What Mansfield homes sit on
Mansfield sits at the corners of Tarrant, Johnson and Ellis counties, on clay that moves with moisture. The historic center has homes from the early 1900s, some raised on piers. The 1970s and 1980s brought slab neighborhoods around it. Since the 1990s the city has grown quickly to the south and east, in subdivisions on larger lots.
That sequence matters. A 1980s house may have copper under the slab and may be of an age where polybutylene was in use. A home built since about 2000 almost certainly has PEX. A technician verifies what a given home has.

Start with the meter
The meter check separates a leak from other causes and takes minutes. Turn off every tap, appliance and irrigation zone, next monitor the leak indicator or low-flow dial for a few minutes. Movement indicates water is leaving the property. It does not say where. See water meter leak check.
Describe what you have already turned off.
Long yard lines on larger lots
On a big lot, the line from the meter to the house can be long enough to leak without any sign inside. A technician checks it early, since a pressure test between the meter and the home reveals quickly if the leak is outside. Closing the home valve and watching the meter does a rough version: if it still moves, the leak is on the yard side.
Irrigation and pool lines produce the same meter reading. Those are ruled out before anyone looks at the slab.
Raised homes close to the square
A raised house has a crawlspace in place of a slab, so a supply leak is under the floor but reachable from below. Additions on concrete are the part that can have a slab leak. Tell the technician which parts of the home are raised. See aging home slab leaks.
A local crew describes what happens next.
PEX and the one-point leak
In newer subdivisions a leak is more frequently a single fitting or a damaged spot than general wear. The signs are the same. See PEX slab leaks. If the home is under a builder warranty, check what it covers and call the builder as well.

How technicians pinpoint it
The technician isolates hot and cold lines, pressure tests the suspect line and listens along the floor with acoustic equipment. Thermal imaging may show a warm path under tile or wood. These measures pin down the position before any opening is made, though they do not always give an exact point.

What a visit in Mansfield involves
Calls from Mansfield are answered by a person at any hour. The call goes faster with your ZIP, a short description of the sign, and whether water is visible. The first thing the line asks a Mansfield caller is the ZIP code, so the call reaches a crew that already works in Tarrant County.
A recent water bill is worth pulling out. A sudden rise on a Mansfield account, with no change in use, gives the crew a rough sense of how fast water is escaping. Keep your meter reading nearby, plus a note of any rooms that feel warm or damp. In a newer PEX-plumbed Mansfield house, the location of the water heater is also useful.
Acoustic equipment picks up the sound of water escaping under pressure. A quiet house makes that listening easier, so a Mansfield crew may ask you to pause appliances. Testing a newer PEX-plumbed home usually means isolating hot and cold lines separately. That tells the crew which side is losing water before anyone looks for the spot.
A locating visit in Mansfield often takes a few hours, depending on the size of the house and how many lines run under it. Crews that also cover Crowley and Grand Prairie plan their routes around urgent calls first, so describe the situation plainly.
If the hot side is leaking, closing the cold supply valve on the water heater can slow the loss until a Tarrant County crew arrives.
