A burst pipe has a split or break that releases a large amount of water quickly, while a leaking pipe lets out a smaller, steady drip from a pinhole, crack, or loose joint. Both need repair, but a burst pipe calls for shutting off the main water right away.
What a Burst Pipe Looks Like
- Water spraying, pouring, or rushing from a pipe
- Sudden flooding on a floor or through a ceiling
- A sharp drop in water pressure throughout the house
- A loud hiss or rushing sound inside a wall
Bursts often happen when frozen pipes thaw, when old pipes fail under pressure, or when a fitting suddenly lets go.
What a Leaking Pipe Looks Like
- A slow drip from a joint or valve
- A damp spot or stain that grows over days or weeks
- Green or white crust on fittings
- A water bill that creeps upward
Leaks are often caused by corrosion, worn seals, or small cracks. They can go unnoticed for a long time because they are slow and often hidden behind walls or under cabinets.
Why Both Matter
A burst pipe causes fast, obvious damage. A leak causes slow, hidden damage that can rot wood, ruin drywall, and lead to mold. A small leak can also be an early warning that a pipe is weak and may burst later, especially in cold weather.
Responding to Each One
For a burst, close the main valve immediately and keep clear of wet electrical areas. For a slow leak, close the nearest fixture valve if you can, catch the drips, and plan a repair soon. In both cases, do not rely on tape or clamps as a lasting fix.
When a pipe has split open, replacing the broken section is the safe fix. If you are not sure how serious a leak is, you can ask a plumber to look it over by calling (833) 603-1840.
