The valve will distribute the sanitary water from the main supply pipes to the water lines beneath your foundation, ensuring that hygienic and pure water reaches your home.DK Hardware offers a wide variety of backflow preventers to provide a safe and secure potable water supply. The Watts Rebuilding Kit prevents the reverse flow of polluted water from entering the potable water supply due to back-siphonage. It consists of a disk, disc float, a bonnet, and an O-ring. It is ideal for low flow, non-continuous hot or cold water health hazard installations such as laboratory equipment. It is most commonly used in commercial and industrial applications.
