Add elbows to condensate piping?

Chuck_17

A two pipe system. There are some condensate pipes serving second floor radiators that come down through the first floor exposed in the corner of the room. The owner wants to conceal the pipes in (interior) walls. Does adding a few elbows to the vertical condensate pipes raise any concerns?

The biggest concern is to make sure any horizontal sections continue to have some pitch in the right direction. Using 45's might be better than using 90 degree elbows. I'd be more inclined to box them in rather than move them.

Two pipe condensate lines are less likely to have drainage problems such as you would have with one-pipe returns, because there is no steam in the two pipe returns (if the traps are working properly).
You could certainly use some angles to move the pipe closer to the wall and out of the way, but are these pipes so far out from the wall that they are in the way?--NBC

They are close to the wall but are offensive to the eyes of the frat brothers. The sprinkler piping will be harder to hide.

I also would insulate and box them in... This is for a frat? They find piping offensive?
