I need to move toilet line away from window to have full access.

Question: can I run through joist or remove 90 deg and install 2 x 45 deg? Any easy solution?

Hello Lawrence,

I don't see why not. If you have to go through a joist I would suggest reinforcing it as much as you can before or after you make your hole.

Thanks. I've been doing research on this but seems like I get the same results. 1 says no one says yes. lol. Moving the toilet is not an option and yes I believe that going g through joist will work with the proper reinforcement. And I had LHP out to look at it 3 years ago and he took 1 look and said can't do anything with it.. turned and walked away 125.00 later???? Really. So anyway I was told that replacing 90 with w 2- 45deg is ok. Will this give better flow?? Does seem like a easier fix.

I think you have a short 90 there. You might want to try a long 90 instead of 2x45.

You have heard from different company's saying yes you can and no you can not. If you want a absolute answer to your question call the city and have an inspector come out to look at the situation and they can give you the correct answer as to code if and what you can do.

I think what you want to achieve is to raise the toilet drain line to above the window. To do this you would have to remove the toilet and then re work the drain line so it sits inside the joist space. you could then incorporate some 45 deg elbows and get below the joist and then hook back into your stack.

Thank you all for the input. As far as I long 90..sounds good but it would put me in same predicament. .and yes I need to raise it above window or run it down joist farther and then come out under joist. My issue with all of this is that if I build a header it will cover part of the window..so I need to move the line?

Hi Lawrence,

I would look into replacing the entire section of 3" drain pipe that the toilet ties into. Looks you can run it over and tie into the main there and keep the toilet drain inside the joist. You may need an inside fit closet flange like this to keep it high inside the joist. https://www.homedepot.ca/en/home/p.closet-floor-flange-3-inch-inside-fit-plastic.1000174144.html.

You're not running it far so you should be able to get enough slope. Access maybe a bit of a problem above the fuse panel. Difficult to tell from the 2 pictures. Same idea as Don.

The other line is main bath toilet..but yeah its 4" I believe and that's exactly what I might do just run it further down joist and over.

Hi Lawrence,

It looks like you could reframe this section of the floor to achieve what you want but this is not an easy job. I would recommend you contact your local Design Builder to get this done properly.

Good luck with your project.

Job complete, thanks to dons plumbing and heating.. (terry), great job and thanks again. All worked out well just moved the Y back and the rest fell into place..400$ touch all in but we'll worth it. Now I can get on to cleaning up electrical mess and put a ceiling up.
