A double check valve is an important part of your home or building’s plumbing infrastructure. It’s function is to prevent backflow and ensure the correct direction of water flow within the plumbing pipes. This helps protect water supplies from contamination.
Common Uses for a Double Check Valve
The double check valve is ideal for preventing back siphonage and pressure. In high hazard applications a different check valve or reduced pressure zone device may be necessary. Most commonly, double check valves are used for lawn irrigation systems, fire sprinkler systems and boiler systems.
Installing a Double Check Valve
A double check valve is installed as a complete unit. Within the assembly there are two shut off valves, two check valves and four test cocks.
Unless you have plumbing experience, the installation of a double check valve is often best left to professional plumbers. These units come with specific directions for installation, maintenance and repair. Often, it is wise to get the system tested by a certified backflow assembly inspector. It is important to test for leaks after installation.
In addition, sometimes it may be best to replace a double check valve assembly with a new pressure vacuum breaker.
An experienced plumber can help ensure your back up valves and systems are properly installed and maintained as part of your overall plumbing system.
