    I would say yes m8, electric currents will travel through water in the pipes. Is there no metal pipes close by to attach an earth clamp to?

    No mate you dont need to. Not coz of the fact that the pipes are plastic but for the fact that the Wiring Regulations Dont have earth bonding the sink as a legal requirement anymore.

    But if the facility is there then it may aswell be utilised

    Is anything else earthed in your house? If not, as far as I know, you can earth the copper pipes from wahing machine or something similar but PLEASE double check with a sparky

    I never got a straight answer to this from plumbers when I was fitting out a house last year, so the whole bathroom is plastic and visibly terminated in the kitchen where I used copper for the long straight runs. It all passed, though one thing you deffo need is an earth strap from just above the stopcock, 10mm single earth all the way back to the electric DB. You also need a single bond between the hot'n'cold copper water pipes if there are any, and all copper underneath the boiler has to be bonded together with 4mm earth.

    I've never had to earth a sink, generally they don't have any earthing points....

    Just did my kitchen sink today m8.Normally the copper pipes are earthed with a bonding clip and an earth cable link between them.Reason was to earth taps/steel sink if its there in case of the usual electric appliance thrown into a sink full of water while your hands are doing the dishes,I dont think.Really its if a bare live was in contact on your plumbing system you would not fry if earthed.
    Anyway ,as the pipes are usually plastic push fit to the taps or similar you dont earth plastic.What I did just as a usual precautionary,was to link the earthing bond I have between the copper pipes under sink to a metal clip that hold sink onto worktop underside,and that made contact to earth all round.Its only a complimentary earthing but not a problem.
    I hope you are having better luck with kitchen than I am.I am doing a a bit every day and its taking forever.

    Lets just have a moan !!!!

    Cool.

    thanks for the replies. Decided not to bother earthing as its all plastic pipes. Have to say though i am completey done in. This is the first time i have had a wee break to have a shifty at pc since thursday night. Been working solid every day. Its amazing what problems you can encounter when doing your own diy. I have had a major major problem with my drainage from the kitchen which runs down behind the sink all the way along the all the cupboards are against. Its about 18" off the ground so i cannot put cupoards against the wall meaning the worktops i got at 620mm are actually now having to sit practically flush with the units when they should have about 20mm overhang. I have had to bulk out this same very wall so that i can put tiles and have them just sit on the worktop and nomore. there was still a gap of about 1" before i did this. The bugger about this is that i alos had to move a few sockets as hob was now going to be sitting right below them. I amnaged to move them just the right amount with the wire supplied but the kitchen socket was counter sunk into the brick wall as the box is quite deep. where i wanted to put it was not counter sunk so had to then punch a hole in the brick work to accomdate this. eventually got it the way i liked it before i realised i would have to bulk out the worktop anyway so it would probably have been fine sticking out the 1cm or so it was at the time. Also on the plumbing one of the joins on the push fit t pipe was leaking as the washer in the insert connector going into the t-pipe had twisted. Nice wee puddle of water and had to redo fittings which was a pain in the arse at this point as it was all now neatly snug under the kitchen sink.

    my arms, neck and especially my fingers are all aching. My fingers feel like they have arthritis or something and i have hurt my wrist. But the joy of seeing the kitchen sink with running water and the oven & hob not exploding, the kitchen units staying on the wall in a staight and neat fashion and the fact my wallet is not 1200 lighter (which is waht some idiot was going to charge me for fitting) had made it all worthwhile.

    I think the worst part was walking about trying to remember where exactly i had just left the thing i was using two minutes ago... Did this so often it was just plain painful.

    Plus i have learned loads........... like just pay someone else to do it next time .
