Often older houses, mostly terraced houses and occasionally some semi-detached houses, use a common supply pipe system (Shared supply). This is a pipe that supplies the water from the mains to two or more properties using a shared stop tap. In effect this means that you share the supply pipe that branches off from the mains with your neighbours.
For some properties, the problem is caused by sharing a supply pipe from the water main. This can be a problem if the supply is too small, in poor condition (for example, leaking or old), or if properties sharing a supply use water at the same time. It can also be particularly noticeable at busy times when many properties sharing a supply pipe are placing demands on the water supply. So, a supply that seems fine at sometimes of the day may not be at other times. If you and your neighbour share a supply pipe, you are jointly responsible for it from your property to the boundary stop tap. The houses in the example have a shared supply pipe and a joint responsibility for maintaining and repairing it. If you have reduced water pressure and you are on a shared supply pipe, talk to your neighbours to see if they are experiencing the same problem. If so, you may want to look at installing a separate independent service pipe from your property to the water main or, at a joint cost, renewing / increasing the size of the shared supply pipe.
EPS can install an individual supply to your property.
