The drain, waste, and vent (DWV) capacity is determined. The following components are inspected: Fixture traps, Vents, Drain lines, and House traps.
Tank water heaters consist of a glass-lined or vitreous enamel-coated steel tank covered by an insulated sheet metal jacket. They are gas-fired, or oil-fired, or electrically heated. The following components are examined: Plumbing components, and Fuel-burning components.
Tankless coil water heaters consist of small diameter pipes coiled inside of or in a separate casing adjacent to a hot water or steam boiler. They are designed for a specific rate of water flow, usually three to four gallons per minute. Since demand for domes-tic hot water can easily exceed this flow, such heaters often have an associated storage tank to satisfy periods of high demand. The following components are inspected: Plumbing components, and Controls.
The following components are inspected: Location and water quality, Depth and casing, Pumps, and Pressure tank and switch.
Except in cases where visible and accessible, the transportation line of a domestic waste system typically cannot be determined in the course of a non-invasive (without excavation) inspection.
