Trying to relocate a drain- I need to deviate like 27 degrees from the original direction of the drain. What are my options?
I would use a 22-1/2 degree elbow and flex the pipe if they won’t do it because of the short space a fernco or no hub in the middle will give a couple degrees they are not designed to be flexed but a slight couple of degrees will work if you can’t make a small bend with heat a hair dryer may be enough with abs to get the extra bend if you don’t want to use a fernco. I would never use the corrugated flex pipe and especially not under a slab. But the elbow and a bit of bend in the pipe should do it.
