There are several water supply lines made of CPVC that do not appear to be secured behind the wall at the point of exit (to supply water to a fixture). Are there any building codes regarding securing the water supply behind the wall? I'm in Virginia, USA.

    Does the faucet or outlet have provisions to mount to the wall? Or could the pipe be strapped to the wall? Oct 1 '19 at 21:00
  • Are you asking because you feel that a contractor is doing something wrong or because you wish to make it more robust for peace of mind? If the latter then go ahead and secure it.

  • The fixture is secured I usually will strap if a long run to reduce water hammer.

  • The wall is already closed, so it would not be easy or quick to secure. CPVC pipe can be pulled through the opening in the drywall and pushed back again. I don't see any leaks, but I thought maybe the elbow should be secured to bracing or a stud. In the past, I've installed a pex -elbow-nipple assembly, and the elbow has two eyelets to secure to the wall.
