I did have a licensed plumber out once before I started digging around the "main inlet". I found the terra cotta and all my plans had to change again. Too embarrassed to ask him for another trip. I'm running out of gift cards too. Anyway, here's what I've come up with; maybe my layout will make it more self explanatory:

D.) original position of toilet.
B.) air admittance valve.
The red dotted line is the terra cotta line. I don't want to move this. I'd rather keep the toilet on this wall and move preferably to where it is in the picture.

Relocating toilet flange and main for basement bath.


I didn't think of adding venting to the lav and shower so this diagrams shows all connected with the AAV. I hope this works.

I'm guessing someone will think this is out of code with the AAV but I've heard there is nothing for basement baths around here. Anyway, I plan on running this "final draft" by my plumber before beginning work. I'm tired of revisions and I want to be prepared before putting it up for inspection.
Can I get someone to at least believe this might pass, short of running a vent to the main stack; is it ok if AAV's were with code? Sorry it's not a real plumbers diagram; I just wanted something neat that gets the point across; please tell me if something is un clear or if you see any PITA stuff. Thank you.

Can I get one more inspection on this? Hopefully this is the final one. Thank you for all your help.

What you need to do is install a 3 by 2 y as close to where your drain comes in as you can, Then use a street 3 inch st 45 and reg 45 to turn the drain to where your putting the toilet.

Now off the 2 inch from that 3 by 2 Y add a st 45 and take it clear to the wall behind the shower and turn to the lav with a 2 inch 90 then Add a 2 inch y with the branch aimed at your shower drain with a st 45 . Place a 5 gallon where your shower drain will be and drill a hole through it to get your pipe into the bucket. The other end of the Y will go to the lav which you will need to vent with an AAV if allowed by local code. Easy stuff

Pour the floor build the wall then install your shower trap on center for the shower base and install a 2 by 1 1/2 by 1 1/2 tee to pick up the lav in the vertical and an AAV about 6 inches above it. Install a heat register grill that can be easily removed so you can replace the AAV when it starts stinking.

Have fun


This is to IPC

Make sure your hole for the bucket is on the high side so the trap will not hit the bottom.

Adjust above fittings to 4 inch if needed.

What you have drawn is a dry flat vent and is illegal. You cannot have any vent that is horizontal below the flood level rim of the fixture. It is prone to blocking and is not cleanable. What i described is called a wet vent when it blocks your shower or sink will not drain you will clean the drain and restore the vent.

Here's my imagination. Are there fittings like this? Will this serve as a wet vent to the lav and shower??

Same problem It will clog and is illegal. There is no such fitting that is made as you have drawn it. You also can not drain any fixture into a tee filling on its back.

Ureka. I found this after searching some threads on "venting". I'm betting this is the answer to a lot of toilet proper venting questions.

My limitations are mind boggling. I also have a French drain on the other walls which could get in the way for proper venting.

I'm having trouble picturing this. Is there a basic sketch you could throw together? I'm planning for a tile shower about 42" wide by 36" deep. Not sure if the 5 gallon bucket is for setting the drain or something... There will probably be a wall between shower and lav to provide a place for the AAV. That might be the only reason for the wall. Would rather leave it open(with no partition wall) but might have to place the valve above the tile with vent...why not? Also won't have access to plumbing yikes.

The 3" pvc will give me more wiggle room. I need all the room I can get with the French drain, over head I beam, and repositioning of the toilet keeping everything very tight.

You should really consider getting a professional plumber in to rough this in for you, considering how you placed that double Y. You don't want trouble once you replace the floor.

Does this look like a good layout/arrangement?

Remove the AAV on the toilet and the shower and your good to go. Place the shower trap directly under the drain. Run 2 inch to the lav. 2 inch to the shower. Use a 2 by 1 1/2 by 1 1/2 tee to stub out to pick up lav trap and aav on top of tee...

Since I'm removing the AAV at the shower, I can change the angle on the shower branch. Not sure where to put AAV relative to the faucet...I'm guessing it has to be above level of the p trap and then might as well go above sink top level in wall behind or in mirror/medicine cab or ?

Thanks for keeping my thread alive ghost.
