APPLICATION, INSTALLATION AND OPERATING PRINCIPLE
The Smith Trap Seal Primer Valve, when properly installed in a cold water supply line running to a frequently used fixture and connected to a floor drain trap, will insure a constant seal of fresh water in the drain trap.
When water is drawn at the plumbing fixture the resulting flow activates the trap primer valve mechanism. A precise amount of water is dispensed into the trap at the beginning and end of flow in the fixture supply line.
Air ports in the primer body prevent siphonage of trap water into the water supply line. If the trap water seal is not constantly maintained, the water will evaporate from the trap, allowing sewer gas to escape into the building from the sewer lines.
