I recently repaired a pipe at the back wall of my home where as l had to dig under the slab and it was reachable.
Best way to run water line in attic.
Otherwise a cold water line run a long distance through a hot attic can take several minutes to deliver cold water to a.
Insulation will help maintain water temperature levels in the pipes.
I now have a water leak that could be further under the slab and not reachable.
For better support at every two to three feet along the water line use a nylon or cable clamp to secure the line to the cabinet back or along a floor joist if applicable.
Keep the fridge water line from kinking as you complete the run.
My plan is to run pex thru the attic below the insulation.
Through this can be pulled the pex water lines.
Pull and secure the lines.
Rough in the lines.
Position the fittings and solder.
Run the lines under the floor in the basement not unheated crawl space where freezing will be much less likely.
It is never wise to run water lines in an outside wall or above an insulated ceiling in an unheated space.
Mark and drill the holes.
Maybe the proper fix for the under the slab routing of the water lines was to install 4 diameter pvc piping under through the slab that has all gradual turn corners.

If possible run it under the attic insulation for an added layer of protection.
Water line would run over the top of the 2x4 bottom truss cord and i would create a tent over pipe so there was no.
If ever a leak you can pull new lines through the pvc without digging up slab once again.
Connect the water lines.
When using modern plumbing materials such as pex tubing that is flexible this is often the best choice.
Run the water lines.
30 year or more home built on a slab and water lines are being damaged and lines are breaking.
Run the lines under the insulation in your ceiling next to the heated drywall.
The pipes should slope gently away from the existing vent pipe so water can travel downward.
These spaces are already designed to allow for long unbroken runs for pipes.
Existing ranch has very low ceilings 7 8 so dropping any ceilings will not work.
Do the rough stub outs.
It is also important to run the pipe as low in the attic as possible to provide heat from the ceiling below.
Your inspector may want you to include a tee fitting to be used for testing.
