RE: SB: air Cooling tubes

["Wil Maertens" <biofab@ricestraw.com>]

on a SB project we have 180 lineal feet of 48" galvanized corrugated culvert
under the house and off to an out building. very anxious to scout for mold
and other.
in the pipe line industries they have special device called a "pig" that
scrubs pipe line interiors. one of the largest manned pigs i knew of was
fabricated from a Mercedes sedan chassis.  Wil



The pipes would be much more maintainable if they were 18" ID.  Lets see, no
PVC, how about concrete pipe or asbestos cement pipe?
