How to do a leak test if you don’t have a meter
If you don’t have a water meter, carry out this simple test to check if you have a leak.
Before you start
You will need access to your internal stop tap.
If you need help finding yours, see our advice on how to find your internal stop tap.

1. Listen for a noise
Find your internal stop tap and listen for a hissing or knocking noise.
2. Turn off your internal stop tap
Turn off your internal stop tap to turn off your water supply.
You can check that your water supply is off by turning on your cold kitchen tap.
3. Listen for a noise again
Check if you can still hear a hissing or knocking noise coming from your internal stop tap.
If you can still hear a noise
There is most likely a leak outside your property – follow our external leak guide for advice.
If you can no longer hear a noise
There is most likely a leak inside your property – follow our internal leak guide for advice.
