A P trap is a U-shaped section of pipe used in plumbing that is intended to catch liquid or gas to stop unwanted flow, most notably preventing sewage gases from entering buildings while allowing waste products to pass through. Traps are employed in oil refineries to stop hydrocarbons, other harmful gases, and chemical smells from escaping down drains.
The similar function is employed in heating systems to prevent thermo-siphoning, which would let heat escape to places where it is not desired. To maintain a local gas while the system consumes liquid, some pressure gauges are connected to systems via U bends. They can be made to seem like full pipe loops for aesthetic purposes, forming many U’s for greater effectiveness.
The design of the trap causes it to hold some water after the fixture has been used. This water forms an airtight seal that stops sewage gas from leaking back into the building through the drain pipes. Practically every plumbing item, such as a sink, bathtub, or shower, must have either an internal or external trap. Internal traps are almost always present in toilets.
P traps also have a tendency to catch small and heavy objects (like jewelry or coins) that are unintentionally dumped down the sink since they are a localized low spot in the plumbing. In addition, traps frequently gather hair, sand, food scraps, and other debris and regulate the size of anything that can enter the plumbing system, trapping larger objects. Because of all of these factors, the majority of traps have a cleanout feature or can be dismantled for cleaning.
A vertical vented pipe known as a standpipe can be linked to a trap where a significant amount of water may be evacuated through it quickly in order to prevent the breaking of the seal in other neighboring traps. Standpipes are most frequently used in homes for clothes washing machines because they quickly dispense a lot of wastewater while draining the wash and rinse cycles.
