This radon job went from being a relatively simple one day project into an intensive two day project, after the client requested that we hide the pipe in the bathroom wall where it passed through the second floor.
I first drilled a 3 5/8" hole from the basement through the first floor into the back of the 2nd floor bathroom closet, for the standard-sized pipe to come through from the basement origin. It was from that point that I needed to angle the pipe backward, and run it straight upward inside the walls to the attic. It looked like I would have to drill a hole downward from the attic, at a point exactly between the walls, or risk putting a hole in the second floor ceiling into the bathroom closet or adjoining bedroom.
This turned out to be an exceptionally dirty job, due to the summer heat making me sweat profusely, which caused the loose insulation material in the attic to stick to me, which I had to search intensively through to find the right spot to drill through the attic floor.
I finally determined the target point by taking a measurement from the air conditioning duct that ran up the side and rear of the bathroom closet walls to the attic.
I informed the client that there was not enough room for the standard sized radon pipe, but they asked that it be done anyway, if at all possible. I went back to Home Depot, and finally found a flat oblong-type pipe, with the same air-flow rating, that would most likely fit. Back in the attic I slowly fed the flexible piping down through the hole to the other hole in the back of the closet near the floor. This entire process took the rest of the day, so I had to return to finish the job the next day.
On day two, I connected the inside-the wall pipe to the standard 3" pvc piping on the first and third floors, hooked up the fan in the attic with the roof penetration, and finally was done, a solid, two days of radon work!
