Do I need to pull the floor up?

[RenovateThis!]

I have recently put a new bathroom in (DIY) and during the course of the work I contrived to drill through the copper cold water pipe. After cutting out the offending piece I put in a plastic Speedfit straight connector. However, I neglected to reinstate the earth link when I put the plastic connector on and I have since re-done the subfloor and tiled it so access to the join is a little difficult.

What I need to know is do I definitely need to reinstate that link? After the plastic fitting there is a T join where it goes off to the bath/shower mixer (fed by combi-boiler so not electric) and then it runs to the kitchen where it ends. The kitchen pipes are bonded together just below the (currently metal, but soon to be ceramic) sink.

Obviously I would rather not have to get the floor up but it is playing on my mind. What do you think?

Any help much appreciated.

im no plumber or electrician

but surely if you have the hot and cold bonded together
upstairs and the same down stairs you have complete bonding
if you need it

Thanks b-a.

It's a one-bed flat so the stairs are surplus to requirements but if the principle you outline applies, ie bond at the start of every pipe run and also bond at the end then if I ensure the kitchen sink and bathroom basin are hot & cold bonded then I should be ok, no? (The bath/shower mixer are hot & cold bonded after the 'indiscretion').

And is there a 'Dunderheads Guide to Earthing' available in all good book shops

There's the OSG.

There are a couple of links in the reference section.

I'm told the NICEIC <wash my mouth> Snags & Solutions (IIRC) book is good too.

But if you really mean earthing and not bonding, try this: http://www.tlc-direct.co.uk/Book/5.1.1.htm
