What to do the minute a pipe breaks
- Close the main water valve. Know where it is before you need it. In most Lee's Summit houses it sits on the basement wall closest to the street.
- Open a faucet on the lowest floor to drain the pressure out of the lines.
- Kill power to rooms where water is coming through the ceiling if you can reach the breaker panel safely. Ceiling light fixtures fill with water.
- Call. A plumber fixes the pipe. A water damage crew deals with the wet walls, ceilings and floors. Get both moving at the same time.
- Poke a small hole in a sagging ceiling over a bucket to let trapped water out in one place, if you can do it without standing under it.
Why burst pipe damage spreads
A supply line runs at full house pressure, so a split pipe can put out several gallons a minute. When the break is upstairs or inside a wall, the water runs along joists and down wall cavities, then soaks the ceiling below and the floor under that.
That hidden spread is why crews open walls and ceilings instead of just drying what you can see. They use moisture meters and thermal cameras to find wet framing and insulation, then cut access holes so air can reach it. Wet insulation usually has to come out. Skipping that step leaves water in the walls that turns into mold and rot.
Frozen pipes in Lee's Summit winters
Missouri winters swing hard. A mild week can give way to single digits overnight, and the region has seen record lows far below zero. The pipes that freeze are the ones near the cold: lines in exterior walls, kitchen sinks on outside walls, hose bibs, plumbing in garages, crawlspaces and bonus rooms over garages.
The break usually shows up after the cold snap, when the pipe thaws and the crack starts spraying. That's why so many burst pipe calls come in on the first warm afternoon after a freeze, or when a family gets home from a holiday trip.
Newer homes in Chapel Ridge, Blackwell and New Longview mostly have PEX plastic lines, which handle freezing better than copper but still split at fittings. Older homes downtown and in the Howard District may still have galvanized steel or copper runs that were never insulated.
A few habits help when the forecast drops below 20 degrees. Open cabinet doors under sinks on outside walls, let a faucet drip, keep the thermostat at 55 or higher if you travel, and disconnect garden hoses so the outdoor spigot can drain.
