Question: What can I do about low water pressure?
Answer: The pressure and flow rates in your home can be affected by a number of factors:
- The height of the property above the water main and its height in relation to the local storage reservoir (the higher the elevation of the property the less pressure you are likely to receive)
- The condition of the service pipe (the smaller the pipe and the older it is, particularly if made of lead or galvanised iron, the greater the loss of pressure as water is drawn through the pipe)
- Whether the property shares a supply pipe with other properties (usually within flats). The higher the flow, the greater the loss of pressure by the time it reaches the kitchen tap • Peak demand conditions (the time of day most people are drawing water from our network, typically breakfast time and tea time. Higher demand equal lower pressure
- Your internal plumbing (if you have long pipe runs within your property the water has to travel longer distances through the pipes and the potential for pressure loss is therefore increased).
If you are experiencing low pressure continuously, check that your internal stop tap is fully open. If you are able and it is safe to do so you can also try turning your external stop tap.
In most cases your stop tap will be installed at the boundary of your property. If you are on a water meter, you may have a stop tap that is installed inside the meter chamber.The stop tap will either be a plastic head which needs to be turned 90 degrees to its open position or, if it’s a brass tap this needs to be unscrewed until it reaches a natural stop. At the same time you can also check that you do not have a leak on your supply which may be causing the low pressure.
