SUB’s Residential Backflow Testing Program

Backflow assemblies keep contaminants, such as fertilizers and animal waste, from entering your home’s drinking water supply, and they must be tested each year during the lawn watering season. SUB has a new voluntary program to help make this process fast and easy. By signing up for our Residential Backflow Testing Program, SUB’s Water Service Center will arrange to have a certified contractor test your assembly.
