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.
A trap primer automatically injects water into a trap, maintaining a water seal to keep sewer gas out of buildings. It must be installed in an easily accessible place for adjustment, replacement, and repair. A trap primer, a specialized valve, is usually connected to a clean-water supply in addition to a DWV system. [21]

Crapper improved the S-bend trap in 1880. The new U-bend plumbing trap was a significant improvement on the "S" as it could not jam, and unlike the S-bend, it did not have a tendency to dry out and did not need an overflow. [7] The BBC nominated the S-bend as one of the 50 Things That (have) Made the Modern Economy. [8]
