I have bubbles in my toilet tank. They are coming through the fill valve. I replace the fill valve and continued to have the problem with the new valve. The problem has been ongoing for several months. It doesn't seem to cause any other problem but the bubbles continue to come. I have no idea where the air comes from. Any answers would be appreciated.

Are you on a pump or city water?

I am on a well/pump however these bubbles are ongoing for about 6 months. So I doubt that I have a bladder leak
