Backflow Prevention

Water distribution systems are designed with the intention of having water flow in one direction, from the distribution center to the many various points of use. Unfortunately, hydraulic conditions can and do exist that may deviate from normal conditions, causing water to flow in the opposite direction. This undesirable reversal of flow is called backflow and can draw outside contamination back into the main water lines.

This is a job for professionals. For your backflow preventer to pass the test, you must have a certified professional plumber conduct the test. If it doesn’t pass, it’s either time to repair it or replace it....

Our plumbers can take care of both the testing and repair or replacement of backflow preventers. We’ll make sure your business isn’t at risk, and that you won’t have to shut down because of a backflow prevention device violation.


Backflow prevention devices are essential for ensuring we all have healthy drinking water, but they can fail. All backflow prevention assemblies have calibrated internal components that break over time.

Common components such as the springs, seals, and various moving parts inside a backflow prevention assembly will eventually wear out or fatigue. Periodic testing is the only way to ensure that your backflow prevention device is in proper working order.



Backflow is simply the reversal of water flow to the source from which it came. If the water is contaminated when it returns to its source, it can pose a major public safety concern.


A backflow prevention assembly is a necessary mechanical assembly that prevents contaminated water from flowing out of common systems. Backflow prevention assemblies are installed, typically at the water meter, to protect the drinking water supply against any pollutants and containments from a cross-connection within the water system. A cross-connection can be any arrangement, either temporary or permanent whereby a public water supply is connected, directly or indirectly, to any other water supply system that may contain containments. Hazards common to cross-connections include an in-ground irrigation system, a garden hose, a secondary source of water such as reclaimed water or a well, a swimming pool, or a body of water such as a lake or pond. If there is a change in water pressure from the main supply system due to a line break or a loss in pressure, the direction of flow can change, causing the backflow of potentially unsafe drinking water into the public drinking water supply system.

Periodic testing is the only way to ensure that your backflow prevention device is in proper working order.
