A bottle trap, which can be unscrewed for cleaning. Because it is a localized low-point in the plumbing, sink traps also tend to capture small and heavy objects (such as ...
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.

Sanitary sewer installation with PVC pipe. Sanitary sewers are sized to carry the amount of sewage generated by the collection area. These sewers are much smaller than combined sewers, which are designed to also carry surface runoff.
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.
Grease trap sizing is based on the size of the 2- or 3-compartment sink, dishwasher, pot sinks, and mop sinks. Many manufacturers and vendors offer online sizing tools to make these calculations easy. The cumulative flow rates of these devices, as well as overall grease retention capacity (in pounds or kilograms) are considered.
