I have a single-story ranch house with a leak in bathroom, above tub. Hoping someone can help.
Toilet and bathtub are on same side of bathroom (tub only, no shower) separated by floor-ceiling wall. A cast-iron soil stack comes straight down from the roof above the center of the tub and makes first 90 degree turn parallel to tub toward floor-ceiling wall.
The leak is at a second fitting, when pipe makes a second 90 degree turn down floor-ceiling wall.
With the snow, I haven't been able to check roof from the outside. Opened ceiling/went up into the attic and noticed the following:
Went to DIY shop and asked for advice. They mentioned it was likely a loose pipe and to tap back into place . Have done that and leak seems to have stopped, but just not comfortable closing hole back up, without knowing why the leak happened or if that was the actual fix.
- Checked pipe every day for 4 days, always wet at fitting.
- Leak is only 1-2 drops at a time. Bathroom ceiling damage is old and about 2í diameter. (Just bought home so donít know how long itís been leaking).
- Outside of pipe is dry, except at fitting.
- From inside of the attic, roof is ok, no water damage.
- Followed vent pipe to basement; no visible signs of water traveling that far
Attached photo is at location of leak (now-dry), looking up from the tub.
-What is causing the leak?
-What else should I check?
-What should I do to fix?
