The backflow preventer can be used in all plumbing systems where there is danger of the potable water supply system being contaminated. It prevents an accidental reduction in the pressure in the distribution system from causing backflow from contaminated water in user installations. The 574 comes complete with discharge air gap, all test ports are on top for easy access in spite of how the valve is mounted, union body connections make service and repair simple and fast, and a simple short list of parts is all that is required to do a rebuild.
