Bonding For Pipes

The majority of pipes in the home are metal in construction. These are being replaced by plastic versions in a lot of new build properties, however most of us still have copper pipes that can under the right conditions conduct electricity which is very hazardous to health. So there is a risk that someone could receive an electric shock from touching these pipes. To make sure the risk is kept to a minimum, the pipework is connected to the main earth point in the consumer unit. The pipework has cable links at various points along its length, also secondary cables are fitted to link the pipes as they go through the home and continue the bonding to earth. The cables are connected by small metal clamps to the outside of the pipes. Should there be a need to cut and remove a piece of pipework you must replace the bonding cable. Therefore if you are uncertain, it is a good idea to ask the advice and employ skills of a professional.

Equipotential Bonding:
The bonding or ‘equipotential earth bonding’ as it is known in the trade is not just fitted to the pipes in your home. It can also be connected to other appliances such as the gas meter or even your incoming water supply pipework and valves. If you are not sure about the cable it is green and yellow, that is yellow with a green stripe. Hackney Plumbers use earth bonding cable. This cable is a wire of 10mm in diameter. Earth bonding will terminate as stated earlier at the main consumer unit or fuse box for the house. The earth point is easy to see. This bonding guarantees that everything connected is at the same ‘potential’ electrically (hence equipotential). The only way an electrical current can flow is when there is a potential difference, therefore things at the same potential are fine and will not conduct, resulting in no electric shock risk. A Hackney Plumber is trained to deal electric shock. So you can see that equipotential bonding although redundant most of the time can when required, save your life.
