Water Leak Repair
If the meter is still moving with the whole house shut off, close the main and keep it closed until the source is located.
When this becomes an emergency
- A growing brown ring on a ceiling under a bathroom.
- A damp, musty smell in a finished basement with nothing visible.
- The meter dial creeping with every fixture in the house closed.
- Paint lifting or trim swelling along the bottom of a wall.
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.
