As another hot, dry summer continues across North Texas, homeowners should pay attention to more than their lawns and water bills. Extended dry conditions can also affect the soil surrounding a home’s foundation and place additional stress on underground plumbing lines.
The Texas Water Development Board’s drought dashboard showed that more than half of Texas was experiencing abnormally dry conditions or worse as of August 11, 2026. The U.S. Drought Monitor also reported that dryness and drought had been expanding across much of the southern United States.
For North Texas homeowners, these conditions can increase the risk of foundation movement and hidden plumbing problems, including slab leaks.
How Dry North Texas Soil Affects Plumbing
Much of the Dallas–Fort Worth area contains expansive clay soil. This type of soil absorbs water and expands during wet periods, then contracts as it dries.
During an extended period of heat and limited rainfall, the soil around and beneath a home may shrink and pull away from the foundation. When moisture eventually returns, that soil can expand again. Repeated soil movement can place pressure on a home’s foundation and the water and sewer lines running beneath it.
Pipes beneath a concrete foundation are not designed to move freely. If the surrounding soil shifts, plumbing lines and connections may become strained. Older pipes, weakened fittings and improperly supported lines may be especially vulnerable.
A drought does not automatically mean a home will develop a slab leak. However, dry conditions and soil movement can contribute to the stress that causes an underground pipe to crack, separate or begin leaking.
Warning Signs of a Possible Slab Leak
Because slab leaks occur beneath the foundation, homeowners may not see water immediately. The first clues are often changes inside the home or on the monthly water bill.
Possible warning signs include:
- An unexplained increase in water usage
- The sound of running water when fixtures are turned off
- Warm areas on tile or other flooring
- Damp flooring, carpet or baseboards
- Cracks developing in flooring or walls
- Reduced or inconsistent water pressure
- Musty odors or signs of mold
- Water appearing around the foundation
- A water meter that moves when no water is being used
Not every one of these symptoms confirms a slab leak. A leaking toilet, irrigation problem, damaged service line or plumbing fixture can produce similar symptoms. Professional testing may be needed to determine where the water is escaping.
A Simple Water-Meter Test
Homeowners who suspect a hidden leak can perform a basic water-meter check.
First, turn off every faucet and water-using appliance in the home. Make sure toilets are not running and irrigation systems are off. Then locate the water meter and watch the leak indicator or meter reading.
If the meter continues moving while no water is intentionally being used, water may be escaping somewhere in the plumbing system.
This test can indicate that a leak may be present, but it will not identify the location. Avoid breaking flooring or opening walls until the plumbing system has been properly evaluated.
Ways Homeowners Can Reduce Soil Movement
Homeowners cannot control the weather, but they may be able to reduce dramatic moisture changes around the foundation.
Helpful practices include:
- Following the foundation-maintenance recommendations of a qualified professional
- Keeping gutters and downspouts in working condition
- Directing drainage away from the foundation
- Repairing irrigation leaks promptly
- Avoiding excessive watering in one concentrated area
- Watching for soil pulling away from the foundation
- Checking the water meter when bills increase unexpectedly
Homeowners should also follow local watering restrictions and avoid making major changes to foundation watering without professional guidance. Too much water can be just as problematic as too little when it is applied unevenly.
Why Early Leak Detection Matters
A small underground leak can waste a significant amount of water and may eventually damage flooring, walls, cabinets or the foundation area. It can also create conditions that allow mold or mildew to develop.
Early diagnosis may give homeowners more repair options. Depending on the location and condition of the damaged line, a plumber may recommend a localized repair, rerouting the affected line or replacing a larger section of deteriorated piping.
Professional leak detection may involve pressure testing, line isolation, acoustic equipment, thermal imaging or other diagnostic methods. These techniques help narrow down the source of the leak and reduce unnecessary damage to the home.
When to Contact a Licensed Plumber
Homeowners should schedule an inspection when they notice unexplained water usage, signs of moisture or recurring plumbing symptoms that cannot be traced to a visible fixture.
Total Plumbing Service Inc. has served homeowners throughout Dallas–Fort Worth since 1996. Its licensed plumbers provide professional leak detection and repair for water, sewer and gas lines, including suspected leaks beneath concrete foundations.
As North Texas moves through another period of hot and dry weather, a quick water-meter check and attention to early warning signs may help homeowners identify a hidden plumbing problem before it causes more extensive damage.
