DAY 4: AFTERNOON Dr. JOHN BRYANT

EQUIVA CONSTRUCTIONCAMP COSC PLUMBING Objectives »Materials »Code Considerations »Plumbing potable water supply Drain/Waste/Vent »Drawing Interpretation plan riser diagrams

EQUIVA CONSTRUCTIONCAMP COSC General Potable - drinking water Hard - high calcium carbonate content, prefer < 200 ppm »softening improves sudsing - zeolite treatment Flow Rate - gpm Head Pressure - column of water 1 foot high »0.434 psi/ft (62.5/144) Mains Pressure - typ psi »pressure regulator, backflow preventer Fixture Pressure - pressure required to operate a plumbing fixture Fixture Unit (FU); Drainage Fixture Unit (DFU) »weighted flow demand for a plumbing fixture for supply (FU) and waste (DFU)

EQUIVA CONSTRUCTIONCAMP COSC Codes IPC and UPC - Which one? »International Plumbing Code is Endorsed by; Building Officials and Code Administrators International (BOCA) International Conference of Building Code Officials (ICBO) Southern Building Code Conference International (SBCCI)

EQUIVA CONSTRUCTIONCAMP COSC Codes UPC and IPC - Which one? »Uniform Plumbing and Uniform Mechanical Codes are Endorsed by; International Association of Plumbing and Mechanical Officials (IAMPO) ICBO Key Point is to Make Sure You Know Which One is in Effect for Your Project!

EQUIVA CONSTRUCTIONCAMP COSC Materials and Methods Plumbing Design is Concerned with Piping Connections to Equipment »Water Service Pipes - copper, plastic, galvanized iron »Water Distribution Pipe - copper, plastic, galvanized »Above Ground Drainage and Vent Pipe - cast iron, type K, L, M, or DWV copper, galvanized, plastic »Underground Building Drainage Pipe - plastic, cast iron »Building Sewer Pipe - asbestos cement, cast iron, concrete, plastic, vitrified clay »Building Storm Sewer Pipe - asbestos cement, cast iron, concrete, type K, L, M, or DWV copper, vitrified clay

EQUIVA CONSTRUCTIONCAMP COSC Piping HVAC and Plumbing Systems Have Common Types »Steel Galvanized and Black (gas) - fittings and welded »Copper - usually soldered fittings Type K, L, M »Plastic PVC (polyvinyl chloride) PB (polybutylene, grey) FRP (fiberglass-reinforced plastic) CPVC (chlorinated PVC) PE (polyethylene)

EQUIVA CONSTRUCTIONCAMP COSC Corrosion Protection Use Di-Electric fittings to avoid Galvanic Corrosion, (especially on brass/iron connections) Plastics are the only Pipe Materials that are simultaneously light, flexible, tough, and corrosion resistant

EQUIVA CONSTRUCTIONCAMP COSC Hardware Valves »Gate; shutoff / isolation »Ball; regulate flow »Check; allows flow in one direction only »Pressure Reducing »Hose Bib; valve with hose connection Fittings & Accessories »Elbows, Tees, Flanges, Couplings, Unions »Air Management; air entrained in water can lead to “locks” in system »Hammer Arrestor »Trap Primer

EQUIVA CONSTRUCTIONCAMP COSC Fixtures Water Closet (WC) »vitreous china w/integral trap »wall and floor mount models »flush valve (commercial, ready for immediate reuse) Water Cooler/Drinking Fountain »individual fountain w/self contained water cooling units Sinks »lavatory, service, kitchen Urinal »similar to WC, siphon-jet, blowout, washdown, wall mount

EQUIVA CONSTRUCTIONCAMP COSC Drain, Waste, Vent - DWV General Items »Floor Drain Vent Within 12 ft. of Drain »No Drain Should Empty into a Smaller Drain »Vent at Least 1/2 Diameter of Drain to Which it is Connected »Not > 25% of Vent Length can be Horizontal »Good to Use 4” VTR »VTR Must Extend at Least 6” Above Roof, 12” is Better

EQUIVA CONSTRUCTIONCAMP COSC DWV General Items »Don’t Locate VTR Near Air Intake »Air Gaps at All Water Supply/Waste Outlets »4” Pipe Good Practice for W.C. »Connection Between Building and Floor Drain not Permitted by Some Codes »Building Drain Must be 4” if WC is on System

EQUIVA CONSTRUCTIONCAMP COSC Fixture Components Trap »Prevent backflow of sewer gas into the building space Air Gap »vertical separation between water supply and fixture rim

EQUIVA CONSTRUCTIONCAMP COSC DWV Trap Seal/Primer - prevents trap from drying out Clean Out (C.O.) - provides access to drainage stacks and main horizontal branches for cleaning Materials »Cast Iron, copper, clay, plastic, RCP

EQUIVA CONSTRUCTIONCAMP COSC Site Work Check Those Inverts! Where is Tie-in? Utility Coordination

EQUIVA CONSTRUCTIONCAMP COSC Storm Drainage Exterior Areas Require Drainage for Rain/Snow »roofs, patios, parking areas, roadways, landscaping, etc. Sizing of system depends on Rate rather than Total Size must be coordinated with public drain capability Codes dictate 1hr duration and 100 year event

EQUIVA CONSTRUCTIONCAMP COSC Rough-in What Are These? Is Slope Adequate?

EQUIVA CONSTRUCTIONCAMP COSC Rough-in Why do Dimensions Matter? Where are Fixtures to be Located? Does Everything Match? Is Now the Time to Ask?

EQUIVA CONSTRUCTIONCAMP COSC Rough-in Do Dimensions Matter? Layout Lines?

EQUIVA CONSTRUCTIONCAMP COSC Rough-in Do Dimensions Matter? Note Seal on PVC Waste Stack What Fixtures are Going in Here?

EQUIVA CONSTRUCTIONCAMP COSC Rough-in Backfill and Compacting. How Much? Soil in Pipe? Was it Inspected and Tested?

EQUIVA CONSTRUCTIONCAMP COSC Rough-in Floor Sinks in Right Location? Protection? Is Anything Missing? Is Now the Time To Ask?

EQUIVA CONSTRUCTIONCAMP COSC Rough-in Why Should Dimensions Matter? Why Sleeve Copper Penetrations Through Concrete? What Fixture is Being Connected Here?

EQUIVA CONSTRUCTIONCAMP COSC Rough-in Was it Tested? Did it Pass? What Goes in Here? Is Anything Missing? Is Now the Time to Ask?

EQUIVA CONSTRUCTIONCAMP COSC Rough-in What Are These? Traps Connected to Primer?
