Most water closets, bidets, and many urinals have the trap integral with the fixture itself. The visible water surface in a toilet is the top of the trap's water seal. Each fixture drain, with exceptions, must be vented so that negative air pressure in the drain cannot siphon the trap dry, to prevent positive air pressure in the sewer from ...
In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains.
Generally, a toilet outlet has the shortest trap seal, making it most vulnerable to being emptied by induced siphonage. An additional risk of pressurizing a system ahead of a waste stream is the potential for it to overwhelm a downstream trap and force tainted water into its fixture. Serious hygiene and health consequences can result.

A bathtub, also known simply as a bath or tub, is a container for holding water in which a person or another animal may bathe. Most modern bathtubs are made of thermoformed acrylic, porcelain-enameled steel or cast iron, or fiberglass-reinforced polyester. A bathtub is placed in a bathroom, either as a stand-alone fixture or in conjunction with ...
Bacteria have been shown to live in "premises plumbing systems". The latter refers to the "pipes and fixtures within a building that transport water to taps after it is delivered by the utility". [43] Community water systems have been known for centuries to spread waterborne diseases like typhoid and cholera.
A trap primer (or trap seal primer) is a plumbing device or valve that adds water to traps.The water seals in traps are needed to prevent sewer gases from entering buildings, but because this water is exposed to the air, it is subject to evaporation over time in infrequently used floor drains, leading to the release of sewer gas into the environment.
Accessible bathtubs are bathtubs that can be used by people with limited mobility, disabilities, and the elderly. A bathtub can be made accessible for some people by the addition of grab bars or hand grips, or through the use of lifts that lower and raise the bather in the water. [1] Other bathtubs have been specially designed for accessibility.
