ABSTRACT:
A cleaning device is proposed for hot water tanks which each include near a bottom end thereof a drain pipe for allowing water contained in the tank to be flushed out therefrom. The present cleaning device comprises a first conduit adapted to be permanently secured to the drain pipe of the tank, a second conduit, such as a garden hose, connected to a sewer or a drain, and a valve mounted between the first and second conduits for controlling the flow therethrough and thus the flushing of the water and of the impurities and residues contained in the tank. The valve is preferably of the motorized type and is actuated by a programmable timer in order that the tank can be automatically and periodically flushed without intervention from the user.
