    Default pipes around water heater develop pinhole leaks fairly frequently

    Hi,

    I live in Santa Fe, New Mexico (in case the climate or the hardness of the water matters for this question). I have 9-year old house. A few years ago one of the pipes by the water heater developed a pinhole leak. A couple of years later another one developed. Four months ago another leak, two months another one and, now, I have a brand new tiny leak. Every time I have a leak I bring in the plumber and he replaces the piece of bad pipe.

    Is there a long-term solution to this problem?

    Tomorrow afternoon the plumber is coming in again. I've asked him for his thoughts on how to fix this problem for good. He says he has some thoughts he's going to share. I would appreciate the input of members of this forum as well. What are my options? Replace all the piping with something other than copper that isn't going to leak, if such a thing exists? Install anodes in the water heater?

    I'm not a DIY kind of guy but I'd like to have an intelligent conversation with the plumber.

    Thanks very much.

    Are these on the hot outlet or cold inlet side of the water heater. There is a theory that bits of metal from the sacrificial anode deposit in the copper pipe and react with the copper causing the pinhole.

    I'm not positive but I believe most have been on the hot side.

    Next Q: Are the pinholes on vertical or horizontal runs?

    Are you on city water or on a well? Do you have a softener? Doing a chemical water test would be a first step in figuring out the problem. Here is a good link to learning what causes corrosion in copper pipes.

    I've not paid attention. They've always been near an elbow but I couldn't tell you whether on vertical or horizontal runs.

    City water. No softener.

    Will read the two docs you linked to. Thank you.
