In Line Chlorinator Issues

Hi sunofthebeach! Welcome back for another season. I have always thought your username was very clever.

I see the same thing with my Hayward CL-200 inline chlorinator. When you take the lid off the water drains out. With the lid on the chamber is filled with air with no place to go. That is, no bleed mechanism. The thing will fill with enough water to work as the pressure in the pipes at the chlorinator will compress the air bubble some and let it work.
