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.
