When Are Abbreviations Used in Plumbing?

Plumbing abbreviations are used to effectively communicate certain terminology without unnecessary wording. Common places you’ll see these abbreviations are:

  • Blueprints
  • Work orders
  • Supply procurement

Examples of Plumbing Abbreviations in Use

For example, let’s say a blueprint needs to show two kinds of pipes to connect. To do so, a male pipe and female pipe would be used.

The male iron pipe, or MIP, would be noted alongside a female iron pipe, or FIP.
