Backflow is an undesirable reverse flow of a substance, can be water or otherwise, through a cross connection and into the drinking water system. These cross connections are found in residential homes and include the garden hose hook-up at the side of the house, irrigation system, and Hot Water Heating System to name a few. It is important to protect yourself and your family, by having a Certified Backflow Prevention Specialist install the Backflow Preventers in your home. Backflow Preventers have to be tested regularly, it is important to have a Certified Backflow Prevention Assembly Tester come in and test them yearly. Because they have many moving parts that can be subject to failure, it is crucial that you do not try and test them yourself.
