I'm doing a owner build, and want to try and set these precast scuppers myself.
I have 1 1/2" stubbed behind my wall, and I need to have these plumbed and set before I can backfill behind the raised rear bond beam, so I figured I'd do it myself if I could.
The best I can figure is:
cut the rebar
center and level the scuppers
plumb a 90 pointed up in the bottom rear of the hole. The hole is 2" larger than the scupper, and the bottom of the scupper is 2" thick, so that gives me 4", which is enough room to conceal a 1.5" 90 degree fitting.
fill around and behind with cement.
What obvious detail am I leaving out?
Is that how I should plumb it?
Is there a particular kind of cement mix/grout I should use/need to use? A minimum thickness? Any advice for someone with plumbing experience, but a newbie at the rest?
Should I just bite the bullet and hire a tile guy to set these for me, or is this a task that the average guy can handle?
Here's some images of what I've got going.
