Backflow Preventer Inspection & Testing

Backflow testing and repair are crucial processes in maintaining the safety and quality of your water supply system. Backflow occurs when the normal water flow in a plumbing system is reversed, potentially allowing contaminated water to flow back into the clean water supply. This can happen due to changes in water pressure, like during a water main break. Backflow can introduce pollutants, chemicals, and other contaminants into the potable water supply, posing a serious health risk to you and your family.

Here’s an explanation of backflow testing and repair:

Backflow Testing

Backflow Testing

Backflow testing is conducted to ensure that prevention devices installed in a plumbing system are functioning properly and effectively, preventing the reverse flow of water.

Devices Tested

Various prevention devices are installed at different points in the plumbing system to safeguard against backflow. These include air gaps, check valves, and reduced pressure zone (RPZ) assemblies.

Testing Process

Our licensed backflow tester uses specialized equipment to measure the pressure and flow of water through the backflow prevention device. The device’s performance is compared against established standards to determine if it’s functioning correctly.


Backflow testing is typically required annually or as mandated by local regulations and guidelines. Testing frequency may vary based on the type of property (residential, commercial, industrial).

Backflow Repair

Failed Tests

If a backflow prevention device fails the testing process, repairs or replacements are necessary to restore its proper function.


The cause of the failure is identified, which could range from worn-out parts to damaged components.

Repair or Replacement

Depending on the severity of the issue, the backflow prevention device may need repairs, such as replacing worn seals or springs. In some cases, if the device is irreparably damaged, it might need to be replaced with a new one.

Certified Professionals

Licensed Testers

Backflow testing and repair should only be performed by licensed professionals who are trained and certified in backflow prevention techniques.

Authorized Repair

In case of failed tests, only authorized professionals should perform repairs or replacements to restore the device to its proper working condition.

Regulations and Compliance

Local Requirements

Backflow testing and repair requirements vary by jurisdiction. Many areas have regulations that mandate regular testing of backflow prevention devices, especially in commercial and industrial settings.


After testing is completed, results are documented and submitted to relevant authorities to demonstrate compliance.

Backflow testing and repair are essential to maintaining the safety and integrity of the water supply. By ensuring that backflow prevention devices are functioning correctly, communities can prevent the contamination of their drinking water and protect public health.
