Age old occurrence.

On another note, since it's a rainy, slow day for you, I have a
problem I'd like your input on.

Idiots built an entire subdivision and stuck ventilators in all the
bathrooms for show - but failed to vent them anywhere. After years of
use, the owners call with complaints of the sheetrock seams/tape
peeling off. Although it is obvious as to why, I'm not sure what the
best solution is. I've already found dead wall space and installed
metal pipes from the lower floors, and am now hooking up flexible pipe
to the upper floor bathrooms. The problem is the external vents. I
don't want to chop 4 holes in the roof, and getting at the eaves for 4
eave vents is problematic/impossible. (Too small w/ 6/12 pitch
W-Rafters on the inside, and 45 feet in the air on the outside.)

I'm considering running all of them together to one large roof vent,
but I'm concerned about blowback back into other bathrooms (yeah, they
do have some cheap-ass flapper), and the distance (condensation
dripping back) on some. As well, no one sells a 4 into 1 collector
for this purpose. Got any good ideas?

Thanks,

Greg G.
