Fig. 14. — Pneumatic tank supply system with tank in basement supplied by hand force pump. 



Each tank is equipped with a pressure gauge w^hich will show the 

 internal pressure at any time. If water is pumped into the tank 

 until the pressure gauge registers 25 pounds, water can be forced 

 about 60 feet above the tank. If a discharge cock 20 feet above the 

 tank is opened, water is discharged until the pressure falls to 8.6
