A system for preventing boiler low-water failures, caused by obstruction of the working components of low-water cutoff system, which includes a flushing unit attachment. The flushing unit attaches to the boiler low-water cutoff system in place of a manual blowdown unit. The boiler water make-up line is rerouted through the flushing unit, which is in fluid connection with the low-water cutoff system. When the low-water cutoff system detects a low-water level in the boiler it signals the water make-up line to add make-up water to the boiler. The make-up water is routed through the flushing unit, thereby creating a transverse flow of water in the flushing unit. The transverse flow created by the make-up water flushes rust, scale and other debris from the low-water cutoff system and out of the flushing unit. A discharge water line carries the rust, scale and other debris into the boiler. The manual blowdown unit may be reattached below the flushing unit to allow for periodic manual flushing of the low-water cutoff system.
