Backflow is the flow through a cross-connection from a potential source of contamination back into the drinking water system.
There are two main causes of backflow: backsiphonage and backpressure.
Any unprotected or inadequately protected cross-connection on your premises could contaminate the potable water supply for your customers, employees and even neighboring homes and businesses. Severe illnesses have resulted from cross-connection contamination events that could have been easily prevented.
You are responsible for all unprotected or inadequately protected cross-connections on your premises and liable for any damages or illnesses they may cause. In cases where business owners have been proven at fault for cross-connection contamination events, judges and juries have awarded plaintiffs substantial monetary damages.
Each cross-connection must be eliminated or properly protected by an approved backflow preventer. All work done on the internal plumbing system of your facility must be performed by a state-licensed plumber. Any changes to your plumbing must be approved by your local plumbing inspector.
