Leak from bathroom sink bowl
I had an inspector come in my condo and he said the bathroom sink bowl was leaking after running water for 5 minutes. I had a master plumber look at the sink and could not find any leaks even after filling the bowl many times and even letting it overflow into the overflow area. This is the only sink in the house that has the outside facuet attached to it. The temperature here is 90 and where the condo has been empty, the air conditioing is not on. I also lived in this condo for 10 years and never had that sink leak. My question is-could this be condensation from the pipes and sink being warm and then running water for 5 minutes will cause condensation? There is no cracks in the bowl and this is the only sink "leaking" and the only one with an outside wall. Thanks for your help!
