In plumbing, what does the term "static pressure" refer to?

The term "static pressure" specifically refers to the pressure in a water system when no water is flowing. This is an important concept in plumbing as it establishes the baseline pressure in pipelines when the system is at rest. Static pressure is a critical factor for determining how effectively water can be delivered throughout the plumbing system and is essential for ensuring that fixtures receive adequate water supply when they are in use.

Understanding static pressure helps plumbing professionals assess and design systems capable of delivering water efficiently without the risks of pressure drops or surges when demand varies. In systems where water is required to flow, it is important to know the static pressure as it can indicate potential problems such as leaks or necessary adjustments to maintain desired performance levels.
