9. Water Supply & Plumbing P-trap: a typical plumbing trap that prevents sewer gases from escaping into the living space

10. Waste/Vent Piping Copper Water Piping (joints) Why not PVC? Pipe Insulation WC Rough-in

11. PVC Waste & Supply Piping for kitchen or bath sink

12. Plumbing Chase Vent Pipe Why “Stack” Plumbing Fixtures? Easier and less expensive if the plumbing is “stacked” vertically; back to back kitchen and bath with 2 nd floor bathroom over head. Framing accommodates area for rough-in plumbing to be ran and vented through to roof.

15. Nail Protector

16. This is a built-in clothes washer connection box. It provides an opening into the drain system for the drain hose and a valve controlled set of connections for its hot and cold supply hoses. The typical trap in the white plastic waste line is seen here along with the copper hot and cold supply lines.

18. Wastewater & Sewage Disposal Septic System A typical domestic septic system. Raw sewage flows by gravity from the house into a septic tank. After decomposition in the septic tank, a small amount of solid material falls as sludge to the bottom of the tank, and liquid effluent flows to the drain field where it leaches into the soil.

24. Electrical Rough-in

26. Electrical rough-in using flexible metal conduits

27. The rough boxes for a ceiling fan and for two recessed ceiling lights have been installed. These boxes may be adjusted left or right on their metal strap hangers and tilted so that the lamps project light directly down. They are also designed to keep cool enough to be safely covered with ceiling insulation. A standard rough recessed light box is secured to the ceiling joists with a steel strap and has been wired.

32. Furnace is in the basement (or attic) and blows warm and cool air through supply ducts to registers in the floor near the exterior wall of each room. The air returns to the furnace through a centrally located air duct with a return grill near the ceiling.

33. Insulated “Flex” Duct

34. Duct Anchorage Flexible Duct Insulation Sprinkler Pipe required in 3-story residential construction

37. Exhaust ventilation is required for areas of high humidity such as baths and kitchens. The flexible duct directs air from an exhaust fan over a tub out through a vent in the end wall of the house. The exterior vent is equipped with a flexible damper to avoid back-flow from outside in. The black plastic pipe through the roof is the vent for the plumbing drainage system.
