Lines that supply water to the fixtures run above grade through stud walls.
How to run water feed through attic.
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.
These lines are narrower and made from copper or polyvinyl chloride pvc.
Then you can run a subpanel feeder through the attic to your existing main panel.
When running pipes from a slab to an attic use an inside wall.
Running pex in an attic.
Once the builder constructs the rough frame of the house the plumber installs the water supply lines.
Which ever way i go i know there will be alot of lines running parallel through the attic.
No interior walls to use either.
If ever a leak you can pull new lines through the pvc without digging up slab once again.
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 needed plan for the water line to run through cabinets above storage and behind drawers to prevent damage to the line.
When the pex is run throug the attic does it matter if it is run along the floor or if it is run about 4 feet above the floor along the verticle truss supports.
Existing ranch has very low ceilings 7 8 so dropping any ceilings will not work.
This could be located at the location of the new service drop as ray suggested.
My plan is to run pex thru the attic below the insulation.
Because there are.
If no boards or beams run horizontally between the wall studs the pipes can often be fed through the walls up to the attic.
Through this can be pulled the pex water lines.
Locate this connection preferably from a vertical water supply pipe then map the shortest path from the supply line to the rear of the refrigerator or where you plan to place the refrigerator.
Btw my existing pb pipe is under the slab.
Need to get a hot water line from one end of the house to the other in a ranch with a concrete slab.
