Pex Water Lines In Attic

Pex is available in a variety of lengths from short 10 foot pieces for small repairs to rolls over 500 feet long which are used to install a home s entire water supply system.

Pex water lines in attic.

While pex does not ordinarily burst in the cold the water in the pipes can still freeze. Such as at night if the attic temp is 15 deg f. Insulating pex pipes offer its own unique set of challenges and considerations. It is important to insulate pex pipe in an attic particularly in cold weather areas.

What is pex plumbing. A pex supply won t corrode like copper. A pex supply is unaffected by acidic water and is therefore a better choice in these areas. That s because pex pipes basically a type of plastic are physically different from other common piping materials.

No interior walls to use either. 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. They also contract with heat cold and sometimes even water flow.

Pex is semi flexible which allows for long continuous runs through joists. There s been a lot of debate over pex for the last several years because pex has a few downsides that you might not expect. Insulation only slows the time when it will freeze after the water is not running through the pipe. They are very flexible and less prone to cracking.

Pex tubing or piping is used for water supply lines as well as radiant floor heating. Use pex pipe when running pipe from a slab to an attic use cross linked polyethylene tubing or pex instead of copper. My plan is to run pex thru the attic below the insulation. 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.

Pex type is forgiving when it freezes as far as breakage but insulating an exposed water line does little to keep it from freezing.
