This thread is helping a lot
Because I'll be running a new PEX line from the meter in to my house, the question is how do you protect/seal it where it goes through the foundation? The old galvanized line comes up through the slab so I won't be able to reuse that way in.
I've read that PEX needs to be "sleeved", either with rigid pipe or with insulation wrap when it goes through a foundation but need some more details.
If I'm running 1" PEX then I *think* I need to go up 2 pipe sizes for the sleeve (2"? Or 1-1/2"?); extend the sleeve at least 12" beyond the outside wall; spray foam the gap inside the sleeve; and parge the inside surface of the wall (i.e. covering the exposed spray foam) to prevent ants/termites from burrowing through the foam.
Does this sound right? Or is there a better way that you'd recommend?
