Main bonding

[haj]

Hi Gentlemen
A question regarding bonding the main water. The main water pipe intothe property is lead and runs upstairs before any copper is fitted. What is the common practice with lead water pipes ?
Thanks in advance for any advice given.

Still need bonding but within 600mm of it entering the property.
However i would recommend getting rid of the lead!!!!!!

Maybe i need to do a quick plumbing course how hard can it be ? Do i just use an ordinary earth clamp ? I like the sound of getting rid of the lead !! ALL scrap cash into MY pocket please

Not so much the scrap value, but more to the health of the homeowners.


951 clamp will be fine but just dont over tighten it.

Know what you mean about the health issue i have already pointed that out to the home owner.
Thanks for the reply

They had a thread a little while ago on this mate.Just bond to the copper pipe and note it on the cert.http://www.electriciansforums.net/e...trical-regulations/7040-bonding-pipework.html

As Mac said and don't worry about the 600mm guidline, most people forget the WHERE PRACTICABLE bit of regulation 544.1.2. Also a BS 951 clamp should be connected to hard not soft pipework so your connection to the nearest copper is quite acceptable and covered by the terms of the stated regulation.
Hope this helps

if you come across any lead piping you are supposed to replace.
Having said that, at our place the main incomming supply is lead. My misses has lived there nearly all her life (25) and not done any harm, and all i drink is water. Probably coated in limescale though lol

Cheers guys think i will go to the first bit of copper to get a good tight clamp and put a note on the cert.
