Yesterday, as my wife was so kind to let me sleep in for once, I was awoken anyhow by a couple of gallons of water coming through my first floor ceiling into my family room.
My two smallest were play with a few toys made for water in about 4 - 5 inches of water in the bathtub above. They are nothing more than a few little race cars that change color when put in cold water.
When they were done playing, my wife went up there and drained the tub. Within a half hour she noticed water dripping from the ceiling directly below the bath tub that soon migrated across the entire ceiling.
Here is the kicker, after turning off all the water and draining the lines, I pulled a small section of the ceiling out to get a look up in the ceiling where the damage started. About 2 gallons of water came out. After drying out a bit I could not find any burst pipes or damage anywhere. My first instinct was that this might be from a frozen pipe, because this plumbing is only a foot from an outside wall and the temps here in the northeast lately have been in the teens at night.
Next, I decided to try and turn the water supply back on slowly to see if I could pinpoint a leak. NOTHING LEAKED. Therefore, I tried filling the tub and draining slowly. Still NOTHING. I had a contractor come over and he could not find a leak either. The drains have been clear and are still clear. His only guess as to how all of this water may of ended up coming through the ceiling is that there could have been enough of a clog above the P-trap where the tub drain comes into the line that might have caused an uplift in the draining and it perhaps came down around a bad seal at the drain stopper level.
Any and all ideas/suggestions would be greatly appreciated.
