#8: Will my water service be interrupted? How long does a test take?

The ASSE standard testing procedures require that the water service be interrupted during the course of the testing process. These service interruptions are scheduled at the Owner’s convenience, and normally do not unduly disrupt business operations or domestic water usage. Test periods for devices 2" and smaller can usually be performed in under 10 minutes. Test periods for larger devices usually take from 5 to 15 minutes. Repair periods vary with the manufacturer of the device, but can usually be performed in a maximum of 20 minutes for small devices. Larger devices requiring repairs may take from one half hour to 1-1/2 hours.
