Understanding how to shut off your home's water supply is crucial for any homeowner or tenant. Whether you're dealing with a plumbing emergency or preparing for a home improvement project, knowing how to properly turn off the water can save you from potential water damage and costly repairs. This guide will walk you through the simple yet vital process of locating and turning off your water stop tap.

Essential Tools & Equipment

Step 1: Locate and Identify the Stopcock

  • Common locations include under kitchen sinks or, in the bathroom. 

  • If you can’t find it, follow any plumbing pipes around your home and you’ll eventually come across the stopcock.

  • Use a flashlight if the area is not well-lit.

  • The stop tap typically looks like a standard tap head.

Step 2: Turn Off the Water Supply

  • Turn the tap clockwise fully until it cannot turn anymore.

  • This action will cut off the water supply to the entire property.

  • If the stopcock is stiff, use an adjustable wrench or gloves for a better grip.

Step 3: Drain The Pipes

  • Some water will still be in the pipes, so you should open an upstairs tap until it stops draining to empty the pipes.

  • Once the pipes are empty, you can start plumbing work.
