Sand in water supply cause pinholes in pipe

Chandler,

I noticed on another thread you made the statement that a pinhole in a copper pipe could have been caused by sand in the water supply. I am curious how this can happen?

Thanks...Randy

Sand, for some reason doesn't flush completely when water runs through the pipes. It tends to swirl around and virtually wears out the inside of the pipe. I have pulled copper with sand damage and it is so thin, you can crush it with your hands. Once it gets that thin, pinholes develop. You can repair the first pinhole, but in a couple of days another will show up, so sometimes replacing an entire length is the only solution. And, if your code allows, use cpvc.
