Green Spots on a Copper Pipe in Nampa? A Pinhole Leak Weeps Before It Bursts — and One Means Checking the Rest of the Line

A pinhole leak in a copper pipe in Nampa shows as green or blue staining, damp drywall or a small drip, and it starts as a slow weep rather than a burst — often where hard water has corroded the inside of the line over time. The first signs are green or blue staining on the pipe, damp drywall, or a small drip at a joint, and pinholes often open where water sits or where the line changes direction. A stain that is damp to the touch, or a meter that moves with everything off, turns a stain into a leak worth finding. Finding a pinhole starts with the meter test, then a pressure test on the suspected section, which proves whether that section is losing water; listening and thermal checks then narrow the failed joint, so only the narrowed area is opened, not the whole wall. Because the same water runs through the entire line, one pinhole is a reason to check the rest of it: a pressure test on the section shows whether more of the line is losing water, before the wall is closed again. A pinhole starts as a slow weep, but it runs around the clock, and a small continuous flow adds up across a billing period even though nothing looks wrong — compare usage in gallons across two or three bills, then run the meter test.
