Heel inlets are not approved on a toilet.

706.4 Heel-or side-inlet quarter bends. Heel-inlet quarter bends shall be an acceptable means of connection, except where the quarter bend serves a water closet. A low-heel inlet shall not be used as a wet-vented connection. Side-inlet quarter bends shall be an acceptable means of connection for drainage, wet venting and stack venting arrangements.

Not Approved.

Just curious about this, because I seem to see it this way everywhere I look. The way I want to install my plumbing, my toilet is at the end of the line before it ties into the main septic line, with the vent for the toilet being supplied from the lav upstream. Almost everywhere I look online I see that the toilet is vented downstream of it. I am just curious as to why that seems to be so common vs what I am doing being so rare? You all say what I am doing will work to vent my toilet, and I'm sure it will, but it is just a discrepancy that is nagging at me. Thanks again!

Can you reference a post or drawing that shows your layout?
This thread has gotten pretty long and I've lost track of your design.

Chronojosh think about it a bit. Your toilet has feces a solid going down the pipe. This flows in the vertical on the outside of the pipe. How long do you think it will take to fill that pipe coming out of the end of that 90 to blocking the up stream drains. You asked for a legal good practice layout. It was given to you. What you do is up to you. Personally I hate snaking drains. If you are inspected then using the above heel outlet 90 is a rejection if your inspector is a good one.

I do appreciate your advice, and I am very grateful that you have taken the time to answer my multiple questions. I won't be using the heel outlet, and using one was never my intent. I just wanted to verify one final time before I start cutting through the piping that my layout did have proper venting for all the fixtures and would work properly. Especially after seeing how toilets are more commonly upstream of vents. The wye 1/8 on its back will be what I am using for the toilet, because I have the room for it height wise. Thanks again for all the great advice and help.

Buz42812 fitting is also fine to use. As long as it is a high inlet.

So I passed my inspection. There wasn't much to it which surprised me. But after the inspector left, I started filling the trench in and realized I screwed up. The line from the sink to the shower sits too high. When I pour the concrete to patch the trench, it will be directly on top of the pipe. I know the concrete may crack, but I will be insulating the floor and putting down an isolation memrane before I tile. Should I continue on or am I screwed?

It will be four inches everywhere, except over the top of this part of the pipe, it will only be 2. The section of pipe that is too high is about 12" long.
