Abstract
A device and method for chemicals to be fed into a water system, treating the water system as it enters, for example, a fire protection mains and/or fire protection systems (FPS) to protect and maintain the longevity of the water system preventing damages to the water system or enhancing the operation characteristics of the system. This device is a treatment system that may be installed as a portable or permanent device with chemicals such as, corrosion inhibitors, wetting agents, polymeric dispersants, biocides, biostats or other water chemical enhancing effects with means for injecting the chemicals into the fire protection system or a bypass feed system utilizing the fluid means without the need for any electricity. Activation of the pump occurs when water enters the FPS mains and FPS sprinkler system from an outside source. Valving is included to isolate the pump and drums, storage tank to prevent backflow from the FPS.
