New Bathroom / Laundry Room in the Basement

[zaius]

Hi all,

I'm trying to layout a new bathroom/laundry room in the basement. I will be hiring a plumber but I would like to know if my layout is feasible. I'm located in Toronto, Canada.

Above the location is an existing kitchen drain, giving me access to a copper vent and drain. Currently, there is nothing in the basement other than a laundry tub connection on the 1.75" CU.

1) Is my venting ok? Can I have this many fixtures on my existing copper vent? Should I convert the copper (vent and drain) in the basement to 2" ABS?
2) Can I have a toilet beside a washing machine? Will there be any issues?
3) Anything I should be aware of?

Any guidance would be greatly appreciated.
Thanks.
zaius.

edit: uploaded some sketches. Cheers!

Close, but no cigar. draw a floor plan with walls and someone can help you.

Sure thing. I drafted up a couple additional sketches. Hope this conveys what I'd like to do.

This is how I would do it for a shallow drain, if your existing drain is deep then you have other options.

While building your basement laundry room, consider a laundry chute.

Thanks James!

Is this what you are suggesting (attached)? Will the 1.5" copper vent be able to handle this many fixtures?

I can't... the main floor is already finished. I would have considered it though!

Thanks James. Is there a reason for the change? Is the sink preferred to have the wet vent than a shower?

 

[James Henry]

If that is a lavatory then your last drawing will work , but your calling it a laundry sink which is different and in my code a laundry sink can't wet vent a shower, only a lavatory can so if that is a "laundry sink" then the shower needs it's own vent.

 

[zaius]

Awesome! Thanks, yes it'll be a laundry sink. Now I have a good understanding of how much of my basement floor needs to be broken. This is going to be a lot of work.

vent for toilet and vent for floor drain needed 2 inch vent I belive .
Dont know if the w/c can be in open room like that with washer /dryer my guess is its ok a privacy door would make it a bit nicer

I don't have many options in my basement given the window/plumbing stacks/etc. I'll probably stick up a half or full wall for the toilet so it's not that bad.

Well, I did some exploratory digging and it seems like my clay drain is not going straight to the floor drain as I first assumed.

Before I randomly break up my floor for the plumber, is there a suggestion on how I can connect the shower/laundry sink/tub as it is sits so close to the existing drain?

Also, is there a reason why the toilet drain is drawn close to the wall to connect to the vent? Can I just extend the vent horizontally in the ground to connect to the toilet drain instead?

Thanks so much!

 

[James Henry]

You need to expose the drain at least past the floor drain. Theirs no way to design a plumbing plan if you don't know where the main drain is.

 

[zaius]

Ok. Will do and will report back.

Maybe its just the angle, but that looks like a pretty thin slab.

A dry vent takeoff can't be flat, it has to be taken off at a rise of at least 45 degrees above horizontal. So the takeoff is near the wall in order for the vent to be able to rise into the wall without going horizontal at all.

As to whether you can rise a little, then turn horizontal below the slab, and then turn up into the wall, in the US that depends on which plumbing code you are under. So you would need to check your plumbing code.

Thanks Wayne. That makes sense.

I got more digging done today. Things that I've noticed:

1) I went "past" the floor drain and couldn't figure out how the floor drain connects into the clay pipe. Would it be at a 45 deg angle? I will probably dig around the floor drain later this week to see at what angle it connects.

2) From the vertical stack, some sort of metal connects into the clay pipe. I'm assuming it's iron?

3) I also noticed a 2"? plastic fitting right where I stopped digging. I'm assuming that's a clay coupler.
