Re: Can toilet branch be downstream?


The turns for the toilets from horizontal to horizontal are made with a wye and 45.

Re: Can toilet branch be downstream?


So I've spent most of the afternoon trying to get smart on this and redrafted my design (below). Please let me know if this looks okay. Also, I don't see any 90 degree connections for 2" to 3". Do I use a 2" to 3" combination wye and cap one end? How do I do this?

Re: Can toilet branch be downstream?


You have one toilet 2 lavs and 1 tub now. Is that a shower on the top left?
If it is You run 2 inch to the shower Vent with tee on back in wall. Continue 2 inch to the tub. 1.5 inch to the tub trap. Max 5 foot from 2 inch. Use a wye to pick it up. once at the lavs you will need a 3 by 2 wye with a 3 by 2inch bushing in the end of the wye to the tub. The 2 inch branch to the lavs into your wall behind the lavs with either 2 stacked tees in vertical one for each lav or a cross. You will have to vent off the top again for these lavs.the three inch will need to go in front of your toilet use 2, 45 degree fittings to make the turn. install a wye for the toilet with a 3 inch 90 looking up for the toilet flange.

3 inch must go all the way to the lav pickup on your wet vent.


If the upper left is not a shower. You need 2 inch to the double lavs. 1.5 inch to the tub trap. Again run infront of your toilet install a 3 inch wye flat with a 90 coming up for the toilet. You can bush down to 2 inch to the lavs and the tub.

You must permanent cap all things upstream of the tub because they are now dead ends. Your vent is now coming off the lavs.

Try drawing a line isometric it would make life easier to interpret your work. with pipe sizing's.

Looks like your going to have to get up in the attic and redo vents.

This entire thread is a very good example of why plumbers in most states are required to be licensed which can take 3-5 years of on the job training plus schooling. most people think you can just connect some random pipes together and water will drain out the bottom but there are a lot of physics involved.

This is a ridiculous statement. If "most people" think what you say, there would be little demand for plumbers. And any DIYer using this chatroom doesn't think that either, or they wouldn't be here.

True ignorance is a person who believes they know what "most people think".

This is a DIY chatroom. The purpose is for the novice to learn from the expert, not for the self-righteous to spout baseless opinions on how stupid people are. You're painting DIYers with a pretty wide brush...feel free to leave me off your list of people who don't appreciate what it takes to be a plumber. I don't use this forum because I'm stupid. I use this forum because I'm not stupid.

i am not calling anyone stupid knowing the extent of your ignorance is exactly what i was trying to point out in this situation. there are a lot of little things that can go wrong with plumbing and when you take on a project as big as plumbing an entire house it is unrealistic to think you can learn it all online and not screw some small detail up. Even after an apprentice has been going to school for a few years and working on the job at the same time they make mistakes that is why they have licensed journeyman to supervise them. this was not meant to be a personal attack.

Re: Can toilet branch be downstream?


I stopped taking things personally in this chatroom a long time ago. I really don't care if anyone doubts what I can do. The fact is that the naysayers have no idea how much time and effort I spend trying to do things right. It may take me a month to do what a professional can do in an afternoon, but my final products are solid.

I just don't like it when people use my posts to tell me and others what we are thinking. Assumption is the enemy of understanding.
