Preventing potable (drinkable) water from flowing the wrong direction.
Backflow prevention assemblies protect our drinking water from contamination, pollution and microorganisms.
Anywhere with water usable right from the tap has a cross contamination prevention program.
Backflow testing is a procedure performed by using a pressure differential gauge to assess the performance of the internal parts of your backflow prevention assembly.
Generally, the owner of the property where the backflow prevention assembly is located is responsible for arranging testing and payment. If you’re a renter you’ll need to consult your rental agreement, but most commonly it is the owner’s responsibility.
Manufacturers, and many municipalities, recommend annual testing. Any time an assembly is installed or repaired they must be tested. Your municipality will inform you by letter when your assemblies need to be tested. Fines or service interruption can happen if testing isn’t done by the due date.
The reason why backflow prevention assemblies are installed is to protect you and the community against possible cross contamination. Cross contamination can lead to illness or death from, microorganisms, pollutants or toxic substances.
In Michigan only plumbers with an ASSE 5110 certification are permitted to work on backflow preventers. Getting in contact with a company, like Residential Backflow Prevention, is how you can schedule a test for your assembly.
