'S' trap inlet to drain [further explanation needed]. The air lock phenomenon can be used in a number of useful ways. An 'S' trap (a pipe that descends from a reservoir, then curves back up, then down again) allows liquid to flow from top to bottom unhindered, and gas cannot flow through the trap unless it has enough extra pressure to overcome the liquid head of the trap.
The major categories of plumbing systems or subsystems are: [19] potable cold and hot tap water supply; plumbing drainage venting; sewage systems and septic systems with or without hot water heat recycling and graywater recovery and treatment systems; Rainwater, surface, and subsurface water drainage; fuel gas piping
In buildings with HVAC air handlers that admit outside air for ventilation, plumbing vents placed too closely to air intakes or windows can be a source of sewer gas odors. In some cases airflow around buildings and wind effects may contribute to sewer gas odor problems even with appropriately separated vents and air intakes.
In the United States, plumbing codes usually provide strict limitations on how far a trap may be located from the nearest vent stack. When a vent cannot be provided, an air admittance valve may be used instead. These devices avoid negative pressure in the drain pipe by venting room air into the drain pipe (behind the trap).

A Buchan trap (alternative names: Bristol interceptor, [1] interceptor trap and disconnecting trap) is a device fitted in a domestic sewer pipe to prevent odours entering the pipe from the public sewer [2] and permeating the house, a common problem before individual plumbing fittings were separately trapped.
