how long should water stay in a wall?
I've just opened up a few walls to remodel a bathroom. The area under the window that is right behind a toilet is wet. The drywall is moldy and black and the insulation was wet. it's been open for a few days now and the moisture is about gone. I bought the house in July and was told the toilet leaked so I turned the supply off and just now got to the demo. I can't see where there is a current leak and the supply has been off for several months. Is it reasonable for the moisture to remain for that long? Thanks, 1

How do you know it's not the window that leaking?
Post some pictures.

It's possible but, the window is well tucked under an eve and the moisture is extended by several inches into the next wall at the corner heading to the insides of the house. I'll try to post pics but I'm not very good with that sort of thing.

There is usually a large vent pipe in the wall behind the toilet---it may be possible that the vent pipe is leaking or the roof cap is no longer keeping out the water---

Pictures will help---that should have dried out long ago---picture of the inside and the outside wall and roof,if possible---Mike---

you could also turn the supply back ON & flush the toilet a few times,,, that may eliminate or confirm 1 source of the leak,,, to complete the ' test ', sit upon the throne/can while flushing,,, sometimes body weight causes stress not found during flushes w/'no-load' ( so to speak ) :whistling2:
