ABSTRACT:
An apparatus for cleaning a residential water heater 10 or the like without the need for draining and re-filling the tank. The water heater is generally vertically disposed and has a cylindrical side wall 12, a top 14, and a bottom 16. A water supply tube 20 terminates in a nozzle 22 which permits entry of a stream of water 24 in a generally horizontal spray pattern along the bottom to flush and agitate any foreign matter 38 along the bottom. A drain cock 28 is provided within the heater side wall and opposite the nozzle, the drain cock being opened upon flushing of the bottom of the water heater so that any foreign matter is removed through the drain cock. In lieu of a simple, single-orificed nozzle, a multiple-orifices nozzle 22b or a plurality of nozzles may be provided.
