Meter and pressure tests
With every fixture off, a moving meter dial confirms that water is escaping somewhere. Pressure tests on separate parts of the system then narrow it down to the yard line, the hot side or the cold side.
Your water bill jumps with no change in habits, you hear water moving when nothing is turned on, a floor tile feels warm or a brown ring widens on the ceiling. Any of these can be a hidden leak, and finding it first means opening only one spot.
Below are the ways a leak is found, who owns which part of the water line, and Garland’s permit for repairs under a slab.

Moisture meters and thermal cameras show where water is spreading behind drywall, so the opening is made at the source instead of across a whole wall.
A pipe running under a concrete slab can leak for a long time before it shows. Listening equipment and thermal imaging pinpoint the spot, and the repair is made through the slab or by rerouting the line.
A soggy patch in the lawn or a sinking spot near the meter box can mean the buried line from the meter to the house is leaking underground.
At the meter, ownership of the water line changes hands. On the street side the City of Garland owns it from the water main up to the water meter, and on the house side the line into the building belongs to the property owner.
Garland has a separate Under-Slab Repairs permit for pipes beneath a slab. If you own the home, live in it and have it homesteaded with the Dallas Central Appraisal District, you may pull the permit yourself with a Homeowner’s Affidavit and do the repair. In any other case, you must hire a state-licensed master plumber registered with the City of Garland to take out the permit.
A rental home is treated differently: only a state-licensed master plumber registered with the city may do the repairs there. Garland’s inspectors accept photographs of under-slab repairs, sent by email in PDF format.
Leaks that return again and again in tired pipe point toward repiping. A pipe that bursts without warning is an emergency call. For everything else, visit our homepage.
