Venting questions


Ok, so I know that theres quite a few of these venting questions out there, but I cant seem to find the question that I'm wondering.

Heres the deal, I am turning and existing bedroom into a laundry room/office. Our house was never plumbed for a laundry room. The plumbing woudl be on a wall 7ft from the main plumbing vent.

From what I've gathered, is that to tie into this vent, i need to be within 5ft or I have to run a new vent through the roof. Correct?

If so, Beings this doesn't have a toilet on it, I should only have to run a 1 1/2 in vent?

I live in WA state

Any help is appreciated.

A washing machine requires a 2" drain line and trap. The vent size is 1.5" Maximum trap arm length is 5' (distance from the trap to vent)

Pretty much what I was meaning....but I guess I wasnt too clear. Yes, I knew that the drain and trap had to be 2in...just want to make sure that I was reading everything correctly...

Venting questions


Are you tying the laundry into a vent pipe, or a drain stack? Into a vent is a bad idea, less you want suds all over the place. Backing out of sink drains and tubs and stuff.

Venting questions


is there another floor above the floor you are installing? if not then you can back vent to the vent without going through the roof or ceiling.
