Backflow Enclosures and Freeze Protection in Union City, NJ
Above-ground assemblies sit in direct sun in summer and can freeze on cold nights. Winter freezes are a regular event in New Jersey, and pipes in exterior walls, crawlspaces and unheated garages are the usual trouble spots. We install insulated enclosures, freeze blankets or heated cabinets based on your location. Enclosures also discourage theft, since brass backflow assemblies are a common target for scrap thieves. We choose enclosures with enough room for testing and repairs.

The double check valve assembly, or DCVA, is a widely used backflow preventer for low-hazard applications where the consequences of backflow are not severe.

Our certified plumbers carefully install these devices, making sure both check valves operate correctly and are properly sealed to prevent backpressure or back-siphonage into the main water supply.

Frequently Asked Questions About Backflow Preventer Installation in Union City
Residential pressure vacuum breakers usually cost $250 to $700 installed. Double check and RPZ assemblies for larger homes or businesses range from $800 to $3,500 or more depending on size and enclosure needs.
You likely need a backflow preventer if you have an irrigation system, a fire sprinkler system, a swimming pool or any auxiliary water source that connects to the main water supply. Local regulations in Union City often mandate these devices for certain applications to protect public health.
Backflow is when water flows the wrong way through a pipe and carries contaminants into the clean water supply. It can happen from back siphonage during a pressure drop or back pressure from pumps and boilers.
Backflow preventers are installed at cross-connection points where non-potable water could enter the potable water supply. Common locations include irrigation system connections, fire sprinkler lines, boiler systems and connections to auxiliary water supplies, often just after the main water meter or at the point of hazard.
Most residential installs take two to four hours including testing. Large commercial assemblies can take a full day, particularly if piping must be reconfigured.
Many jurisdictions require a permit for new backflow assemblies, especially on commercial properties. We check local rules and pull the permit when needed.
Most municipalities require annual testing of backflow preventers by a licensed, certified backflow tester. This verifies the device is working correctly and continues to protect your potable water supply from contamination. We can also assist with scheduling these annual tests.
Constant dripping or discharge from an RPZ relief valve, low pressure downstream and a failed annual test are common signs. Visible corrosion or a cracked body from freezing also means service is needed.
