In need of advice basement plumbing rough in DWV

[James Henry]

To be clear. The wet vent ends at the point that the toilet enters the drain. You can tie the floor drain into the drain past the toilet. At that point it is no longer a wet vent just a drain line.

I cleaned up the old piping to give better idea of what’s where

I think this is what your trying to accomplish, if it is then you can use the first drawing that was suggested to you.

 

[Jeremy7835]

So if I plug them both then I don’t need to vent that drain?

 

[James Henry]

OK, I've hit my limit. Don't take offence because I don't mean any. their are too many variables in your plumbing system that I can't see. it's like someone asking me to look at their plumbing but I can only look through the keyhole of the door, I'm afraid if I continue I'll give you the wrong advice. From this point forward I want you to forget everything I've suggested this far because now I'm having second thoughts. Here's what you need to do and it will benefit you the next time you go on a forum for advise.

1. expose all the plumbing that your trying to get advise on, clean the area.
2.take pictures of everything in 360 degrees and the vents above your head.
3.take the time to make a detailed sketch of the existing and proposed plumbing drains, vents and fixtures and include dimensions.
4. That's all.

Hey pal I didn’t beg for your advice you posted on your own free will. Sorry your upset lol

 

[James Henry]

I'm very calm. I'm sorry you took it the wrong way. if you do what I suggest you will be surprised at how many people will jump in to give their advice.

I’m sorry James I think this Hvac guy could throw some pipes in the floor and it would work I just really wanna do it right! Didn’t mean any harm.

 

[Jeremy7835]

My exsisting drawing doesn’t show but this was a finished mechanical room / bathroom. Both furnace and water heater were incorporated into the bathroom and not even I 5’7” could stand to take a shower in there.

 

[James Henry]

Good job on the pictures, now I can see that their are no existing vents, they used the stack to vent everything. Did the fixtures drain without any problem? The first thing I would do is strap each side of the stack to the joists for extra support. do not remove any dirt under the drain line accept in areas where you need to work. The bad news is that your state does not allow " AIR ADMITTANCE VALVES", so theirs no easy way to vent everything.
I propose you cap off the old shower and consider moving your fixtures to the other side of the room for better venting. Anyone approve or disapprove of this diagram, speak up.

I’ll never get a vent up the exsisting stack wall because it’s full of wood!
That’s the reason to swap sides and put fixtures on other side so then I can run up in front of chimney with the vent and connect to 3” cast iron in attic

Or can I use the main stack?

That changes everything. Does it have a vent to tie in above the fixtures on that floor or are you going through the roof?

 

[Jeremy7835]

I was going to run to attic and attach to cast iron or I can go through roof as well
This is a 800 sqft home all that is above is the main floor bath and you can see those drains in my pictures and there are no vents it uses the stack
Kitchen is on other side of house and has it’s own vent

If you can pull this off its the best scenario.

 

[James Henry]

Bottom line. theirs the old way to plumb and theirs the new way. sometimes the old way works just fine. it's your house and whatever works for you is your decision.

I think I can pull it off! Looks good sir! Planning to get to it this weekend I’ll post pictures soon
