Terry,
The pipe is placed at higher level at the house and at the last tower cables
are in a sweep corner to the cabinet
and the pipe is ended in to a canal with grevel stones where condensation
water can flew
out.This give me also some air ventilation
inside the pipe ! The cabinets have also a air ventilation system in the
walls .
