from flowing into the potable water supply.
Industrial systems
Protect connections exposed to chemicals, process water, or other contaminants.
Fire protection systems
Provide backflow protection for certain fire suppression water connections.
High-risk plumbing connections
Help protect drinking water where the connection presents a higher contamination risk.
How Does It Protect Your Water Supply
RPZ devices provide a higher level of backflow protection than double-check valve devices. Their design creates a physical barrier against contaminated water entering the potable water system.
This device uses two check valves with a reduced-pressure zone between them. When pressure changes create a backflow condition, the relief valve releases water from this zone. This action helps prevent contaminated water from moving backward into the potable water supply.
Schedule Regular Backflow Device Testing
Regular backflow device testing checks the device's check valves and relief valve to verify that they operate within the required pressure ranges. Testing also identifies problems that need repair or replacement. Testing requirements vary based on local regulations and the type of connection. Our plumbers test the device, check its components, and identify problems that need repair or replacement. Schedule RPZ testing:
- After installing a new RPZ assembly
- Following repair or replacement work
- During required annual testing
- After changes to the property's plumbing system
- When the device fails to perform as expected
- When the relief valve discharges continuously
Watch for Signs of Device Problems
RPZ devices have several internal components that need regular testing and inspection. Problems with the check valves or other parts need prompt attention to prevent further damage or device failure. Watch for these signs of RPZ problems:
Water discharge
Continuous water discharge from the relief valve signals a pressure or component issue.
Reduced water pressure
A noticeable drop in water pressure suggests a blockage or internal problem.
Leaks around the device
Water around the device signals worn seals, loose connections, or damaged parts.
Rust or corrosion
Rust or visible corrosion shows wear on the device or its connections.
Unusual sounds
Hissing, buzzing, or vibrating sounds suggest pressure changes or worn internal parts.

Severe damage, repeated test failures, or an outdated device requires replacement. We remove the old device and install a new RPZ unit that fits your plumbing system and meets applicable requirements. After installation, we test the device to verify proper operation.
