Do water pipes need to be earthed?
You do not have to earth plastic pipes They know that the risk and severity of an electric shock is increased as a result of the presence of water. This may be the reason for the concern that water in plastic pipes may conduct electricity and that bonding is required.
Is earth bonding still required?
Supplementary equipotential bonding (between waste pipes, metallic service pipes and earth connections of bathroom equipment) is no longer required if, and only if, the main bonding between metal service pipes can be proved to be continuous.
What is needed for earth bonding?
These should connect to 1) water installation pipes 2) gas installation pipes 3) other installation pipework and ducting 4) central heating and air con systems 5) exposed metallic structural parts of the building.
Why do you need to earth copper pipes?
That’s called ground/earth bonding, and it’s done to make sure that if the copper pipe work comes into contact with a live wire due to a fault that it trips a breaker and doesn’t electrify all the pipework in the house which would be extremely dangerous.
Who is responsible for earth bonding?
The responsibility for earth bonding to the gas service pipes, is yours. You are connecting to the consumers side not the suppliers/providers side, the pipework you bond to belongs to you, not Transco.
What is the difference between earthing and bonding?
So why do we earth and bond? Without the earth connection, the metal outer casing of the washing machine could become ‘live’. The principal of earthing is to prevent this situation occurring, by limiting the duration of touch voltages. Bonding is a connection of all metallic parts using a protective bonding conductor.
Do I need equipotential bonding?
Supplementary or additional equipotential bonding (earthing) is required in locations of increased shock risk. In domestic premises, the locations identified as having this increased shock risk are rooms containing a bath or shower (bathrooms) and in the areas surrounding swimming pools.
Why is there an earth wire on my water pipe?
Earthing is used to protect people from the risk of electric shock. This is to reduce the risk of electric shock where people may touch two separate metal parts, such as radiators and water pipes, when a electrical fault occurs in the electrical installation.
Why do you need bonding on water pipes?
It’s a common misconception that all water pipes require protective bonding to be installed. Protective bonding is installed to prevent Earth potential from outside the installation being brought inside. A plastic pipe is not conductive, therefore it cannot introduce Earth potential into the installation.
Where should the gas pipe earth bonding connect to?
The CU will be next to the incoming 100A fuse in the under stairs cupboard, the gas meter is in the detached garage. It would be a bit of a pain to route the 10mm earth cable to the gas meter, and a lot easier to connect it to the 22mm copper pipe that runs from the meter, up the outside house wall and then inside to the boiler somewhere.
Can a plastic pipe be used for earthing?
A plastic pipe is not conductive, therefore it cannot introduce Earth potential into the installation. However, it must be verified that there are not any fortuitous connections with Earth throughout the installation.
Do you need a supplementary bond for an Earth Bath?
A supplementary bond is notrun back to the main earth 3. Metal baths are supplied by metal pipes do not require supplementary bonding if all the pipes are bonded and there is no other connection of the bath to earth 2.

Do you need supplementary bonding for plastic pipes?
That is not to say that supplementary bonding in a kitchen or wash room is wrong (it would be wrong for plastic pipes!) but it is not necessary. For plastic pipe installation within a bathroom the plastic pipes do not require supplementary bonding and metal fitments attached to these plastic pipes also would not require supplementary bonding.
