Bonding for Pipes

Key point:

If there is ever a need to remove the earth bonding cables from pipework fitted in the home, it must be replaced as soon as possible as this will allow pipes to become live if they contact with bare electrical cables. If you are not confident and at all uncertain about your bonding, then it is wise to seek the advice and skills of a professional tradesmen with the necessary experience and understanding. If you ever get the time, take a look at your gas meter or maybe your incoming water supply and you will or at least should see a green and yellow wire connected to the pipe, you may wonder what that is for.


It is called an earth bonding connection cable. The bonding consists of cables that have are green with a yellow stripe, and are quite different from all other cables in the home. They are clamped to water service pipework on entry to the house and also on pipework in rooms such as your kitchen and bathroom. Power Flush London tradespeople can advise on this. Pipes in your home that are metal and carry fluid are always at risk of becoming live, from stray electrical currents, resulting from faulty electrical equipment. These stray currents pass through the pipework as they flow down to earth that can be dangerous for anyone touching the metal pipework itself. A specifically designed electrical route is required through a bonding wire of 10mm2 minimum that is attached to the pipe at the point of entry/exit of the building and this is connected to the main earth terminal in your consumer unit. In addition to the bonding wires for the incoming services, there should also be additional cables linking together all the metalwork within any area that is wet, like a bathroom and kitchen etc. This guarantees that everything within that zone is at the same electrical potential, which is designed to prevent users of any appliances or equipment receiving an electric shock. Power Flushing London plumbers are trained to deal with electric shock.
