Leak in the supply line to the bathroom
We just moved into our first home. The house is 11 years old. The house is on two levels. There is no crawl space. On the ground level there is a half bathroom (i.e. toilet). I have noticed that the floor of the bathroom gets slightly wet from time to time. I cannot see any leaks or drips from the toilet bowl or any pipes. We kept a dry paper towel on the floor in the night. The next morning the paper towel is wet. I don't know from where the water is oozing onto the floor. Is it possible that the water supply line is below the floor (or behind the side wall near the floor level) and a leak there is causing the water to ooze onto the floor? How will a professional investigate the cause of the leak? Will they have to rip open the floor or side wall? I am scared. It is just one month since we moved into what we thought was a picture perfect home, and we are already starting to see problems. Please help.
