Abstract

PURPOSE: To arrange such that a pressure water is fed to an upper story for which a head from an elevated tank is not satisfactory, and water in the elevated tank is fed effectively to a lower story by providing the elevated tank and the pressure water tank in parallel.
CONSTITUTION: When a feed water apparatus 26 for stories B, C... other than the uppermost story A is opened, water kept in an elevated tank 12 is circulated by way of a feed water pipe 21; when water falls below given low water level L.W.L., a long electrode 20 of a level detector 17 is detached from the surface of water to an operation of a controlling circuit 18, and an automatic valve 14 is opened to allow the water to flow in the tank. When the quantity of water comes up to a given high water level H.W.L., a short electrode 19 comes in contact with the water to an operation of the controlling circuit 18, and the automatic valve 14 is closed. Next, when the feed water apparatus 26 for the uppermost story A is opened, water is fed through a pressure water pipe 22 from a pressure water tank 13, and a lift pump automatically operates immediately against the fall of water in the tank.
