Plumbing in Texas splits into three disasters, and they are not interchangeable. Clay soils shift and stress lines under a slab until a leak shows up as a hot spot in the floor. A short freeze, especially where winter usually stays mild, bursts attic lines, hose bibs, and garage piping nobody protected. Heavy rain pushes water backward through floor drains and older sewer laterals. Name which of the three you have.
A slab leak and a freeze break leave different evidence. The slab leak is often quiet: a warm stripe in the flooring, the sound of water when every fixture is off, or a damp carpet that never quite dries. The freeze break is loud and timed to the thaw. Ceilings stain under attic runs, a garage heater lets go at a fitting, or an exterior bib splits down the brick. Do not close the ceiling until the failed pipe has been seen.
Older houses add material problems that the weather then exploits. Galvanized supply lines close down with corrosion. Cast-iron drains scale and crack, then surcharge when a tropical downpour fills the city line. Hard water in limestone regions packs water heaters and fill valves with mineral until the tank rumbles or the fixture dribbles. None of that requires a famous storm. It does require an honest description of the age of the house and where the water is showing up.
Shut the water off if it is damaging finishes, and save the failed fitting if it was cut out. If sewage is coming up through a shower while the street is flooded, stop using the drains. That is not a clog you force with more water. If the heater no longer keeps up, say whether the tank is in the garage, a closet, or the attic.
Have the address, slab or pier and beam, and a one-line description: slab leak, freeze break, sewer backup, or a heater that failed. Mention hard water if fixtures scale up faster than they should. Ask the visit to find the source before anyone talks about opening the whole floor. A calm, specific call gets the right tools to the door. Call the number on this page.
