  1. I have a waterway chlorinator which was installed with the pool in 2002. I have a part which is leaking. Looking at the cutaway diagram, it looks like part # 8, but mine has a rubber connector on it, and the rubber split, causing water to shoot out. Whar is this part called and can I get a replacement for it?

    • Hi Larry,

      If the Chlorinator is from 2002, I would just replace the whole thing. Chances are once you replace that part another will fail. 7 + years is a good lifetime for a Chlorinator.

      Hope this helps,


  2. I have a Waterway Chlorinator that was installed two years ago. Recently, the water flow to it has stopped considerably. The water level in it will slowly drop until the chlorinator is dry. Any ideas on how to fix this??


    • Hi Elizabeth,

      Maybe try cleaning it out. Could there be a small piece of Chlorine maybe blocking one of the port holes? I have seen that before.

      Hope this helps.

    • If there are no cracks in the chlorinator, I would replace the part only. I have seen chlorinators last for 20+ years.
