Hi guys- first time here. Wow, looking over this forum, I would say salt is here to stay!

I'm still in the stone age. Hayward CL200- anybody ever get a lemon? I put in a new one last year and the valve dial stuck toward the low side, wouldn't go all the way off. Chlorine levels were crazy. I worked with the valve dial this year and got it freed up to where it moves like it should, full range. But it seems to be stuck wide open. How could they (or I) mess up such a simple device?
