Who's qualified Ask for proof of insurance, relevant certifications (e.g., ASE for auto repair), and any license your state or city requires.

Where is the main water shut-off valve?

Locate the main shut-off valve in advance, because a burst can cause major flooding during extreme cold. If the fixture shutoff does not stop the flow, turn off the home's main water shutoff valve immediately.

What do I do today if the pipe is still leaking?

Stop using the fixture until a professional arrives. If the shut-off valve does not work, call KC Water right away for an emergency shut-off, available seven days a week at 311 (816-513-1313).

What if I'm in Lenexa and need emergency shut-off help?

WaterOne provides a 24-hour emergency contact number, 913-895-1800, for emergency shut-off help in the Lenexa area. Use it for water-related emergencies after hours.

How do I prevent a burst pipe from happening again?

Leave a small stream of water running from a faucet during freezing conditions. Insulate exposed pipes with foam sleeves or heat tape, and keep cabinet doors open so warm air reaches the pipes.

What to do next

  1. Find the sink's supply valve under the fixture and turn it clockwise until it stops.
  2. If water keeps flowing, close the home's main shutoff valve right away and open a faucet to drain pressure.
  3. Call WaterOne at 913-895-1800 or KC Water at 311 if the valve is stuck or broken.
  4. Ask the pro for proof of licence and insurance and get the repair cost in writing before work starts.
