Helping with water pressure concerns

Customer contacts about low pressure this month:


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

When you turn your tap on, you can expect your water pressure to have enough force and volume to easily fill a kettle or glass for example.

Pressure is measured in a unit called ‘bars’, with one bar equalling the force required to raise 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.

If your pressure is low, it could be for a number of reasons….

1. Find out if the whole property is affectedit'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 openYour 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 neighboursIt 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. Report it If you still have low pressure - let us know. We will then be able to investigate whether the problem lies in pipes belonging to us or you and advise you on the next steps.
