    Hi,

    I'm working on a bathroom and will be adding a double sink vanity that will share the other side of a wall with a washing machine.

    Looking for someone to tell me if they any know areo any code issues with my layout

    It's a rough sketch so feel free to ask any questions. My main concern are making sure there aren't any issues with the 3 sanitary tees on the waste stack that will for both sink drains and washing machine drain. They'll start at the floor and finish around 18" above the floor so that the sink DWV is the right height and the washer trap arm isn't above 18".

    Thanks

    I would check your code on the washer box dumping into a 2" line

    nope.

    nope

    nope

    lol

    that is not going to work, a washer is a suds producing fixture and those sinks will get suds backing up into the sink

    you need to tie into that 2'' line after the washer and by code you have to tie in minimum 8' from the connection
    . i think you can get by with 5' ..

    With all due respect, I don't think that applies here.
    8 feet from the bottom of a stack that has a suds producing fixture dumping in it.
    Also, doesn't typically apply to single family residence.
    Here's the UPC. Couldn't find in IPC.
