We just had new ceramic flooring installed the guy replaced the toilet gaskets. We just not downstairs right below where the upstaires toilet would be that we have a water leaking from the bulkhead. The paint is bubbled . Could the installer have done something to cause this.

Check for any water around the toilet. If there is none, change your wax ring under the toilet. If this doesn't fix your problem, then you will need to cut into the ceiling from below and find exactly were the water is coming from. This shouldn't be to big of a deal since you are going to have to tear out this portion of the ceiling anyway to repair any water damage.

I would call the installer to come back and fix it, good luck.

The installer has to come back and reset the toilet ! It is not set right. He has to either add a wax ring or set the toilet straight over the hole...

Good advice from all. Any call back and repair to the water damage should be absorbed by the plumber. You shouldn't have to be charged for anything. Good luck, Tom
