摘要

Scale reducing apparatus for water pipes comprises a helical insert in a feed pipe which terminates in a nozzle. This is connected to a pump and some of the water passes through a connector to bypass pipes which feed it back to the suction side. The nozzle or connector is fitted with permanent magnets which treat the recirculating water.
