What is commonly used to detect water pressure issues in plumbing systems?

A pressure gauge is a crucial tool for identifying water pressure issues in plumbing systems. It accurately measures the water pressure in pipes and fixtures, providing vital information on whether the system is operating within the manufacturer’s specifications. By displaying the pressure in psi (pounds per square inch) or bar, the gauge allows plumbers to assess if the pressure is too low, which could indicate a leak or obstruction, or too high, which might lead to potential damage to the plumbing system and fixtures. Understanding the pressure levels helps ensure the effective and safe operation of the plumbing system.

In contrast, while a flow meter measures the flow rate of water through the system, it does not provide direct readings of pressure. Similarly, a thermometer measures temperature and a water level indicator provides information about water levels, neither of which is useful for assessing pressure specifically. Thus, the pressure gauge is the most appropriate instrument for detecting water pressure issues in plumbing systems.
