What is the minimum pressure (in pounds per square inch) that a facility water supply must maintain?

The correct answer is: 20

The minimum pressure that a facility water supply must maintain is crucial for ensuring that water systems function effectively, particularly in settings where water is needed for fire suppression and sanitation. A pressure of 20 pounds per square inch (psi) is established as the minimum requirement. This level is sufficient to ensure that water can flow adequately through pipes and fixtures, while also allowing for necessary pressure relief to avoid potential damage to the system from excessive pressure. Maintaining this minimum pressure is essential for the operation of various water-dependent systems, especially in commercial or industrial settings where the demand for water can be significant. A supply pressure below this threshold may lead to insufficient flow rates, which can hamper emergency response efforts and overall facility management. This standard helps to ensure safety and reliability in water supply systems.
