77M_1The MainGuard #77M Washdown Hydrant provides the best in performance and value. Designed and engineered specifically for washdown applications, the #77M provides excellent high-stream flow rates using a water monitor for cleaning out retention basins, clarifiers, or other plant clean up applications. The unique inlet valve design allows for a full clear-channel flow (see illustrations) that is superior to other washdown hydrants for moving water and passing debris easily. The #77M is a freeze-less hydrant that drains to ground and can be used year round.
The MainGuard #77M comes standard with all brass principle working parts, variable nozzle sizes, traffic break-away, self draining non-freezing, and a 2” FIP vertical /straight inlet (optional side inlet available). The MainGuard #77M is fully serviceable from above ground.
