How to run pex in attic.

House is in colorado. Running pex in an attic. 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. Because there are.

If you use a manifold and home run system it s like running a garden hose to each fixture super fast and easy. Pex c is the most economical choice with a 10 foot section running 1 75 to 3 50 depending on brand and diameter. I looked in the attic and noticed that all of the plumbing that once was in the slab had been replaced by pex and was now in the attic. Pex is semi flexible which allows for long continuous runs through joists and studs.

No interior walls to use either. My plan is to run pex thru the attic below the insulation. 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. Existing ranch has very low ceilings 7 8 so dropping any ceilings will not work.

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. I would re route it into the attic and down to each fixture.
