Running Copper Pipe Through Bottom Plate?


I am starting on a 2-story addition to my house. I already have my 3/4" water line sticking out from the existing house through a hole I drilled in the bottom plate. I have a few more lines to run and I need to drill through other plates to get the water where I want.

I'm assuming this is ok? I sure hope so....the other options are not pretty.

Here is a pic of the main line coming out....I still need to run the hot water line as well as gas.

looks neat i would put a shut off on any and all line coming from the house ...gas and or water with in that crawl space opening easy access. cut pieces of pvc slid down the pipes to where it comes thru the wall if concreted in to keep the copper and concrete from reacting into your retirerment years...just an opinion

You can't see it very well in this photo....but the pipe where it comes out of the plate does have a ball valve on it....that will allow me to work on the plumbing in the new addition without shutting off all the water to the front part of the house.

I need to take a pic of the pipe coming through the bottom plate so you see exactly what i'm talking about.

nothing wrong with running pipes through wood like that, but I use an 1 3/8" bit for copper lines up to 1". This size of hole will accept what is called "pound in" pipe isolators. They protect the pipe from rubbing against the wood.
