The method is for monitoring water quality in a water system. A pipe is provided for conveying water therein to a water system having a first particle sensor in operative engagement with the pipe. A second particle sensor of a monitor device is provided in operative engagement with the pipe upstream and outside the water system. The second particle sensor senses particles in the water of the pipe. The second particle sensor triggers a shut off of a valve, disposed downstream of the second particle sensor and upstream of the first particle sensor only when a sensed value of particles in the water reaches a predetermined level to prevent the water from entering the water system. The water in the pipe is diverted into a re-circulation line.
