How do I turn on my water supply?

Published in Plumbing Basics 2 mins read

Turning on your water supply typically involves turning the main stopcock valve counter-clockwise. However, the exact method can vary depending on the type of valve and its location.

Here's a more detailed explanation:

  • Locate the Main Stopcock: This is the primary valve that controls the water supply to your entire property. Common locations include:

    • Near the water meter.
    • In a basement or crawl space.
    • Under the kitchen sink.
    • Outside, near the property line (often in an underground box).
  • Identify the Type of Valve: There are a few common types:

    • Gate Valve: These usually have a round handle that you turn multiple times.
    • Ball Valve: These have a lever that you turn a quarter-turn (90 degrees).
    • Stopcock: A smaller, handle-operated valve.
  • Turning On the Water:

    • Gate Valve: Turn the handle counter-clockwise. You'll likely need to turn it several rotations until it's fully open.
    • Ball Valve: Rotate the lever a quarter-turn until it is parallel with the pipe.
    • Stopcock: Rotate the handle counter-clockwise.
  • Important Considerations:

    • Turn Slowly: Opening the valve too quickly can cause a pressure surge, potentially damaging pipes or appliances.

    • Check for Leaks: After turning on the water, inspect all pipes and fixtures for leaks.

    • Flush the System: Run taps for a few minutes to flush out any air or sediment that may have accumulated in the pipes.

If you are unsure about any of these steps or encounter any problems, it's best to consult with a qualified plumber.
