The ground beneath Marion homes
Marion is a very modest Guadalupe County town northeast of San Antonio with aging homes and rural lots.
The soil under Marion is clay that swells when it takes on water and shrinks and cracks when it dries. A slab rides that movement a little at a time. Lines under the slab feel that movement as repeated modest stresses at bends, tees and footing crossings. Over plenty of years the stress can wear a pipe.

What Marion homes are plumbed with
A home in the aging part of Marion may not have a slab under the whole floor, so the first question is which parts are raised and which are on concrete. Ask a crew in Marion what this means for a mixed-age house like yours.
Each joint between materials is a place a leak can begin. A leak technician maps what is in the Marion home as part of the search. What you share on the call tells a Marion crew which equipment to bring.
Rerouting through an attic or wall can avoid opening a Marion floor that would be hard to match. The 24-hour line takes calls from Marion as well.
Clues worth acting on
Most slab leaks are first noticed in one of a few ways: a warm patch on the Marion floor, a water bill that rises with no change in use, or the sound of running water when everything is off. Mention any earlier leak in the Marion home when you call.
A water heater that runs more than usual may be replacing hot water that is leaking away. The cause is confirmed by a technician, and finding the leak always comes before opening a floor.

Local factors in Marion
Long yard lines are a common source on larger lots. A technician checks them early with a pressure test between the meter and the Marion house. Check for soggy soil or a strip of greener grass along the line, and listen near the meter. This site does not repair pools or irrigation. Before calling, Marion homeowners can do this in a few minutes.

Tracking down the leak
In Marion, the first step is isolation: closing valves to learn which line is losing water, next pressure testing that line. Acoustic listening and thermal imaging follow, and the technician explains what was found and how sure it is.

Marion homeowner questions
They can. The line from the meter to the Marion house is checked early with a pressure test. Phones are answered around the clock for Guadalupe County calls.
In Marion, floors go to a flooring contractor and drying goes to a restoration company. This site connects you with leak crews and does not do either. Most mixed-era houses in Guadalupe County can be tested without moving furniture far.
No. Crews in Marion use line isolation, pressure testing, listening gear and thermal imaging to narrow the spot first, and the result may be an area rather than a point. A local crew covering Guadalupe County can walk you through the next step.
A leak is one possible reason. Irrigation zones and a toilet that keeps refilling are other suspects, and checking the Marion meter helps tell them apart. Usage on the bill often climbs before a hidden leak shows any other sign. Because of clay that shrinks and swells, crews in Marion test the full line rather than one spot.
Over many years, clay that swells and shrinks puts gradual strain on the lines beneath a Marion slab. A technician has to locate a leak to say what caused it. In Marion, a dry summer followed by steady rain makes the swing in the soil more pronounced.
Only the meter check. Leave the Marion slab intact until testing points to a spot, since guessing can cause damage. Call and a crew will locate it first. A Guadalupe County crew can tell you how long the visit is likely to take.
A meter check and a leak technician’s assessment before closing can show if water is escaping.
In Marion, drain leaks do not follow the water supply, can leave a damp patch or a smell without a bill increase, and are found by isolating and testing the drain system. When you call from Marion, say that the home sits on clay that shrinks and swells.
A technician may present spot repair, rerouting, pipe lining or repiping, and explains what steers the choice for your Marion home. For varied-age homes on clay that shrinks and swells, this is one of the first things a crew asks about.
