Do Pressure Reducing Valves Prevent Backflow at Jason Davies blog

Do Pressure Reducing Valves Prevent Backflow. First, no, they don't function as a check valve. Yes, a pressure reducing valve can malfunction and cause backflow. These points are check valves that open and close, allowing upflow travel and stopping reverse travel. To prevent backflow, as well as back siphonage, a backflow preventer incorporates a series of check points that respond to pressure. This pressure regulation is vital to the proper functioning of backflow preventers by ensuring public and private water lines remain separated. Pressure reducing valves help to regulate these fluctuating mains pressures, keeping them down to an appropriate level during times when they might otherwise. They limit inflow by dynamically changing the valve opening so that when less pressure is on the out side, the valve opens up fully, and too. This can happen if the valve is not properly maintained or if it becomes damaged. Regulator valves are installed in conjunction with backflow equipment to maintain consistent water pressure levels throughout the piping. This relief valve opens the regulator (and the water in it) to the introduction of pollutants, and so it must be downstream of the backflow preventer to safeguard the potable water.
