Not all leaks are created equal. A slow drip under a sink is a very different situation from water actively spraying out of a wall, and the right response depends on which one you're facing.
Minor, Contained Leaks
For a small, steady drip — say, from a supply line or fitting — placing a container underneath and shutting off the local supply valve, if there is one, can buy time until a repair is scheduled.
Active or Spreading Leaks
If water is actively flowing and doesn't seem to be slowing down, shutting off the main water valve is the priority. From there, move belongings away from the water and call for help.
Hidden Leaks
Some of the most damaging leaks aren't visible at all. An unexplained rise in your water bill, or the sound of running water when everything is off, can point to a hidden leak behind a wall or under a slab. See our leak detection page for how these are typically found.
After the Water Is Stopped
Once a leak is under control, drying out the affected area promptly helps limit further damage, and a professional can assess whether the pipe itself needs repair. Our pipe repair page covers common causes of pipe failure.
