What are the different plumbing symbols used in a plumbing blueprint?

Pipes: Different line styles serve to represent various pipe types. Solid lines usually indicate main water supply lines, while dotted or dashed lines represent branch lines, vents, or drain lines.
Valves: Valves play a crucial role in controlling the flow of water within the plumbing system. Plumbing blueprints use various symbols to represent different types of valves. A gate valve, for instance, is typically depicted as a rectangle with a diagonal line drawn across it. A circle with an “X” inside of it symbolizes a ball valve, while a circle with a tiny cross or “T” inside of it represents a globe valve.

Fittings: Fittings are essential components in plumbing systems as they are responsible for connecting pipes and facilitating changes in direction or size. Plumbing blueprints utilize specific symbols to represent various fittings. An elbow fitting, for example, is depicted as a curved line, visually illustrating a change in direction. A straight line and a perpendicular line intersecting to form a recognizable “T” shape represent a tee fitting. Similarly, a cross fitting is represented by a straight line intersected by two perpendicular lines, forming a distinctive “plus” shape.
Fixtures: Plumbing fixtures, such as sinks, toilets, bathtubs, and showers, are represented by specific symbols. These symbols may vary depending on the blueprint’s standards or conventions, but often resemble simplified outlines of the fixtures.
Appliances: Appliances that connect to the plumbing system, such as water heaters or washing machines, have their own symbols. These symbols typically represent the shape and basic features of the appliance.
