Load bearing wall with drain pipe


Hi, I have a load bearing wall that I would like to remove and replace with a 12 inch header. My issue is that in the current wall is the drain from the upstairs bathroom. The drain runs down inside the bearing wall I would like to remove, the drain is about a foot and a half from where I need to move it. My question is if I can cut a hole in the last ceiling joist so I can run the pipe through the joist ? I have found some joist reinforcement that will ask allow me to do this, just want to know if anyone has any experience with something like this.
Thank you,
Tom

Avoid cutting holes in joists if you can. If you are going to put a beam under the hole you may be able to get away with it. Keep the hole as high as you can in the joist. When a joist sits on a beam there is an area of the joist that is not structural. For example, I had a beam once that would have stuck out through the roof because it was too tall. I was able to cut an angle on the beam so that where the beam sat on the wall it was only 3 1/2 inches tall and then angled up the 11 1/2 inches that was the full height of the beam. There were engineering requirements that specified what the angle that I cut could be and how far down on the end of the beam I could start the cut. It would make sense to me that you could drill a hole in this area of a beam or joist.

Is this getting inspected? You should definitely talk to the inspector before you do anything like this.

I have never used a joist reinforcement for something like this so I can't comment on that.

You could also 'head-out' the plumbing. I have had to do this on houses where the framers didn't pay attention to where the toilets sit when they framed the house and there was a toilet sitting on top of a floorjoist. You cut the joist out on either side of the plumbing. Then you make headers for the cut joist to hang from. The headers are short floor joists that hang from the joists on either side of the cut joist. Use glue in the hangers and make sure they are tight or they will squeak.

Good luck.

It might help if you mentioned the size of the joist you want to put a hole through and how big the pipe is.

a rough drawing of what you have and what you want to do would really help and by the way, 12" header is not a cure all. How much of a load will it be holding?
