How to check for a leak at home
If you think you have a leak at home, there are a few ways you can test your supply to check before you get a plumber in to fix it.
Check for the first signs of a leak
When you have a leak, spotting these early signs might help you to get it found and fixed early, before it becomes a bigger problem. The first indications of a possible leak can be seen inside and outside your home.
Things to look out for include:
- a wet patch in your grass or paving
- an area of grass growing much quicker than that around it
- sunken patches or slabs of paving
- a change in water pressure
Tests you can carry out yourself
How to check for a leak if you have a water meter
If you have a water meter, this test might help you. However not all metered customers will have the kind of meters that allow you to carry out this test. If your meter is internal, complete the following steps:
The reading on your meter should not have changed during the time between the two readings.
If the meter reading has changed, this could mean that you have an internal leak. You will need to contact a plumber to carry out the repair.
If you’re unsure, you can contact Severn Trent and request a free diagnostic visit from one of our engineers, who will identify the cause.
If you have a digital meter with an LCD screen and the reading has changed at this point, we may need to inspect your meter to make sure that it's working properly.
You can get in touch with us to arrange a water meter inspection.
If your meter still shows the same reading after completing the first part of the test, you should continue by following these steps:
1. Turn your internal stop tap on.
2. Wait ten minutes, making you still don't use any water.
3. Take a note of the meter reading.
If the meter reading has changed, this would indicate there is an internal leak at your property.
How to check for a leak if you’re not on a water meter
If you're not on a meter, signs of a leak could include:
- A change in water pressure
- Visable water or damp
If you think your water isn’t flowing as it should, you can carry out a quick test to check your water pressure. If your water is flowing properly, it should fill a litre container in about 7 seconds. If it takes much longer than this, there may be a problem with your water pressure.
Check for known problems in your area before you contact us as it may already have been reported.
