    Speaking of Leaks...

    This one was not as difficult to find as the other thread, but I wonder what caused it.

    The lines were in a chase in the floor, the only line set in the chase.

    The install was only 3 1/2 years old.

    Any ideas?

    Leaking section pulled out of the pit.

    i would guess that the installer pulled the lineset like it was a pice of BX cable and wore the copper down, or there's a high acidity content in the air.. Had an account at a land fill once and we had to paint all the exposed copper and order everything with coated coils or it would look just like that within a year. Turned out that it was due to the ambient air quality being so poor.

    It was not worn, it was pitted and corroded only in about a 12" section. the rest of the 50' that was under the floor was fine.

    That used to happen to copper at a steel mill I used to do service at. It was common practice to use hose to pipe up split systems. We had a machine to put aluminum flare fitting on the hose. The air was so bad a brazed joint would corrode away in less than a year. I laughed when I first got there until I saw it for myself. My job was constantly repairing leaks and changing coils. Even coated coils that looked like they would never leak when they were brand new, a year later they looked like crap.

    Hmm. Never seen pitting like that. Was this in residential?

    Looks like electrolysis to me.

    Wow.. didn't realize it had been so long since I had been on here. No, this was not residential, this was in a Market, in a chase in the floor going to a set of cases. When we pulled the lineset.. we wondered who had been peeing on the linesets as they were being installed.

    I can't fix it if it won't stay broke..
