Water Meter\Electrical Earth?

[Greenbeast]

Thinking of getting a water meter fitted, the water board say i need to make sure that if i have an earth connection on my water pipe that it gets moved becase they will be breaking the connection by fitting plastic pipes.

My jack-of-all-trades step-father informs me that if my electricity supply/CU is earthed on the gas meter then i need not worry about the water pipe earth

Is this true?

My supply does seem to be earthed onto my gas pipe so is that problem averted?

Thanks

no

no

your metal water pipes should be bonded where they enter the house, on YOUR side of the stop-cock, with 10mm G&Y

Perhaps he still thinks houses derive their supply earth from water mains. This is not true, and has been against regs for something like 50 years. The earth bonds you see serve a different purpose, which I wont go into here.

well my house is 120 years old, so i've no way of knowing how old the electrics are

i read the link and tried to understand as best as i could

am i going to have to pay for an electrician to come in to tell me i do or do not have to move an earth on the water pipe?

thanks

Stick a few pictures of your fusebox/meter/electricity service area on imgaeshack and we can try and identifiy the earthing arrangements for you
