ABSTRACT:
A unitary package for water treatment for attachment to a home hot water heater which is adapted to be easily serviced and readily monitored by the homeowner. The water treatment device is an electrical machine especially adapted for separating magnetic particles in feed water pipes to home hot water heaters and the like. The electrical parts for operating the machine comprise a transformer fitted with a safety fuse in the primary winding thereof which steps down incoming household line voltage from 110-125 volts AC to about 24.+-. 4 volts DC in the secondary winding. The secondary winding provides a constant DC voltage to an electromagnetic coil surrounding the inlet pipe. The inside of the inlet pipe is fitted with a special spiral band impeller or a solid helical impeller which rotates only when the water flows. The spiral band and the helical impeller are made of ferromagnetic material and are very close (about 1/16 inch) to the wall of the inlet pipe thereby sweeping in a broom fashion the inner wall free from particles which tend to deposit on the wall. The magnetic unit is a separate part of the package, separated from the transformer. A monitoring light is connected to the secondary winding to show that the circuit from the electromagnetic field is live. The package unit and pipe can be fitted by the homeowner into the water line.
