A backflow preventer can be installed in residential and commercial areas to prevent a cross-contamination between water sources. For example, those who have city water at their home must have a backflow preventer installed after the meter to protect the city’s water supply. Each backflow preventer is required to be tested annually to confirm the valve is working properly.
