104517 Trap Primer

A trap primer, also called a trap seal primer is a plumbing device designed to maintain the water seal in a plumbing trap. Plumbing traps rely on a small amount of standing water to block sewer gases from traveling back into a building. However, in floor drains or other fixtures that are rarely used, this water can evaporate over time, breaking the seal and allowing unpleasant and potentially harmful sewer gases to escape.

A trap primer prevents this problem by automatically adding water, either directly or indirectly into the trap. By periodically supplying small amounts of water, the trap primer ensures that the trap seal remains intact, even in drains that see little or no regular use.
