new construction - dwv tub/toilet question
Hi everyone,

I have a new construction and want to double-check the current setup of a second story tub/shower/sink combo. The layout has the tub on the opposite wall but inline with the toilet so here is what I did initially from left to right ...

2" P-Trap - 2" pipe - 2" to 3" adapter - 3" pipe - 3" horizontal sanitary tee (up for 3" toilet) - 3" pipe - 3" vertical sanitary tee (up for for 3" vent and down for 3" waste).

Distance from the tub drain to the vent is 7 feet.

Is it permissable to run inline horizontally from the tub to the toilet before the vent?

A better solution?

can you draw it some sizes and measurements and then post some pics and if you want it to local code you will have to give your location

where is you sink at

jaydevries 03-01-2013 08:04 PM

you need to use a wye and a 45 if you have the room or lay a wye on its side and then use a 3x4 toilet 90 for toilet

I didn't draw it but the sink is directly off the 3" vent stack

You need to vent your tub trap. Also a y fitting is required for the toilet. You cannot drain any material into a TEE fitting as shown. You also should pull a permit as required for your construction so your home will not be condemned in the future. Ohio is very strict about building codes especially northern Ohio where I inspect for a county.

thanks jaydevries - as long as I reroute with the wye and 45 it then the tub should be okay vent-wise? I just didn't want to revent up and over the outside wall to tie the tub back into the stack. I appreciate the advice.

I have all the permits - unfortunately the original plans you have sometimes change due to the final design of the home. I'm seeking advice and won't have it inspected until it's perfect.

hey ghostmaker why does the tub need a separate vent when a 2 inch is allowed 8 feet to vent under ipc

Not legal any state in the USA that I'm aware of many things wrong. Definitely no way in massachusetts

if the sink is on the vent stack then that would have to be a wye also

Tee is the way we have to do it for fixture arms.
And why 2" to the tub or is it a shower?
