What Is a Stopcock and Why You Should Know About It?

A stopcock is like the “master tap” of your home. It’s primary function is to control the water flow in your plumbing system – allowing you to shut it off entirely when necessary. Unlike the taps you use every day, stopcocks are rarely touched, which is why knowing its location and ensuring it works properly is crucial, especially during emergencies.

Why Is a Stopcock Important?

In a plumbing emergency, such as a burst pipe, acting quickly can save your home from significant water damage. Shutting off the stopcock stops the water supply to your property, minimizing potential harm before you call an emergency plumber.

Where Can You Find Your Stopcock?

The location of your stopcock can vary, but it’s typically found in one of these places:

  • Under the kitchen sink;
  • In the bathroom;
  • In a utility room;
  • Outside under a driveway or pavement.

If it’s outside, it will usually be under an iron cover that you’ll need a stopcock key to access.

How to Maintain Your Stopcock?

Because stopcocks are used infrequently, they can sometimes seize up or become stiff over time. Here’s how to keep yours in working order:

  1. Locate It
    If you’ve just moved into a new home, find the stopcock as soon as possible and ensure it’s accessible.
  2. Test It
    Check that the stopcock turns easily. Turn it off and on occasionally to prevent stiffness.
  3. Lubricate It
    If the stopcock feels stiff, apply a spray lubricant like WD-40 to the shaft. Avoid forcing it with tools like spanners, as this could cause damage or snap the handle.
  4. Regular Checks
    Periodically test the stopcock to make sure it hasn’t seized. This small habit can save you trouble during emergencies.
