  • Pex & uv

    You're supposed to protect ALL PEX from UV.

    Ever think about PEX stubouts on say-a water closet? The riser?

    Wouldn't insurance deny any claim?

    Unless you have black lights in the home you should be okay. Normal household lights do not put of UV. That said I prefer copper stub outs to PEX terminations.

      Can UV get in through windows? What range of UV would they block? Would they block some UV but not the damaging UV to PEX? Pretty ignorant to windows UV blocking abilities.

      Just thinking.

        I suppose if you had direct sunlight (not ambient) it could creat a problem.

          Just picked up a new Wirsbo book. They offer covers to completely cover the finished stubout of a w/c.

          Wonder if it's just a profitable accessory or a necessity. I'll stay on the search.

            I checked with Uponor today and was informed that their pipe covers for W/C stubouts are NOT required as part of a warranted installation.

            Just cosmetic. Hope this helps.

                It depends on the windows. A low-e (and/or argon?) window will dramatically reduce UV. I have triple glaze windows with argon and I have used a UV meter to see what comes through. With the sun shining directly through the windows my UV meter measures 1. If I open the window it can measure anywhere from 6 - 10, depending on the time of day (essentially angle of the sun through the atmosphere).

                My velux skylights with low-e claim to reduce UV by something like 60 percent.
