Sudden loss of water pressure is generally caused by a burst pipe or major blockage. Slowly reducing pressure usually means a growing leak or blockage.
Fluctuations in pressure can occur on shared service pipes which supply several properties, particularly if they are deteriorating due to old age. The deeds for your premises should show whether you have a shared service pipe.
We offer a free water pressure checking service during normal working hours. If the low pressure is our responsibility, we will take action. If not, we will advise you what to do. Simply contact our Customer Service Team on 01737 772000 to arrange for one of our Network Inspectors to visit.
Pressure and flow rates can be affected by:
- The height of the property above the water main, and its height relevant to the local service reservoir
- The condition, size and length of the service pipe
- Whether the property shares a service pipe with other properties
- Peak demand conditions
Typical water pressure
The Water Industry Act defines the minimum level of service that should be provided for a water supply. For single supplies, we must ensure that we provide a flow rate of 9 litres per minute at a pressure of 10 metres. This flow rate is equivalent to filling a one-gallon bucket in 30 seconds. This level of pressure ensures that the supply can fill a storage tank at second floor roof level.
