Frequently Asked Questions

Q. "What is the purpose of a trap primer?"
A. Traps dry up (water evaporates) when they aren't used, causing sewer odors to enter the area served by that trap. Floor drains are the most common traps that aren't used on a regular basis.

Trap primers are devices that connect to a cold water line. It is installed in-line. Every time that cold water is used on that cold line, a small amount of water trickles down to the trap that is connected to the trap primer. The small trickle will keep the water seal from drying up.
