What type of pressure does a pressure gauge specifically measure in plumbing?

A pressure gauge in plumbing is specifically designed to measure water pressure, which refers to the force exerted by water within a plumbing system. This measurement is crucial for ensuring that water is delivered at the appropriate force for various applications, such as fixtures and appliances, and helps in identifying potential issues like leaks or blockages in the system.

Understanding water pressure is important for plumbers when installing and maintaining systems, as it must meet certain standards to function effectively. By monitoring water pressure, plumbers can also assess the efficiency of the system and make adjustments as necessary to optimize performance or address any problems.

While other pressures, such as atmospheric, hydraulic, or gas pressure, might be relevant in certain contexts, they are not the primary focus of a standard pressure gauge used in plumbing settings. The gauge's design and calibration are specifically tailored to read the pressure of the water flowing through pipes, making it an essential tool for plumbing professionals.
