How is water supply pressure typically tested in plumbing?

• A. Using a faucet
• B. Using a pressure gauge
• C. By visual inspection
• D. By measuring water flow rate

Answer: (B)

Testing water supply pressure is commonly done using a pressure gauge, which provides a precise measurement of the water pressure in the plumbing system. A pressure gauge is attached to an outlet, such as a hose bib or a dedicated test port, where it can accurately capture and display the water pressure in pounds per square inch (PSI). This method allows plumbers to identify whether the pressure is within the acceptable range, which is crucial for the proper functioning of plumbing systems and fixtures. Faucets can give a general sense of water operation but do not provide an accurate measurement of pressure. Visual inspections can help in assessing other aspects of the plumbing system, such as leaks or damaged components, but they are not reliable for measuring water pressure. Measuring water flow rate is important for understanding system performance but does not directly indicate the pressure levels present within the lines, hence not suitable for pressure testing.
