When considering the impact of altitude valves, what is the outcome when pressure in the distribution system drops?

When the pressure in the distribution system drops, altitude valves are designed to respond by opening to allow flow. This mechanism is crucial for maintaining system pressure and preventing issues associated with low pressure, such as air infiltration or pump cavitation.

Altitude valves function based on the principle of sensing the water level in a tank or reservoir. If the water level drops due to water being used or a decrease in supply pressure, the altitude valve will open to allow more water into the system to restore the appropriate pressure and level. This is essential for ensuring a continuous and adequate supply of water to the consumers served by the system.

In instances where pressure decreases, the opening of the altitude valve helps to balance the system and maintain operational efficiency, making it an essential component in a water distribution system.
