For the last couple of months, one of our toilets gets small bubbles in the standing water. It looks like carbonated water in that the bubbles attach to the side of the toilet.

This toilet also clogs more easily than the other 3 that we have in the house. This toilet is one of 2 that we have on the first floor.

Any ideas as to what could cause this condition? I do not see water leaking anywhere underneath.

Do you see the bubbles as the tank is filling or do they just happen? Any larger bubbles? Can you give me amy more details? Regards, Tom

Thank you for responding...

No bubbles are seen while flushing and there are no large bubbles.

The bubbles are gone after the toilet is flushed, but then appear later after a couple of hours. I am not sure exactly sure about the time frame though.

I also notice them today in the other downstairs toilet??
