BEECO Backflow Preventer

Pressure drop activated trap seal primers are connected to the cold water supply line.   There is an internal cartridge that is activated when the line pressure changes by as little as 3 p.s.i. and discharges water from the bottom of the trap primer into a line that is connected to the p-trap or floor drain to maintain the water seal in the p-trap.  Otherwises, dry p-traps can lead to foul odors entering a building.
