I am having problems with the Chlorination not sending chlorine to the house. My unidose pump is working find its about 16 years old but I have been servicing it yearly with new parts and the water softener is working find. I can see the chlorine coming through the tube from the pump but I am only getting one cut off/in pump at a time from the pumptrol pressure switch. Is this the way the pump should be working? Or do I need to replace it? I need fast help because I am getting a lots of iron in the water in the house.

Thanks, Gadgetman64
