This product is designed for use with top end power flushing pumps when cleaning large domestic or small commercial systems. The product has two powerful rare earth magnets, positioned in sequence so that moving debris is located for an extended time within a powerful magnetic field. This is said to snatch the maximum amount of debris from the circulating water, which runs clear much quicker. The company says that less water is needed to clean a heating system when using this product, and large amounts of corrosion debris are prevented from circulating through the waterways and heat exchange surfaces of boilers.
