Connections to Properties
We usually replace our stopvalve (also known as a stopcock), the boundary box, and the communication pipe (i.e. the part of the service pipe outside your property boundary). A key to operate the stopvalve can be purchased at our Head Office in Havant.
Inside your property boundary you are responsible for the pipework. This part (see diagram) is known as the supply pipe.
