Water Pressure Ejector. This instrument, Fig. [550], is worked by water pressure and used to advantage in excavations, cellars, etc., where water pressure can be had and the required elevation does not exceed 12 feet. It has to be inserted into the water pressure pipe in such a manner that it will be entirely covered by the water to be raised. It will raise double the quantity of water which it obtains from the pressure pipe, i.e., it will deliver two gallons for every one it receives from the pressure pipe.
