My pool size is about 30K to 32K gallon. I use a pentair 320 inline chlorinator (it is definitely not a new one but I don't know the age of it.) The chlorine level has been always low and my local pool professional told me it has flaw design, which makes it not working properly. I searched online and people saying the high-flo feeder kit #R171099 may help. I installed one last week. But the chlorine level is still low. There are something that I cannot explain besides the low chlorine, hope you can help me out. (The control valve has always been at full open notch.)
1. before I install the hi-flo feeder kit, whenever I open the top cap, I can see the high water level dropping. But after I installed it, the water level not dropping any more.
2. with the cap open, I can definitely see the water feeding into the cylinder. But I don't think it can tell anything, because I have the cap open when I view it.
3. the way I connect the hi-flo feeder kit is from right-after pump to the top hole of the feeder.
I wonder if there is anything that I need to clean or replace so it will work.
thank you very much.
