Without it, everyday activities like watering your lawn or running your sprinkler system could put your drinking water at risk.

As long as your backflow device is accessible, the water is turned on and the test cap is in place, we should be able to test your device within 20-30 minutes. Learn more about how to prepare for your appointment.
