Tap pressure primarily works due to the height of water storage tanks relative to the point of use, creating pressure through gravity. The higher the tank, the greater the pressure.
Here's a breakdown:
-
Water Storage: Water is typically stored in elevated tanks or reservoirs, often located on hills or towers.
-
Gravity's Role: The height difference between the water level in the tank and the tap creates a pressure head. The weight of the water column above forces water down into the distribution system. This is similar to how the water pressure increases the deeper you go underwater.
-
Distribution System: The pressurized water flows from the tank through a network of water mains and pipes that deliver water to homes and businesses in the community.
-
Pressure Variation: Water pressure can vary throughout the day depending on water usage. High demand periods (e.g., mornings and evenings) can lead to lower pressure, especially in areas further from the water source or at higher elevations.
-
Pumps: In some systems, especially those serving large areas or areas with significant elevation changes, pumps are used to maintain adequate water pressure. These pumps supplement the pressure provided by gravity.
-
Pressure Regulators: Pressure regulators may be installed in homes or businesses to reduce water pressure from the main line if it is too high. This helps prevent damage to pipes and fixtures.
In essence, tap pressure is a direct result of gravity acting on the water stored at a higher elevation than your tap, forcing it through the pipes to your home.
