2x4 Structural integrity


I'm new today to the website, so please overlook any mistakes i make. i have a house under construction, it's under roof and the plubming work has started and soon the electrical. On an interior non-load bearing wall, the plumber drilled holes through the wall studs to run a drain pvc to the main drain line for the bathroom. I guess the holes are about 1 3/4 inch and are off center. Therefore the outer edge of the hole is very close to the side of the 2x4 and in one stud, the hole broke the side of the 2x4. After running the pvc he nailed a metal plate on the 2x4. I asked the plumber if the hole would weaken the structural integrity of the 2x4's, he said the plate would reinforce the strength and therefore no loss. I thought the plate would be to protect the pvc from dry wall nails. Finally my question - does the plate help or do i need to request the work be re-done. Thank you.

2x4 Structural integrity


the plate does not give any structural integrity to the stud..

but with it being a interior non-load bearing wall there is not alot to be worried about, its only holding up the drywall..

This is what's I call a wet wall.
It would have been better to have used a 2 X 6 wall in that area, but what's done is done.
I believe the maximum size hole was suppost to be no more then 1/3rd the size of the stud.
He should have at least used a nail plate like this to strenthen the stud.

He really should have drilled in the middle of the stud. If you are really concerned, you could add 1 x 3 pine to the side of the studs on the wall in question on the flat, therefore making a T. This should add enough strength and give you a little more depth. You have to consider your toilet flange though.

What about the drain lines? Joe is right in that the plumbed wall should be at least 2 x 6 (5.5")

Thank you cbzdel, joecation and jagans! Your reply will cause me a little less stress. I thought if it was an interior wall the holes in the 2x4's shouldn't be a problem. However with the nail plate or a 1x3 as reinforcement it won't be a problem.

This is a great website - your advice is vaulabe. I can only offer help if you have a problem with dehydrators(jerky) or outdoor smokers (see Klose smokers).

What your plumber did is industry standard these days. If it's a non-bearing wall- you need not be concerned.
Nail plates are required when a pipe is within 1.25"(I think) of the edge. It's not uncommon to use 50 plates in one house.

That wall should have been 2x6, not 2x4. Even the outside perimeter walls should be 2x6 for better insulation of the envelope.

by code no wires or pipes are allowed to be within 1 1/4 of the edge of a stud. i wouldnt risk it with the plate the stud will still be flimsy.. either replace the stud or fur teh wall out to a 2x6 wall
