I have purchased a Stenner pump and am about to start hooking it up, but not sure where to locate the injection point of the chlorine? Should it be before the pump where the pump is pulling the water? at the pump somewhere? or after the pump? If attached before the pump, there will be a bit of vacuum pulling the chlorine, if after the pump, Im guessing there will be a sort of pressure pushing the chlorine back into the injection tube?
Any thoughts would be greatly appreciated!
