A back flow device is used to prevent dangerous backflow in the water pipes caused by a sudden drop in water pressure. When such a drop occurs, water can reverse direction within the pipes, sending pollutants and contaminants back into the potable water supply.

To prevent this from happening, back flow devices like pressure valves and regulators are used, ensuring that the water will continue to flow towards your home or business.
