you want to avoid hitting a sewer line.

Yea but most of that is confided within the concrete isnt it ? I always
thought the sewage lines from the house to the septic go out through the
side embedded within the concrete ... ? � Or do the lines actually go
underneath the slab as well ?

if i were you i would just spend the bucks and have the pros install
the system for 800 bucks. around here its generally a few thousand.

Like I said , theres many complications with that. �If I were to install it
outdoors , the fan would have to be outside...and temps get to -10
faurunheit in the winter here. � Fan wouldnt last long. � Plus this is an
unusual installation. �The only estimates I ever got were for doing the

Not sure if anyone would even work with my current situation.

sewer lines nearly all underground, slab most likely 4 inches, sewer
pipe 4 inch diameter.

lines generally underground, and under slab.

our neighborhood pittsburgh has radon fans, most outdoors,
temperatures blow zero. fans appear to run fine.

if your selling the home, fan life expectancy will be next owners
problem.

one neighbor here put fan in basement, ran exhaust line up thru
chimney originally used for furnace. it was wierd seeing plastic pipe
being inserted in chimney.
