Hello, This is a great forum. I was wondering if you could offer me some advice?

I am converting part of my garage into a bathroom. I will be busting up the concrete and running a new 3'' pipe for the toilet. My question is regarding the vent. How far away can I be really? There is an existing 2'' vent about 7 feet from where the toilet is going in. I would need to come up off the waste line to the ceiling and then go over seven feet to tie into the existing vent. A sink and the shower will use the existing vent and the existing drain line as well. It was for a washer...

I really don't want to put in a new 2'' vent! I do want the toilet to flush well though of course! This is not going to have an inspection... Also, Can I put the toilet in without a cleanout? The new 3" waste line will travel about 20 feet at 1/4 inch per foot slope and tie into the existing stack that does have a cleanout.

Thanks for any help!

Thanks in advance for any help.

If the washer line and existing vent are tied into the 3" drain line then you are already vented for the toilet. Tie the shower drain into the lavatory drain and the shower is wet vented also. This should complete venting for the entire bathroom group.
Good luck, Tom

Nobody ever regretted installing a cleanout. On the other hand, if the toilet has an angle stop at it, shut it off, undo the compression fitting, remove the 2 nuts on the flange bolts, and pull the toilet off. With a new wax ring, it goes right back together once the drain is clear.

Thanks for the help. Actually I was planning (if possible) to not tie the sink and shower into the new 3'' pipe. They are located across the room and that would require a lot more concrete busting. The shower and sink can use the existing 2'' waste that was for a washer.

I am trying to use a new 3" waste for toilet but take advantage of the 2'' existing vent across the room. Would this work and how far away from the vent can I be really? My book seeems to indicate 6'... Can I push this? Is this a code thing or would it really not vent well? As I mentioned above, I would need to travel up from the waste line, (in the wall) to the ceiling ( 8') and then across (7') to tie in with the existing vent that goes through the roof shortly after I tie into it.

This should require the least amount of work if it is possible

Thanks!

You're going to like my reply. You may keep your lav and shower on the same drain line and vent. You may also revent the toilet back into it. However, (and here comes the part you're going to like) the 8 foot up and 7 foot over doesn't count for jack. The toilet vent begins where you tie into the 3" drain.
You have options here, you may tie the vent into the 3" main or if it's handier to keep the vent tie in point close to a wall you may use a closet bend with a heel or side inlet and vent from that. Good luck, Tom
