New home construction - Any plumbers in the house?

[greenmojo]

I've been building a house up here in central Washington state now for the past 2.5 years, and am working on DWV at the moment.

I have a few simple questions and was interested if any plumbers or people in-the-know wanted to chime in and help guide me?

I'd like to post a few pics and get some feedback on whether this is right, wrong, good, bad.



This is a double vanity in the children's bathroom. First, does it look okay? and second, if the vent pipe was to rest in the back against the sheathing, is that a code violation (other than becoming a possible pin cushion for siding nails)?

Thanks,

~Moses

Don't know what your codes say, but above the "T" is air only, and nails won't matter. Pitch looks good.

Remember, your horizontal runs only need a slight pitch, and need a re-vent when the pitch length exceeds the diameter of the pipe. I'd also put Y's at every 90 degree bend for clean-outs. You never know when you'll need it!

Looks good to me. We can't use the black stuff here. for some reason. White PVC is all the supply houses carry

This is how I have seen it done. Leaves more room for drawers and shelves, especially cabinets with drawers in the middle.

Agree on the space but sometimes the wall can be sitting directly over a beam or floor truss/girder etc...

Very true.

Sure , it would have been best inside the wall cavity.. I would say there was some reason for him to move the drain out like he did...

if you're worried about stray nails / screws , just follow the electrical code and put a steel plate on the stud over the pipe ....

I don't see anything wrong with it, just a few things that I would have done differently. I would never have gone up through the floor like that, even if it meant framing out the wall to get more room. I also prefer using white pvc for my vent lines. There are a lot more choices out there for fittings and you can see the primer more easily. Lots of purple on a joint is a good thing!!!!

Why so many staples on the wiring?

Keeping the plumbing in the wall is important, even if as Eddie says, you need to build out the wall to do it. When time comes to install the cabinet (especially if store bought) the job will be a lot easier that way. With the drain in the floor and the vent going through the wall up under the countertop, the cabinet installation will require a lot of whittling.
