3 Introduction Industrial plumbing carries liquids and gases used to manufacture products Residential plumbing carries fresh water, gas, or liquid and solid waste Pipes are made of copper, steel, cast iron, or plastic

4 Pipe Types Plastic pipe Copper pipe
Glued and is commonly called PVC or CPVC For fresh water and waste Copper pipe Joints are soldered For hot or cold water

5 Pipe Types Steel pipe Cast iron
For large water distribution and natural gas Fittings are threaded Cast iron For solid and liquid waste as sewer pipe More quiet than plastic pipe

6 Sizing Pipe Requirements
Size of water supply based on: Amount of required water Supply pressure Pipe length Number of stories Flow pressure at farthest point from source

7 Energy Conservation Insulate hot water pipes
Run water pipes in insulated spaces and in the interior Locate water heater in heated space Select low-flow showerheads Caulk water pipes and drains at plates Seal all wall penetrations

8 Universal Plumbing Sinks Water Closet
Reachable from a wheelchair (about 34”) About 6” deep Use single-level or automatic faucets Water Closet Keep 42” of clear space beside the toilet Use elongated bowl about 15” to 19” high

9 Universal Plumbing Bathtub Showers Use single-lever controls
At least 60” long with a 15” seat Add a slip-resistant bottom and handles Showers Minimum length is 60” and width is 30”

10 Plumbing Schedules Specific information is given about the location, item, manufacturer and remarks for each fixture Each item must be carefully specified to avoid potentially costly errors Schedules should be located near plumbing plans

11 Plumbing Drawings Use a different sheet or layer for drawings
Fixtures can be place on floor plan drawing Draw plumbing lines thicker than wall lines Break lateral lines if they cross over others Sizes and specifications given as notes

12 Plumbing Drawings

13 Water Systems Water supply to the home is the main line and is 1” plastic pipe From main line to fixtures, 1/2” pipe is used Place plumbing fixture above each other Water heaters are placed on a platform and are gas, oil, solar flat-plate collectors or electric

14 Water Systems

15 Drainage and Venting Drainage system allows the solid and liquid waste to move to the sewer line Minimum slope of 1/4” per foot is required Vent system allows air to flow so gases dissipate and a vacuum is not created Use 3” or 4” pipe for drainage

16 Isometric Plumbing Drawings
Also called a plumbing riser diagram Shows a three-dimensional representation of the plumbing layout

17 Sewage Disposal Public sewers are located under a street
Septic systems contain a storage tank and absorption field for dispersion of liquids Percolation tests are used to determine if the soil is accommodating Sand filter systems are used if the soil is not appropriate for a leach field

18 Sewage Disposal

19 Commercial Plumbing Fittings and lines must be clearly shown
Symbols are used to indicate the pipe contents Pipe size is given with a leader or note Elevation of the pipe is given in feet and inches with an abbreviation Legends are given to show special symbols
