Water pressure is a measure of the force pushing water through our mains and into your property.

Pressure is measured in a unit called ‘bars’, with one bar forcing water to a height of 10 metres. As part of our customer promise, we aim to ensure that your water pressure is no less than our target of one bar at the boundary of your property.

In a typical two storey house:

• Water will rise and fill a storage tank in the loft
• It should take about a minute to fill a 10 litre bucket with water from your kitchen tap

If your pressure is low, it could be for a number of reasons, check our advice below for more information.

1. Find out if the whole property is affected
If it's only certain rooms in your house, such as your bathroom, it's likely to be an issue with your plumbing and you need to contact an approved plumber.

2. Check your inside stop tap is open
Your inside stop tap can usually be found where the water enters the property. In a house this is often under the kitchen sink or in a downstairs toilet.

1. Turn on the cold tap nearest to the stop tap
2. Carefully turn the stop tap anti-clockwise to turn on and clockwise to turn off a few times. This should free any airlocks or blockages in the pipes

3. Check with your neighbours
It may be useful to check with your neighbours to see if someone has turned off your outside stop tap – perhaps to carry out building work, or repair a leak. This is most common in terraced properties or flats which may share a water supply pipe.

4. Use our live map to search for incidents in your area
If steps 1 to 3 don’t work there may be a problem in your area. You can check our live map to see if we’re aware of any work in your area.

5. Report it
If you still have low pressure - let us know. We will then be able to investigate your problem and advise you on the next steps.
