I'm using a 4x3 closet bend close coupled (with a 1" stub of 3" pipe) into the short 90 elbow, laying on its side, into a 45 street el, also laying on its side, into a 12" horizontal run of pipe that ties into the wye on the stack. Can I use that short 90 elbow in the horizontal position in a toilet drain line? Is the 45 OK on its side? It's all PVC if that matters.
