I have a few electrical conduits I need to run below grade using those
gray colored PVC conduits (Carlson brand).
I have been connecting those pipes together using regular plumbing PVC
primer and glue. You know the purple primer and the general purpose
PVC cement you use for PVC drains. I just noticed today in the
electrical aisle there is a "specially formulated cement for Carlson
PVC conduits" and the instructions did not mention primer. So I am
wondering, did I make a mistake in using general PVC drain pipe
cement? Is using primer a bad thing in this case?
Second question is about connecting this to EMT pipes. I ran the PVC
pipe below grade and then used a 90 degree elbow to come up to the
inside of an exterior wall. I glued a PVC female threaded coupler to
that and then screw in to that female adapter a male threaded EMT
connector, then on to the EMT pipes. Everything looks good and then I
realized the 1/2" female adaptor and threaded coupler are actually
more than 1/2" deep, and all the furring strips on the inside of this
exterior wall are 1/2" deep furring strips, and now with these
couplers they protrude more than 1/2", how would I lay sheet rock over
this? or do I need to punch a big hole in the exterior wall and then
work in a couple of offset pipes to offset the thicker connectors into
the wall cavity?
