This priming valve is for the AromaMist Aroma Bathing System pump.
The priming valve is located at the back end of the liquid end pump head. This valve bleeds the air out while priming the pump for aroma to initially move up from the aroma container into the pumps liquid end. It is only used when the pump is void of aroma and needs to be replenished.
One (1) priming valve is used per aroma pump.
