Backflow happens for several reasons, and it can be a health hazard when it comes to drinking and bathing water. Backflow can cause drinking water to collect contaminants, creating a significant hazard for the people in the structure. Backflow preventers are small plumbing fixtures designed to protect against backflow. A properly installed backflow preventer keeps water running in the appropriate direction to keep contaminated water away from drinking water supplies. Call United for your backflow preventer installation, testing, and repair to ensure your water lines are always running the right way.
