What is Backflow Testing?

Backflow Testing verifies that the device is effectively safeguarding your local drinking water. In this process, your plumber will close the downstream valve, pause for a short while, and then measure the system’s pressure using a dedicated backflow test kit. This procedure confirms that the pressure remains at the expected level and that the device operates correctly.
