Water heaters, washing machine hoses, dishwashers, and refrigerator ice-maker lines cause some of the quietest water damage there is. The leak often starts behind an appliance where nobody’s looking.
Where the quiet floods start
A washing machine supply hose can fail mid-cycle and dump gallons behind the machine before anyone notices. A dishwasher’s water line can weep for weeks under the cabinet without a visible sign until the cabinet floor swells. A refrigerator’s ice-maker line is thin plastic tubing that can crack quietly for months. And in a lot of Katy homes, the water heater sits up in the attic rather than a closet. That’s common in slab-on-grade construction, where there’s no other good place to put it. When an attic tank fails, gravity does the rest. You get ceiling and wall damage on the floor below, rather than a wet spot where the tank stood.
Shut off at the appliance, not just the meter
Every major appliance that uses water has its own shutoff, usually a small valve on the supply line right behind or under it. Learn where those valves are before you need them. In an emergency, reaching the street meter or the whole-house shutoff takes longer, and it cuts water to the entire house. Shut off at the appliance first if you can find the valve quickly; go to the main only if you can’t.
Burst hose vs slow drip: it changes the insurance answer
A supply hose that lets go all at once is a sudden failure. Insurers generally treat that differently than water that seeped under the same appliance for weeks before anyone noticed. Both happen under the exact same washer or dishwasher. That’s part of what makes it confusing. The full explanation of how insurers draw that line lives in the homeowners insurance and water damage guide.
The hidden damage behind and under
What you can see is rarely the whole story. Water that leaked behind an appliance often travels along the subfloor before it shows up anywhere visible. It soaks into particleboard cabinet bottoms and subflooring that hold moisture long after the surface looks dry. That hidden moisture is what feeds mold if it isn’t found and dried. It’s one more reason a quick wipe-up isn’t a real fix.
Plumber’s job or restoration’s job
Fixing or replacing the appliance and its connections is plumbing work. Drying out the walls, cabinets, and flooring around it, and repairing what got damaged, is restoration work. Most appliance leaks need both. It often makes sense to get drying started while the appliance repair gets scheduled separately. For what that repair work looks like once things are dry, water damage repair goes over what actually gets fixed versus replaced.
If a freeze rather than an appliance is behind your leak, burst pipe cleanup goes over that situation specifically.
Appliances fail on their own schedule, never on yours. Knowing where your shutoffs are before you need them is the cheapest insurance you’ll ever have. And when one lets go anyway, call us and we’ll get a cleanup crew moving.
Common questions
My water heater burst. What do I do in the first 10 minutes?
Shut off the water supply to the tank first, then cut power to it at the breaker if it's electric or the gas valve if it's gas-fired. Move anything you can out of the water's path, then start moving standing water away from walls and cabinets if it's safe to do.
Is appliance leak damage covered by insurance?
It depends on the policy and how the leak happened. Insurers often treat a sudden failure and a slow weeks-long drip differently. Check your policy language directly rather than assuming either way.
Do I need to replace the flooring under the appliance, or can it be repaired?
It depends on the material and how long it was wet. Tile and sealed vinyl sometimes just need drying underneath. Wood, laminate, and carpet padding that soaked for more than a few hours usually need to come out, especially if the subfloor underneath got wet too.
