Drain, Waste, and Vent System Overview

Horizontales
A condition which may occur in the DWV system whereby a higher pressure than atmospheric pressure is created in the drain/vent piping, causing a reversal of the normal flow through drain piping and traps. Also referred to as backpressure backflow.
The drains from traps of fixtures to the junction of those drains with any other drain pipe
The level of the surface of water flowing in a partially-full pipe by gravity alone
Wastewater generated from domestic processes other than human-waste disposal. These include laundry, dishwashing and bathing.
When referring to plumbing, a ledge or lip in a fixture that controls the level of water inside the fixture
Traps with long downstream legs, which tend to promote siphonage. They are no longer permitted by code for new installations but are still found in older buildings
A situation in which one trap is attached to another, creating negative pressure that stops the intended flow of drainage
Loss of water in a trap seal started by unequal pressure inside and outside DWV piping. The water initially flows in the direction of the lower pressure.
The natural change from liquid to vapor of water at a temperature below it's boiling point
A general term for certain vertical DWV pipes, including offsets of soil, waste, vent or inside conductor piping.
Verticales
The part of the drainage system that extends from the end of the building drains and conveys its discharge to a public sewer, private sewer, individual sewer-disposal system, or other point of disposal
The tendency of water to be drawn into porous or fibrous material against gravity above the level of the water source
Devices designed and installed so as to separate and retain deleterious, hazardous or undesirable matter from normal sewage or liquid waste, while permitting normal sewage or liquid wastes to discharge into the drainage system by gravity
The amount of slope given to horizontal runs of pipe expressed as a height in inches per foot of run
Refers to the combined sanitary drainage and venting systems
An access point to the connected parts of the drainage system for the removal of blockages
Fittings that join pipes of different sizes or materials, such as copper and galvanized pipe or cast-iron and plastic pipe
A trap constructed in the shape of the letter "P" with the loop facing downward, which provides a water seal in a waste or soil pipe, used mostly in sinks and lavatories
