When this becomes an emergency

What a pro does

Proving there's a leak comes before finding it. The plumber closes fixtures, watches the meter, then isolates the house from the service line to establish whether the loss is inside or out on the buried run between the meter box and the wall. That distinction matters on these lots, where the service line can be long and run under a driveway or up a bank. Inside, sections get isolated and pressure tested until the loss narrows to a run, and listening equipment and moisture meters do the rest. Old galvanized supply is the frequent culprit in the prewar and midcentury houses here. It corrodes from the inside and leaks first at a threaded joint, often behind a wall in a bathroom that's been remodeled around it. Copper from later decades leaks as pinholes instead. He cuts the failed section, uses proper transition fittings if two materials meet, and pressure tests before closing anything up. Then he checks the rest of that run, because the pipe next to a failure has lived the same life.

Frequently asked questions

Turn off every fixture and appliance that uses water, including ice makers, then look at the low-flow indicator on the meter. If it's moving at all, water is leaving the system somewhere. That tells you a leak exists, though not where, and it's a useful thing to have confirmed before calling.
Yes, and it happens often enough that a plumber checks it early. Closing the valve at the house separates the two. A buried service line leak may show as a soft or greener strip in the yard, though on a slope the water can surface well away from the actual break.
Water follows framing and pipe until something stops it, then it drops. It'll travel the length of a joist bay before showing itself. That's why locating the source comes before opening anything, since cutting where the stain is usually finds dry wood.
One pinhole isn't. A pattern of them is, since the cause is generally water chemistry or pipe age acting on the entire system rather than one unlucky spot. When a plumber has repaired the third one in two years, that conversation is worth having honestly.
