No crap...and I hate BEING that guy to them! But when the plans, specs, and 3 different details specifically outline 4" individual connections to the branch, and you install 3" stack san tee's into a 3" combo when it should have been a flat 4" combo into a 4" branch... 48 times.....well, shit's on you to read
There's a reason these guys were $54k LOW on this job
Holy shit sucks for them.
So what is it for?
