Backflow testing ensures the device is working to protect the drinking water in your area. During a backflow test, your plumber will turn off the downstream shut-off valve, wait a few minutes and test the pressure in the system using a special backflow testing kit. The test is carried out to ensure the pressure is as it should be and the device is functioning.

Properties with a high or medium hazard rating must have a backflow device test carried out after the device installation and then once a year after that.
