Leak detection

Leaking water pipes can occur almost anywhere - from within the newest homes, to the smallest gardens and the tallest buildings.

The challenge of finding and fixing leaks never ends.

How much water are you wasting?

Fixing leaks saves water and money.

You can lose a few litres of water an hour from a slow dripping tap and thousands of litres a day from a constantly running toilet.

If the leak is from a hot water pipe or a pumped water supply, you'll also be facing a significant energy cost. 

That makes fast detection and repair even more important.

We're responsible for the meter on your property, but the property owner is responsible for all other pipes and fittings that connect to our water network.

The meter typically has an isolating valve next to it. This is commonly called the 'meter tap'. This helps when we need to replace the meter, but it also stops the water supply if you need to fix a leak in your home.

What should you do if you find a leak?

If you have a leak, call a licensed plumber.

If you can detect a leak using your meter but can't locate it, a leak detection specialist will be able to help.

Not all plumbers have the special tools and skills needed to find leaks hidden underground and inside walls. Our WaterFix®  service provides a full range of leak detection and repair services.

How can you check for leaks?

If you have your own meter, this simple test will only take a few minutes.

For this test to work, it's important not to intentionally use any water at your property. 

How to check for leaks using your water meter

  1. Turn off all taps and water-using appliances.
  2. Locate your water meter. It's usually at the front of your property.
  3. Write down the black and red numbers on the dial of the water meter. See How do you read the meter for more information about the numbers on different types of meters. 
  4. Wait for at least five minutes.
  5. Check if the last numbers on the dial have changed. If the numbers have changed, you have a leak. The greater the change, the bigger the leak!

Almost all of our customers have water meters, but you may share a meter with your neighbours. This makes it hard to tell if any leaks are in your pipes or your neighbours' pipes.

Simple ways to look for leaks

If you know what to look for, you can check for some common sources of leaks around your home.

  • Check your hot water system's expansion valves when you haven't used any hot water for a while. The valve shouldn't be constantly leaking water.
  • Check your taps and toilets regularly for signs or sounds of leaks.
  • Disconnect hoses or irrigation pipes that are always connected to garden taps. Then check the taps aren't leaking. 
  • Place a small piece of dry toilet paper at the back of the toilet bowl and check that it stays dry until the next flush. Toilet cisterns shouldn't release any water between flushes.
  • Look for green patches of grass that are different from the grass around it. This can mean you have an underground pipe leak.

If you suspect you have a large leak, you'll probably need help from a plumber with specialist equipment.
