A backflow preventer is an essential device that works to keep your home’s water flowing in one direction. Without it, your water may become contaminated and unsafe. Because of the seriousness in nature of a failing backflow preventer, it is important to have the device inspected annually. Backflow preventers may break down because of an accumulation of debris, damage, or the age of the unit. It only takes an hour or less to do the testing and it is worth it in the long run. When it comes time to schedule your yearly test, call us. We serve Los Banos, Turlock, Patterson and Merced and we can help!
