If testing with a gauge between 10 psi to 100 psi, what increment must it have?

In the context of pressure testing for plumbing systems, having the appropriate increments on the gauge is crucial for accuracy and effective diagnostics. When the range of the gauge is between 10 psi and 100 psi, the ideal increment is 1 psi. This level of granularity allows for precise monitoring of small pressure changes, which is particularly important in plumbing systems where even slight deviations can indicate potential leaks or other issues.

Pressure testing often requires accurate readings to ensure compliance with safety standards and to identify any problems with the plumbing installation. A gauge that measures in 1 psi increments affords the technician the ability to detect small fluctuations that could otherwise go unnoticed if the increments were larger. This precision is vital when troubleshooting or verifying the integrity of a system.

Increments that are too large, such as 2 psi or 5 psi, may overlook significant issues that only a 1 psi measurement would reveal. Therefore, a gauge with 1 psi increments is the most effective choice for testing within the specified range.
