ABSTRACT:
Sediment can be removed from hot water heaters via the method and apparatus of the invention. The tank is drained and the drain tube is used for access to the bottom of the tank. Water jet probes connected via a hose to a water supply are inserted through the drain valve opening, and are directed in such a way that the sediment is forced into suspension and runs out of the tank through the drain tube, around the probe. Preferably, the water and sediment drain into a pan, and preferably a pump is provided to pump water from the pan to a drain or other remote discharge location.
