This downstream chemical injector is designed to add chemicals downstream from the pump.  In order to operate, a pressure drop must occur across the injector, which draws chemical into the water stream.  Once the pressure drop is established, the amount of chemical injection can be altered by means of an adjusting knob.

WARNING: This product might contain a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov
