Pin hole in copper pipe.

Dan S. MacAbre · 2018-10-01T11:25:09+00:00

I spent a fair few hours over the weekend tracing and fixing a small, but annoying, leak (cold mains water supply to the bathroom upstairs via the ceiling void). The cause turned out to be a very small hole, out of which the water spurted in a tiny jet every few seconds. Now I'm wondering about the rest of the pipework, which is about 30 years old. Is this just a bit of bad pipe that has taken that long for a hole to break through (we have soft water), or is it likely to start happening elsewhere because this is what happens to 30 year-old copper pipes with soft water?

Same here - did lots of work on this house 5 years either side of that. Lots of new plumbing. None of which has pin holed.

Likewise in the electrical industry, the alloy would turn to dust and high resistance with just a small amount of moisture.
