Pumps located above the source of water supply must be capable of 'drawing' the water to them when they are started empty, or if incapable of so doing, both the pumps and the suction lines must be filled with water previous to starting; that is, they must. Be primed. This is accomplished by the use of a. Hand pitcher-pump or equivalent power-driven unit, connected to the highest point of the pump case, by means of which the air is withdrawn from the pump and suction pipe. The discharge valve being closed during this Operation, the water rises from below and replaces the air as the latter is withdrawn.
Or, the priming may be accomplished by filling the pump and suction pipe with water from some available supply, a flap valve being located at the bottom of the suction pipe to prevent the loss of the priming water. When the first method is used, the discharge valve is opened automatically or by hand as soon as the pump is started. If the second is used, the flap valve, or foot valve, opens automatically as soon as the pressure of water above is relieved. Pumps whose operat ing parts are submerged in the source of supply require no priming.
