Client called us out today due to a leak in the main floor bathroom ceiling that has caused a good bit of water damage to the home. The water has also traveled to the laundry room next to it and had started puddling. Home has copper water pipes that are about 40+ yrs old. We cut out sections of the Sheetrock ceiling to expose the leaking copper pipe above. It was the cold side that has 5 separate locations that were corroded and leaking in about a 6-8’ section of pipe. We removed that section of copper and repaired with new 3/4” pex a water pipe and findings. Turned water back on and tested. No visible leaks at this time. Checked water pressure and it was perfect at 55 psi, safe range is 50-79 psi. It seems the builder of home years ago used a bent over nail to secure the copper pipe to the wood, which would more than likely be the cause of this oxidation and leaks on that section of pipe. Advised client to be highly vigilant with paying attention for leaks, as I think this is only the
