What a great site full of great info. I already learned a ton just by reading and the pictures that professionals have posted.

I'm deep into my addition and about to finish things up. I have to tie the new plumbing into the old. I have a guy who will do the yokum for me connecting into the old cast iron but I need to get it there.

Can someone please take a look at my drawing to determine if it is the correct venting.

I am trying to utilize the vent I installed for my island which is in the addition to properly vent the washing machine and a crapper as plans have changed several times over the few year long project.

Any advice is appreciated and my skin is think. Thanks JR image.jpgimage.jpg

To start with, all of your vent take-offs must be vertical, and they can only go upwards, never down. The island can use a properly plumbed loop vent, but you have not accomplished that either.

And you don't need a p-trap for a toilet. The trap is already in the toilet.

I know it probably seems like it all makes sense as you have done it, but how you have done the venting indicates that you haven't been schooled yet in some of the relevant principles of venting. Here are two excellent handouts that explain a lot. One has good photos of it being done properly, as well as rules and tips; the other has more specific rules and a lot of good drawings. Together, they should give you an idea of how to do the venting for each fixture, and details like how high things have to be (e.g. for the washer standpipe, etc.). Give them a review and come on back. We'll look at the next draft.
