Re-plumbing slab pipes with PEX in attic
I have a ranch house built on a slab. Recently I've detected what I think is a leaking water pipe under the slab. This has been confirmed by a plumber. I shudder at the thought of cutting my slab to fix a leak, only to find there is another leak someplace else. My questions are these:
Is there a safe and recommended way for me to re-plumb my house using PEX running across attic and down interior walls?
How do I best insulate the PEX? Can I use heater tape on PEX?
Can the PEX be placed inside of a containment system (like a sewer pipe) that would direct water away from the house in the event that break should occur?
