Finally ready to rough in my shower and found a pipe in between me and my drain location. White pipe is about 1.5” above the black drain line. I was thinking coming out of the black line with a 45 rolled up and then another 45 to make the 90. Come just over the top of the white and located the trap directly under the shower drain. There would be about 6” horizontal from the trap before jr dropped down to meet the drain line. Not sure if this would be considered an S trap? Could located trap where black pipe is and pipe over to the drain but I know that’s not preferred, or maybe not even allowed. In Alberta Canada and it will all be inspected…thanks!
