Backflow Prevention

The goal of backflow prevention is to stop contaminated water from returning to the clean water source. Backflow events or changes in water pressure can cause this to happen. 

Backflow is the reversal of a water flow that can introduce contaminated water from a non-potable source (sewer line, sprinkler system, etc.) back into the potable water supply.    

Backflow can contaminate the clean water supply with chemicals, bacteria, and other dangerous materials, which poses a serious risk to public health. In many places, backflow prevention devices are mandated by law to safeguard public health and safety. 

Reduced pressure zone (RPZ) assemblies, air gaps, and double-check valves are typical kinds of backflow prevention devices. 

Backflow prevention devices function by stopping the reintroduction of tainted water into the clean water source. An RPZ assembly, for instance, establishes a physical barrier separating any potential sources of contamination, like chemical tanks or sprinkler systems, from the potable water supply.  

Backflow prevention device installation and maintenance are frequently the responsibility of the property owner. To ensure that local regulations are followed, it is advised to seek advice from a backflow prevention specialist or licensed plumber.
