  • copper leaks

    About 6 years ago I replaced all the copper pipe on my 2nd floor because of 4 pinhole leaks. it was all on 3/4 so I figured it was a defective stick. no hot water return line. heck it may have been on the cold side anyway?

    I just fixed a pinhole on the 1st floor, 1/2 copper going to a toilet. copper holds up great in my area. I wounder what could be the trouble.

    Anyhow a repipe in the basement will be a breeze

    Re: copper leaks

    since there was no return line, velocity erosion is not the issue.

    i would look to see if there is flux still slobbered on the outside of the pipe and still inside the joints.

    how is your water quality in general. is it city water or private well?

    talk with your neighbors and see if they've had pin holes too.

    was the original install part of a tract home or was it a custom home with 1 of a kind installation?

    of course you could always take the sample pipe and pinhole sections to a metallurgist and see what the microscope says.

    the drop of pex i worked with many years ago, makes me want to use pex for my own home in the future.

    at least your bidet didn't spring a leak

          this leak could be flux. it was close to a fitting. I know the company very well that plumbed the place. they were flat out fast at the expence of wipeing excess flux off. that was the place I started plumbing at a few years after I built the house. I learned some bad practices.

          pex has gone in on the 2nd already so pex will go in the basement. hopefully pex will stand the test of time.

              Re: copper leaks

              i replace ALOT of copper around here due to pinholing and FITTINGS IN LIKE A THIRD OF THE WAY (HACKS PISS ME OFF!!!!).... typically bad installation IE; flux not getting wiped off, thin wall M just not with standing the test of time. I personally love PEX for the wall thickness and how much it resist corrusion from our HORRIBLE water in huntington beach and surrounding areas.

                    Pex over time might be absolute junk, but I have seen enough of it to know mice or rats eating through it isn't a problem. we have miles of it run in our area. could it happen yep.

                      Plumbus can you give a link to the Copper Development Association. We have one here and it would be interesting to see more. We also have issues with copper corrosion. Rick nailed the biggest culprit, water quality. Again I am not an expert but rather an active interested plumber.

                            but remember that in australia, their mice are the size of our rats. and their rats are the size of our possums

                            i've seen abs pipe eaten by critters. heck even our garbage cans get chewed on.

                              We are seeing numerous rodent caused pex leaks, especially where the pex is contained in walls.
