How to run pex in attic.
House is in colorado.
For a variety of reasons from pipe damage under a slab to home design constraints water pipes may need to be run or rerouted through a home s attic.
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 insulation below pex and r 40 above.
My plan is to run pex thru the attic below the insulation.
San antonio is a temperate climate and it rarely gets below freezing and i know pex is more resilient when is comes to freeze ups as the plastic tends to expand as needed.
When running pipe from a slab to an attic use cross linked polyethylene tubing or pex instead of copper.
Running pex in an attic.
Because there are.
I would re route it into the attic and down to each fixture.
Existing ranch has very low ceilings 7 8 so dropping any ceilings will not work.
But even if you install pex fittings in a conventional main line and branch system the connections are quicker to make than soldering copper.
Pex c is the most economical choice with a 10 foot section running 1 75 to 3 50 depending on brand and diameter.
Pex is semi flexible which allows for long continuous runs through joists and studs.
Best case imo is to use continuous runs of pex with no fittings in the attic so your plumber will have to plan the layout a bit and the pipe should be very well insulated and protected from damage so that people walking through the attic insulation can t step on it.
