Washing machine/sink drain and vent

garrettgjp · Jan 21, 2013

I am a new home owner and this will be my first ever DIY plumbing project.

My washing machine drains into the laundry sink and I am wanting to have it drain into a seperate pipe and figure out how to vent it properly as well. I have included pictures of the current setup, any suggestions or advice would be greatly appreciated since I am not sure how to go about this correctly.

The photo shows an S-trap which is illegal, because it self-siphons. Also, it appears to drain into a drain stack, and therefor there is no vent.

First you will have to cut out a section of the cast iron and install wyes for the new drains. Then you will have to run a new vent from the basement up through the roof. Unless you are well equipped and quite skilled, this will not be a very good project for you to learn about plumbing.

Above fitting #5, there can be no other fixtures draining into that stack to have that vent setup be proper?
