Hello Everyone,
Hoping I can get some input on moving my washer, as part of a main floor powder room and laundry room (adjoining non-load bearing wall) remodel made necessary after discovering a slow leak due to a baseboard nail through side of bottom plate, The 2" drain pipe was for vanity, and washer/utility. Puncture has been there for at least a decade, prior to buying the house. Floor and a large amount of drywall are currently removed, so I figured I might as well make wifey happy while it is all apart.
I've included my best attempt at drawing existing and new proposed DWV layout, and a pic of the existing drain/vent.
Existing setup has the washer downpipe sharing the utility tub p-trap. During my reading up on this, discovered the downpipe wasn't to code, as it was hidden inside of old utility tub cabinet, substantially below the top of the washer tub. As well, from what I understand, washer downpipe and onward through drain are supposed to be 2" now. We would like to move the washer from the side wall in corner nearest doorway to the far wall that is opposite doorway. Also, existing supply lines for utility tub and vanity will be moved back into the bottom plate, theycurrently come up a few inches into the room.
My intention is to use a washerbox with 2" drain at the recommended height, keeping downpipe and p-trap with cleanout in the wall with an access panel to the p-trap, keeping p-trap at specified height. Wall is 2x4 construction. Then use a wye +45 fitting into the 3" pipe from toilet, that passes pretty much underneath this point. The 3" pipe turns from horizontal to vertical onto the top of the stack. There doesn't appear to be any other venting other than the 1 1/2" that comes up from the vanity/utility drain, which goes off into the joist space. Presumably joining up with the main stack somewhere, and out the roof. Two story home.
As for the venting, I'd rather not cut holes through every stud in the wall to get back to the exiting vent. Pretty sure this is against code, so I plan to go up the stud cavity and then along the ceiling joist space to meet the existing vent.
My questions:
1) Do I have everything correct?
2) If so, is venting sufficient? Some conflicting reading indicates that I might have too many DFU for the 1 1/2" vent
3) A combo Wye or wye + 45 is the correct fitting to join the 3"?
4) A Tee would be used where the vertical existing vent and my new vent pipe come together?
5) As I write this, I realize that I haven't even considered if there is anything special regarding bringing hot and cold supply to the washer. Can I just branch off the existing supply lines that feed the utility tub?
I'm in Ontario, Canada. Once I'm done designing this, I plan to reach out to the city and verify if a permit is needed for the work. I'm assuming that it is.
Thanks in advance for any feedback,
Rob
