What does "F.H." denote on plumbing plans?

The designation "F.H." on plumbing plans stands for Floor Height. This term is crucial in construction and plumbing documentation as it indicates the height of the finished floor in relation to other structural elements, allowing plumbers and other trades to properly plan the installation of plumbing fixtures and systems. Understanding this measurement is vital for ensuring that pipes and other components are correctly positioned and meet code requirements.

In plumbing plans, accurate floor height dimensions ensure that all fixtures, such as sinks and toilets, are installed at the appropriate height for usability, accessibility, and drainage. It helps coordinating between various systems in a project, ensuring that everything fits together seamlessly.

While other terms like Fresh Water Height, Final Height, and Foundation Height could be relevant in different contexts, they do not accurately describe what "F.H." specifically refers to in plumbing layouts.
