Leaving Town This Summer? How To Keep a Water Leak From Ruining Your DFW Home While You're Gone
A supply line under the upstairs bathroom sink lets go on the second day of your trip. In an occupied house, you'd hear it, see it, shut it off in minutes. In an empty one, it runs. By the time you're back from vacation, water has been flowing for days — through the ceiling, down the walls, into the flooring on two levels. The leak itself was ordinary. The week of unattended running is what turned it into a five-figure problem.
Why an empty house is the dangerous part
The leaks that ruin homes over the summer aren't usually exotic. They're the same washing-machine hoses, water-heater connections, toilet supply lines, and refrigerator water lines that fail in occupied homes all the time. The difference is time. A leak someone catches in ten minutes makes a mess; the identical leak running unwatched for five days while you're at the beach can destroy floors, cabinets, and ceilings across the house — and seed mold throughout, given a DFW summer's heat and humidity working in your absence.
Vacancy doesn't cause the leak. It removes the one thing that normally stops a leak from becoming a disaster: a person who notices.
Before you leave: the high-impact moves
A few minutes of prep does most of the protecting.
- Shut off the main water supply for any trip longer than a long weekend. This is the big one — with the main closed, the worst a failed line can do is drain the water already in the pipes. Open a low faucet afterward to release pressure, and set the water heater to vacation mode.
- If you'd rather not kill the whole house, at least shut the local valves to the washing machine, the icemaker, and any toilet or sink you can. Washing-machine hoses and icemaker lines are among the most common culprits.
- Replace anything past its prime now. Swap rubber washing-machine hoses for braided stainless steel, and look hard at any supply line that's brittle, corroded, or older than you can remember. Don't leave a known weak link to fail while you're gone.
- Leave the AC on, set around 80–82°F. It keeps humidity down so the house — and anything that might get wet — isn't sitting in sauna conditions.
- Clear roof drainage if storms are likely. Summer in DFW means pop-up thunderstorms; clogged gutters and downspouts send water against the foundation and up under the roofline.
Set up a set of eyes
Technology and a trusted human together close the gap that vacancy opens:
- Put a few water-leak sensors under sinks, behind the washer, and by the water heater. The inexpensive Wi-Fi kind text your phone the moment they sense water — sometimes early enough to act from the road.
- Consider an automatic shut-off valve if you travel often. It detects an abnormal flow and closes the main on its own, no human required.
- Ask a neighbor, friend, or house-sitter to physically walk through every few days. A sensor catches the leak it's sitting next to; a person catches the slow ceiling stain, the musty smell, the drip the sensor missed. Many insurance policies actually expect these check-ins for longer vacancies.
What not to do
- Don't turn the AC completely off to save on the bill. A sealed-up Texas house with no cooling becomes hot and humid fast, which stresses materials and primes any moisture for mold.
- Don't skip reading your policy. Extended-vacancy clauses are easy to overlook and can affect a claim — know what yours asks of you before a long trip, not after.
- Don't rely on a single safeguard. A sensor with a dead battery or a house-sitter who gets busy is one point of failure. Layer the shut-off, the sensors, and a human so no single miss leaves the house exposed.
A note for DFW homeowners
Two things make summer travel riskier here. Our two-story homes mean an upstairs leak rides the framing down and can damage both floors before anyone's the wiser. And our clay soil keeps foundations — and the plumbing in them — moving through the dry, hot months, so summer is also prime time for a slab leak to surface. If you're heading out for an extended stretch, shutting off the main isn't just a washing-machine-hose precaution; it covers the supply-line failures that North Texas summers are especially good at producing.
If you come home to water
If you walk back into standing water, a stained ceiling, or that unmistakable musty smell, the priority is fast, measured drying — and after a leak that ran for days, there's almost always more hidden moisture than the visible damage suggests. A restoration crew maps the full footprint with moisture meters and thermal imaging, dries walls, flooring, and framing to a measured standard, and addresses the mold that days of unattended water in summer heat has likely already started. The sooner that happens, the more of the house is saved.
Bottom line: the leak that ruins a home over summer vacation is usually an ordinary one that simply ran too long. Shut off the main, set the AC to keep humidity down, add leak sensors, and have someone check in — layered together, those steps mean an empty house isn't a defenseless one.

Frequently asked questions
Should I really shut off the main water valve before a vacation?
For trips of more than a few days, yes — it's the single most effective thing you can do. With the main off, even a failed supply line or a burst washing-machine hose can't flood the house. Just remember to drain a couple of faucets afterward to relieve pressure, and turn the water heater to vacation mode so it isn't heating an empty tank.
Will my insurance still cover water damage if the house was empty?
Usually yes for sudden, accidental damage like a burst pipe, but many policies have conditions for extended vacancy — some require the water shut off or the home checked periodically past a certain number of days. Read your policy before a long trip, and line up someone to check the house so a small leak doesn't run unnoticed for weeks.
How high should I set the thermostat if I'm gone during a Texas summer?
Don't switch the AC off entirely. Set it around 80–82°F so the system still pulls humidity out of the air. A closed-up DFW house with no cooling can climb into the 90s with high humidity, which stresses materials and gives any moisture a head start toward mold. A smart thermostat lets you watch it from the road.
