What are the out of plumb tolerances for toilet flanges and tub spouts/trim? I have recently had a plumber install the rough in piping for my toilet and and tub spout & tub trim kit and I was unhappy with the results (see photos). Although it is not glued yet, the toilet flange in the off-vertical sewer pipe is off horizontal by about 4 degrees (which amounts to almost 1/2")whereas the tub spout/trim kit is off by about 7 degrees! I have lost faith in my plumber so what are my options for installing the toilet flange? I am guessing that glueing the flange and screwing it tight might overstress the existing pipe and joints. Thanks for your help!!
