I have a toilet rough-in that was done by a plumber when I built the house 35 years ago. I never hooked up a toilet due to building dept not allowing half bath due to a slopping ceiling which never made much sense to me.
I've recently decided to install an Ultramax. I notice there wasn't much slope to the drain line and was thinking I should probably put a little more slope in it. The copper line is in the way to just pull the drain line down a bit. I can move the copper or just have the drain go under it. That's not a problem either way. My concern is the way the plumber vented the drain. In the pic you can see the vent and drain are horizontal for about about 4' before the vent goes up to the roof and the drain goes down. The third pipe on far left is for venting a bath behind the wall on left. They connect in the floor above about 3' from the floor before one goes up through the roof. Will this work? If it's not to code, what is the reasoning why this shouldn't be done. The toilet flange is attached directly to elbow on the upper side of floor.
Thanks.
