The short answer

Shut off the Water

Your first move is to stop the flow. Find the main shutoff valve, usually near the water meter or where the supply line enters the house. Turn it clockwise until it stops. If you live in Sammamish, keep the valve location written down near your electrical panel.

If the valve is stuck or you cannot turn it, use a wrench for extra leverage. Do not force it past the stop. Once the water is off, open the lowest faucet in the house, often in the basement or on the ground floor, to drain the remaining water from the pipes.

Cut Power in Affected Areas

Water and electricity are a dangerous mix. If water has reached outlets, baseboards, or appliances, go to the breaker panel and switch off power to those rooms. If the panel is wet or you cannot reach it safely, leave the house and call an electrician.

For a minor leak where water stays away from wiring, you can skip this step. But if the burst is overhead or near a ceiling light, treat it as a hazard. Use a flashlight, not a lamp, to inspect the area until you know it is dry.

  • Turn off power at the main breaker if water touches wiring
  • Avoid standing water when reaching for switches
  • Unplug appliances only if the floor is dry
  • Use battery-powered lights in dark, wet rooms
  • Call an electrician if the breaker panel is wet

Stop the Active Leak

Once the main valve is closed, the burst pipe should stop spraying. But water may still sit in the line between the valve and the break. Open all cold water faucets, starting with the highest point in the house, to let gravity drain the system.

If the burst is in a single fixture, like under a sink, close the local angle stop valve for that line. Wrap a towel around the pipe to catch drips while you drain the system. This slows the leak while you get ready for the pros.

Remove Standing Water

Use towels, mops, or a wet-dry vacuum to soak up puddles. The longer water sits on wood, drywall, or carpet, the more damage it causes. Move furniture, rugs, and boxes out of the wet zone to a dry area.

For deeper water, a pump or a shop vacuum may be needed. If the water is more than an inch deep, or if it has soaked into flooring, let the pros handle extraction. Your job in the first ten minutes is to slow the spread, not to dry the entire room.

  • Sop up puddles with towels or mops
  • Move rugs and furniture off wet carpet
  • Lift wet curtains and drapes off the floor
  • Place buckets under active drips

Document and Call for Help

Take clear photos of the burst pipe, the water level, and any damaged belongings. These images help with your insurance claim later. Write down the time you noticed the leak and what you did to stop it.

Then call local water damage pros. They handle burst pipe cleanup, structural drying, and repairs. While you wait, keep the area ventilated by opening windows and running fans if safe. Policies vary, and your insurer decides what is covered.

Expect the pros to assess the moisture, extract standing water, and set up drying equipment. They may also trace the leak to find hidden damage in walls or under floors. Do not attempt major repairs yourself until the area is fully dry.

Frequently asked questions

How do I find the main water shutoff valve?

Look near the water meter, usually in a basement, crawlspace, or utility closet. In warmer climates, it may be outside near the street. Trace the pipe from your water heater backwards. If you cannot find it, ask a plumber to show you once.

What if the burst pipe is in the ceiling?

Turn off the water and power to that room first. This prevents water from spreading along the ceiling. Call the pros to handle the repair.

Should I try to patch the pipe myself?

Only if it is a temporary fix like a pipe clamp or epoxy putty, and only while you wait for the pros. These fixes are not permanent. A plumber should replace the damaged section to avoid another burst. Your priority is stopping the water flow.
