  • I have read that PEX pipe cannot be in direct or in indirect sunlight. I am planning on re-plumbing my home with PEX pipe but it occurred to me that the pipe coming out of the floor to hook up top the toilet will be in indirect sunlight.
    So how would a plumber normally deal with this? Would you paint it, cover it with split tube insulation or what?
  • sorry about the typing error. Where I said "hook up top the toilet" should say "hook up to the toilet."
    Also since the pipe will be partially visible I would like it to look O.K. and not look like I'm just trying to cover something up.
  • You read correctly. PEX can not be exposed to sunlight, and doing so may void your warranty.

    They make a chrome tube and valve kit that covers the PEX coming thru the floor. I always come thru the floor with copper and use a PEX by copper adapter so that the PEX is under the floor. This method also allows for the use of regular supply valves.
