All domestic water is supplied by a service pipe, also known as a rising main. This is connected to the local water authority's main which runs under the highway. There will be a stop cock where the rising main tee's off the water authority's main, this provides a means of isolating the supply to your property, should an emergency or any repairs be required. The homeowners responsibility begins where the rising main leaves the public highway and enters their land.
The rising main in modern properties is made from plastic, although in some older properties this could be lead or copper. There is another stop cock where the rising main enters your building, this could be in a number of places. Common locations are:
If you don't know where the stop cock is in your property then find out as soon as possible, when water is dripping through the ceiling is not the time to start looking.
Most homeowners rarely have to carry out major plumbing jobs and in most cases it is usually safer and better to employ qualified tradesmen, but being able to tackle small installations or repairs can save a lot of time and money.
If you choose to modify existing or install new plumbing then you must adhere to local water authority regulations. These regulations are designed to safeguard public health and reduce risk of contamination or wastage.
Contact your local water authority for the relevant information.
You must also adhere to any relevant electrical regulations, these are also designed to safeguard anyone against injury. Certain sections of plumbing must be earth bonded, if any sections are replaced with plastic then an earth bonding link needs to be fitted. If you are in any doubt consult a qualified electrician.
