Hey everyone,
I need some advice regarding a toilet drain. So far I have it setup as pictured but it has been brought to my attention that it may not satisfied California Plumbing Code in terms of cleanout.
Image link :
The 3" drain goes from the toilet flange into a long sweep 90 then into 2 45° then another long sweep 90° into a combo with cleanout.
The 2 45° are needed in order to drop the drain line to install the toilet vent. There is not enough space to slope the 2" vent if the drain if not dropped.
Also all the piping will have to be concealed with drywall in order to satisfy fire code.
But do I have enough cleanout on the line in order to pass inspection?
Any advice on what s missing or what needs to be changed will be greatly appreciated.
Thank you

Thank you for looking at my issue.
I am just really concerned that an additional cleanout is required at the toilet flange.
The line from the toilet flange to first cleanout has 270° in direction change before the first cleanout.
I didn t show the shower vent for claritiy. it is right after the P-trap. The 1 1/2" vent goes up to the attic and ties into the 2" toilet vent.

codes vary across the country.. my code says if a fixture can be removed to permit access to a pipe for the purpose of snaking, that is OK.
if you are worried, put a cleanout tee in the vertical section between longsweeps at the lower end.
you can clean both directions , up towards the toilet and down to the sewer from a cleanout tee.

Thank you. I thought about using the 2 way cleanout tee just in case. I can t find anything in the California Plumbing Code about removing toilet for snaking.
Also, do vent line below FLR can use regular 90° or long sweep 90°? The toilet vent will be running horizontal for 3 feet ( 1/4" slope) before turning up in the wall. A regular 90° would give me more room to play with.

Here in NC no cleanout would be required for that drain. A long sweep 2 " 90 would be required on that vent as it's below the flood level. You can use a 3" regular sweep 90 where that drain turns from horizontal to vertical if you want, it's showing a long sweep on the picture.

is it possible to move the toilet vent down under the shower? you can have the toilet vent up to (again codes vary) 8-9 feet away from the toilet?
this way you can drain the shower into the toilet vent and the toilet vent can go straight up a shower wall.

I thought about it but the closest full wall of the shower will be about 11 to 12 feet from the toilet. So I doubt it will work code wise. I believe it is 8 feet to the vent for toilet but I would have to double check.
However, I forgot to put in my drawings that there would be a vanity sink drain going in between. It is about 3 feet from the toilet.
Could I use the sink drain as a wet vent for the toilet? The toilet drain is 3". The sink drain would be 2". Then 1" 1/2 vent combine to the 1" 1/2 vent of the shower to the roof.
This is another option if I can get the sink drain around the floor joist into a 3x2 Combo

you can absolutely use the sink drain as a wet vent for the toilet and also get the tub into it if possible. it must be 2 inch and stay 2 inch all the way thru the roof or to a common vent stack.

I thought only the wwt vent section had to be 2" between the main drain and sink p trap. Then 1 1/2 for the rest.
I can't find anything in the code about it.

my code state the wet vent and its extension must remain UNDIMINISHED in size to its termination.

In CA, 2" minimum vent for a toilet, wet or dry.

Steve,
so if my toilet has a 3" drain and is being wet vented by the sink downstream, the sink would need to have a 2" drain and vent. Correct?
