PNEUMATIC WATER SUPPLY SYSTEM.

PNEUMATIC WATER SUPPLY SYSTEM.

Grea_____uccess has attended the use of the pneumatic water supply system and apparatus at Kewanee, Ill. Not unfrequently the plumber, particularly in suburban districts, where there is no water supply under pressure, is called upon to install a plumbing system with all of the modern fixtures and conveniences that are enjoyed in the largest cities where a water supply system under pressure is available. Where the water must be pumped from wells, the use of large tanks on the top of buildings is not always possible, owing to the fact that old buildings are not sufficiently strong to support the weight, and, when the tank is supported by a special tower, there is some danger of freezing the service pipes. It is claimed that all this is avoided where the pneumatic system is adopted. In it the pneumatic tank may either be buried underground or placed in the cellar, where there is no danger of freezing. The water can be pumped into this tank either by hand or by power, then an air-pressure sufficient to drive the water to the highest fixtures and delivered under considerable pressure is supplied by means of the force-pump and the pressure is then maintained and regulated by means of an automatic valve. Where a large quantity of water is desired, larger tanks may be provided and windmills or other forms of power utilised for pumping the water into the pneumatic tank. Where the air-pressure is supplied by means of a force-pump, it is possible to carry such a pressure as will make the water available for flooding the highest parts of the building in case of fire, or for sprinkling lawns covering a considerable area, by means of a hose.
