Venting help


Although I've been lurking around and finding great information in these forums for my recent home addition, this is my first post.

In my new addition I will be moving my washer/dryer to a different wall from which they currently reside. I am wondering if the venting I have drawn out on this diagram will be correct for the layout pictured? Does the p-trap need to be moved immediately below the new washer box or can it stay where it is? Is there a better way to handle the venting?

Any help would be greatly appreciated. Thanks guys and great info!

the trap will need to be cut out and moved closer to the fixture. You'll also need a vent for the trap closer. My code for 2" pipe is a 5' trap arm. Your code may be different. If you need a new vent, run it vertical until it's above the washer box, and slope it back toward the drain. The rest of the pic looks good

So something like this would be correct? Sorry about the sloppy drawing.

Thanks for your help.

Thanks for the help. So basically the code doesn't say there has to be a vent within a certain distance of the actual drain pipe, but just the trap?

Correct, your venting the trap, not the drain. The distance varies depending on the trap arm(the pipe between the drain line and the trap) diameter. In your case its 2". This is based on my local code of course (UPC)

If that line comming thru the floor on the left is a vent for something below the floor you can't tie it in the way you have it

I believe its the original auto wash drain and he's moving the box to another location. No other fixtures were mentioned in the post.
