What Is a Double Check Backflow Device?
A double check backflow device, or double check valve assembly (DCVA), uses two spring-loaded check valves to help prevent reverse water flow. Water normally moves through the assembly in one direction. If backpressure or suction causes water to flow backward, the valves close to protect the clean water supply.
These devices are generally used for non-health hazards, including certain irrigation, commercial, and plumbing connections. They provide an added layer of protection where contaminated water does not pose a serious health risk. Systems that could expose drinking water to harmful contaminants might require stronger protection, such as a reduced pressure zone assembly.
Signs Your Double Check Device Needs Service
A backflow device can develop problems as it ages. Leaks, corrosion, internal wear, or failed testing affects how well the assembly protects your plumbing system. Helms Plumbing and Drains recommends professional plumbing inspection when you notice changes around the device. Watch for these warning signs:
- Water leaking around the assembly
- Lower-than-normal water pressure
- Rust or visible corrosion
- Buzzing, vibrating, or unusual sounds
- A failed backflow test
- Signs of damage around the device
- Water that appears cloudy or discolored
Double Check Device Repair, Replacement, and Installation
A failed double check assembly might need repair or replacement, depending on its condition. Our plumbers inspect for leaks, worn parts, damage, and other issues before recommending the right solution. Repair might restore a serviceable device, while severely damaged or outdated units would require replacement.
Helms Plumbing and Drains also provides backflow device installation.

Double Check Backflow Testing
Regular testing helps confirm that a double check backflow device is operating correctly. Testing is performed through the test ports on the assembly and should be completed with properly calibrated testing equipment. Many jurisdictions require periodic testing, so property owners should follow local rules for their specific system.
Helms Plumbing and Drains provides backflow device testing to identify problems with the assembly. Testing is usually needed after installation, repairs, replacement, plumbing changes, or when the device fails to perform properly. Our plumbers inspect the system and recommend the next step based on its condition.
Double Check Valve vs. Reduced Pressure Zone (RPZ)
Both devices help prevent contaminated water from flowing backward into a clean water supply. However, they provide different levels of protection and are designed for different plumbing risks.
Double check valve
Uses two check valves to stop reverse water flow. It is generally used for non-health hazards where backflow would not create a serious health risk.
Reduced Pressure Zone (RPZ)
Uses two check valves and a pressure relief valve. It provides stronger protection and is used when backflow could introduce harmful contaminants into the potable water supply.
