9An excessive water pressure can be minimized using this valve
Pressure Reducing Valve
Supplies water to the plumbing fixtures by means of gravity
Overhead Feed System
A new concept in water distribution where compressed air is used as the delivery agent.
AIR PRESSURED WATER DISTRIBUTION
This type of water distribution is fast superseding
AIR PRESSURED WATER DISTRIBUTION
Used on tall building that could not be served adequately by the street main.
DIRECT UP-FEED PUMPING SYSTEM
It is a Triplex Pump installed to operate in sequence according to the volume of demand.
DIRECT UP-FEED PUMPING SYSTEM

JOCKEY
refers to the resistance produced by the following water with the fittings and interior surface of the pipe.
Friction
In water supply distribution, it is defined as the resistance between the molecules of water.
friction
The force required to move the water inside the pipe.
Pressure
water at rest
Static Pressure
Pressure available
Residual Pressure
the pressure range measured over a period of 24 hours
Normal Pressure
This valve will keep the pressure constant at 40 psi or can be reset to any other pressure desired.
Pressure Reducing Valve
The maximum water discharge of fixtures in terms of fixture unit.
Maximum Demand
One factor to be considered in determining the size of the water service pipe
Probable Demand
