A system for periodically flushing accumulated sediment from hot water tanks including a drain valve controlled by an electric actuating means capable of rapid actuation of the valve from its normally closed position to a fully open position. The electric actuating means is electrically connected to a timing means, such as a time clock, for actuating periodic flush cycles. A flush cycle begins when the appropriate signal commands the actuating means to open the valve and ends upon closure of the valve. The invention contemplates that the duration of each flush cycle will depend on the water tank size, and that a series of flush cycles will provide optimized flushing of sediment from the tank.

[ What is claimed is:] [1.] A system for periodically and automatically flushing accumulated sediment from a liquid tank of the type having a drain existing thereon, said system comprising:a tank drain valve, said drain valve movable between a normally closed position and an open position;means for rapidly actuating said drain valve for moving said drain valve from said normally closed position to said open position for a predetermined period of time;timing means for controlling said means for actuating, said means for controlling causing said means for actuating to periodically open said drain valve for a predetermined period of time thereby flushing sediment laden liquid from within the tank through said drain valve;said timing means including a manual switch whereby a user may manually initiate and control actuation of said tank drain valve.
