Hot water tank cleaning device
First Claim
1. A device for cleaning hot water tanks of a type each including a drain outlet at a bottom end thereof in flow communication with water contained in the tank and also including a cold water inlet and a hot water outlet, the cold water inlet continuously supplying pressurized water to the tank, said device comprising a conduit means having first and second ends, a valve means on said conduit means intermediate said first and second ends thereof, said first end of said conduit means being connected to the drain outlet of the tank, whereby, when said valve means is opened, at least some of the water and impurities contained in the tank are flushed out of the tank through the drain outlet thereof at least partly under a pressure of the supply water continuously fed to the tank by way of the cold water inlet, said at least some water and impurities exiting the tank through the drain outlet then passing through said conduit means and said valve means and out of said second end of said conduit means for appropriate disposal thereof.

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.
