When this becomes an emergency

What a pro does

Locating comes before repairing, and a good plumber spends most of the visit on the first part. The meter test is the opening move. Everything off, watch the dial, and if it moves the house is losing water under pressure somewhere. If it doesn't, the leak only happens when something drains, which points at waste piping instead. From there the plumber narrows: isolating sections of the system, metering moisture through the drywall, and reading temperature differences to find the wet path without opening the whole wall. There's a regional habit worth mentioning. Houses here are built tight against long winters, with heavy insulation and vapor barriers, and that means a small leak can stay damp inside a wall for a long time without ever drying or showing itself. By the time a stain appears the wet area is usually larger than the mark suggests. Once the source is found, the repair matches the existing pipe, the joint gets pressure tested, and the surrounding material gets checked, since wet insulation in an exterior wall is also a freezing problem waiting for January.

Frequently asked questions

Shut off every water using fixture and appliance, including any icemaker or humidifier, then read the meter twice an hour apart. Any movement means water is going somewhere it shouldn't.
Water travels along framing until something interrupts it. It'll run the length of a joist and come through the ceiling wherever the drywall seam is weakest, which is rarely under the actual break.
It does. Wet insulation loses most of its value, so the cavity gets colder, and a cold cavity with a supply line in it is the setup for a freeze. A summer leak in the same wall is a smaller problem than a January one.
The drywall has to come off over the failure itself, though good locating keeps that to a small patch. Trying to avoid opening anything is how people end up cutting four holes instead of one.
