Do you want to know the water pressure in your street? Are you having a new shower, boiler or other appliance fitted?
Please contact us if you would like to know the pressure in the water mains feeding your property. Call 01202 590059 or email email@example.com. (Calls are answered in person from 8 am until 6 pm Monday to Friday and from 9 am to 2 pm on Saturdays.)
The pressure will depend on your location and may vary at different times of day. Water pressure can be affected by many factors, such as:
There may also be a difference between the pressure in our mains in the road outside your home and the pressure inside your home. This could be due to:
We must comply with certain standards set out in the Water Industry Act 1991 Part III Chapter II "Means of Supply " Section 65.
We are required to supply water constantly and at a pressure which will reach the upper floors of buildings. This does not apply to buildings using pumped systems, such as blocks of flats. We are not required to supply water to a height greater than that to which it would flow by gravitation through our water mains from the reservoir.
For more information on water pressure, go to the website of the water industry regulator, Ofwat.
We must supply a pressure of not less than ten metres head (1 bar). This is the height that water would reach in a vertical pipe. This pressure level applies to the communication pipe supplying your property (the pipe that goes from our main, usually to the boundary of your property) for a flow of nine litres per minute inside the property.
In most areas the pressure is higher than this. Our regulator, Ofwat, requires us to report the number of properties that receive pressure lower than this standard each year.
The minimum standard for pressure is called ‘the level of service indicator’, known as DG2. This level of service does not override our duty to supply water constantly at a pressure to reach the upper floors of properties.

Water meters have important benefits for you, for us and for the environment as you can have more control over your water use and leaks are easier to detect.
