what's the point of having to run in a 10mm cable to the incoming water supply if it's blue elkathene plastic pipe,and the rest of the plumbing in the building is in hepworth plastic.My boss says we have to get the plumber to fit a 6inch piece of copper pipe after his plastic stopcock so as we can fit our earth clamp.Surely the water itself is a poor conductor.?

As per OSG 4.4 (p29):
"There is no requirement to main bond an incoming service where the incoming service pipe and the pipework within the installation are both of plastic".

Just make sure that there is no metal pipework in the house before taking this into consideration :). Cover yourself.

This guide should be printed in large letters on the side of every electritians van in the land!:D

Then you get the situation where the kitchen fitter has changed the plumbing and the stop cock is still copper then there's 6ft of plastic and then back to copper, where oh where are we supposed to clamp the 10mm earth bonding cable?

This a very tricky subject and can only be cleared by taking each installation as it comes.

The only way you can be sure if bonding is required or not is to test the resistance between the incoming pipework and a local CPC.

....or 6" of copper then a carbuncle of plastic push fits where the kitchen fitter has thrown his proverbial spanner in the works

Hi guys, thats what i got told, just to run 10mm to main water in and leave there incase it gets changed at a later date????
Suppose if they pay me for it i dont mind.:D

In the IEE wiring matters mag I'm sure it said that bonding things when the plumbing installation was done in poly pipe actually made it a greater risk. :eek: I'll need to dig out the mag though......

One of the lads at work did this but there wasn't any copper so he bonded to the plastic pipe, very silly of him. The pipe then burst covering him and the house he was rewiring with water.

If you have plastic push fittings in the copper pipework you should install a bonding conductor across the fitting to maintain the conductivity.

See Pic. :)

Warren,

If it was one or two then I could understand this.

The problem is the kitchen fitters use them like they are going out of fashion.

It is not uncommon to open the cupboard door under the sink and see a dozen of them in a maze of pipework and then there is the stuff you CANNOT see or even possibly get at behind the other cupboards / boxing in / floorboards. When it is like that, there is no real practical reasonable answer.

I'm a kitchen fitter,who uses end feed solder fittings(cheaper).

This situation with the earthing requirements is confusing,so I just earth it all,unless its obviously all plastic.

On a similar theme,how does ptfe tape on gas affect the electrical conductivity?

you would probably have tapered threads and the threads would bite thru the ptfe so I doubt it would affect it.

Why not clamp the plastic pipe to make appoint and also charge for that:D

You must put the bond to the incoming service within 600mm of it entering the property anyway.
 
S

Spudnik

Sometimes if you talk nice to the plumber, he may put in a short piece of copper from the main stop cock for you to attach your clamp to.

I thought that the idea to bond to the water and gas was all part of the means of ADS if the incoming water / gas is plastic what possible good does it serve?
 
S

Spudnik

No it doesnt but i would always run the cable anyway and the bit of copper serves as a termination point.
