Plumbing Symbols

Plumbing symbols are used on technical drawings to represent the location of certain fixtures, such as plumbing faucets, valves, pipes, etc.

It is necessary to identify these plumbing items, on house and building plans, in order to ensure that all tradesman involved on a project are clear on where water pipes, drainage pipes, shut off valves, and other plumbing objects will be installed.

A plumbing drawing is also very useful to contractors when performing plumbing estimating to determine construction costs.

Often times, contractors from different trades will discuss engineering and architect's plans in a meeting to decide if there may be conflicts between architectural, structural, electrical and mechanical (including plumbing) trades.

After reviewing contractor concerns, and depending on which stage of construction the project is at, the designer may decide to relocate certain plumbing related icons on the drawings to let the builders know that an amendment has been made.
