<P> Since fire hydrants are one of the most accessible parts of a water distribution system , they are often used for attaching pressure gauges or loggers or monitor system water pressure . Automatic flushing devices are often attached to hydrants to maintain chlorination levels in areas of low usage . Hydrants are also used as an easy above - ground access point by leak detection devices to locate leaks from the sound they make . </P>
