Soil under Devine
Devine is a small Medina County town southwest of San Antonio with older homes and rural lots.
Slabs in Devine are constructed on clay that changes volume with moisture, so every home moves slightly through the year. Lines under the slab feel that movement as repeated modest stresses at bends, tees and footing crossings. Over plenty of years the strain can wear a pipe.

Pipe under Devine slabs
In Devine, the older houses may have plumbing from a number of eras, with galvanized steel, copper and plastic joined by transition fittings.
In Devine, galvanized steel corrodes from the inside, which reduces flow and then leaks at threads. Copper and plastic fail in varied ways. Earlier leaks help a crew read the problem, so mention any you know of.
Floor work and drying are separate trades in Devine, done by flooring contractors and restoration companies. This site does neither.
Signs in a Devine house
The usual first signs of a Devine slab leak are a warm spot, a higher bill, a hiss at night or a water heater that keeps running. Most mid-century houses in Medina County can be tested without moving furniture far.
A hiss or trickle that stops only when the main is closed may point to a leak. Note which room it is loudest in. A technician confirms the cause, and no floor is opened until the leak is located.

What is different about Devine
Older neighborhoods here include raised homes, with additions on concrete that may have slab leaks.
On larger lots the line from the meter to the home can be long. A leak there does not involve the slab and is most commonly fixed by digging in the yard.
A local crew describes what happens next.
Locating the leak
A technician starts by isolating the hot and cold sides, then pressure tests the suspect line and watches a gauge. Acoustic listening and thermal imaging follow, and the leak technician describes what was found and how sure it is.

Questions we hear from Devine
Options include spot repair, rerouting, pipe lining and repiping, and a technician explains which fits your Devine home and why. The line is answered 24 hours a day for Devine callers too.
A leak is one possible reason. Sprinklers and toilets that keep running are other causes, which the meter check helps rule out. Watch the usage figure, since that is where a hidden leak tends to show up first. For older copper-plumbed homes on expansive clay, this is one of the first things a crew asks about.
Make sure nothing in the house is using water, then watch the meter dial. Movement on the meter tells you water is leaving the property. Because of expansive clay, crews in Devine test the full line rather than one spot.
Yes. Irrigation and outdoor taps can move the Devine meter like a leak, so a technician rules them out first. Mention that the home is on shifting clay soil when you call from Devine.
Not always. Sun through a window or a nearby vent can warm a Devine floor just as easily. A warm patch that holds in shade, with the heat off, and runs in a line across the floor can point to a hot-water leak. Medina County crews start with the simplest test and work toward the slab.
They can. Early on, a pressure test checks the line from the meter to the Devine house. A crew in Devine will ask what you have already checked.
No. In Devine, isolation, pressure tests, acoustic listening and thermal imaging narrow the search before anything is opened, though the result is not always one exact point. In Medina County, crews plan the visit around what you describe on the call.
Only the meter check. Do not cut into a Devine slab, since that can cause damage and still miss the leak. Call and a crew will locate it first. Phones are answered around the clock for Medina County calls.
No. A leak in Devine is a plumbing matter first. For the foundation itself, talk to a foundation contractor, as this site does not assess it. The more you describe on the call, the better a Devine crew can plan its equipment.
