Found a leak in a water pipe from our upstairs bathroom.
Leaking down to ceiling below.
Just a relatively small leak, but did damage the ceiling below a little.
The defective pipe that was repaired was about waist high in the upstairs
Small section cut out to repair and re-solder, but impossible to see below
to the the joists
etc. on the bathroom floor.
Have a fan blowing on it thru the cutout repair hole for a few days to dry
out hopefully any dampness.
Was wondering though:
a. how many days should I keep the fan going ?
b. Is there some powder, or something, to blow into the hole which
hopefully would get down to the joists to help prevent any mold, etc. from
forming before buttoning the cutout up ? Or best to just let "air-dry" ?
I am worried that I can ever truly dry out fully the wood joists and ceiling
plaster that got damp, so am a bit concerned; or, will it dry out in time
with the fan going for a week or so ?
