All drainage pipes must be connected to vents. A waste stack carries the other waste from a sink, washing machine, or dishwasher. This seal prevents gases from the sewage system entering the building.įrom the trap sewage travels through drainage pipes in branch lines to a vertical stack. The trap catches and holds a small quantity of water to provide a seal. Some traps are part of the design of the fixture and are not visible, as in a toilet or double sink. A trap is the u-shaped pipe found below a sink. The first component connected to a fixture is a trap. Plumbing drawings are usually numbered beginning with "P," as in P-1, P-2, etc. A plumbing floor plan will typically show the location and type of plumbing fixtures, as well as the route pipes will be run (overhead or through walls) for potable water, drainage, waste, and vents. Drainage works by gravity: Drain pipes must slope downward. Water is supplied under pressure through pipes to plumbing fixtures. Plumbing systems involve two major components, water supply and drainage. The ability to save a design will be added in the future versions.Plumbing drawings provide all pertinent information on the design of the plumbing system for a project, including line sizes and location, fixture location, isolation valves, storage-tank capacities, hot- water-heater capacities and locations, and drain locations and routing. To take a printout - Take a print screen snapshot, then paste it to an image editor and use that image for sharing, printing or email purposes. Change grid to visible/invisible (use invisible grid to take screenshot) Touch and tap the pipe to move it behind all the pipes ( useful feature when pipes overlap)ħ. Create elbows and T-joints and rotate them to the corresponding angleĤ. Please see the video to see the app in action.Ģ. Purpose - The purpose of this app is to help in drawing quick pipe sketches, communicate ideas on the field, or review designs with your supervisor before making a detailed design in a CAD software. Isometric paper tool This app helps in drawing quick isometric pipe sketches along with elbows, T-joints and Valves.
