Eicr no visible main bond to water services

[Pico1978]

Hi all, it's been a while but been busy in work and setting up my fledgling company I have a question, have a eicr tomorrow on a ground floor ex council flat. Had a look round earlier and can't find the main equipotential bond to the water but it is visible at the met in the db, if the bonding is under 0.05 ohm near the stop clock, with the gas bond disconnected can I class this as a c3? The supply is tt BTW not that it should matter, any advice greatly appreciated

No, I think you need to carry out some tests and you may find the conductor with a bit more investigation, all this before you decide on a Code.

dog reel or long lead for testing continuity?

Well, if the pipework records 0.05 Ohms to the met, I can't think how it could be that low except if there was a nice cable in place, somewhere. Otherwise it would likely be >10 Ohms on a TT, wouldn't it ?

 

[westward10]

Didn't spot the tt bit. There is every chance that tests would theoretically suggest it is a water bond by disconnecting and reconnecting it.

Agreed, just dont want to charge extra to install a bond from the db, although wouldn't be much cost - about 15m cable plus trunking, just been having a mare lately, 2 Rcd faults in a week or so, one a mem board with a functional earth causing probs, as I said a new business, just want to ensure everything is cosher, hanks for all replys

Thanks not hanks

Do the EICR and consider remedial costs after and don't be blinded to other matters by proving or disproving the water bond. Me I would get the job done then spend a bit of time on the bond problem.

Thanks westward10 that was my gut instinct

Oh the joys . If you have looked in all the usual hidden places they may have bonded it in a pipe box going to the upstairs flat . Councils do strange things.
I worked in one where all the rewired cables come down the exterior wall cavities back to CU. Circa rewire 1984.

With all the sticker we have to put on boards these day i sometimes think a bonding location sticker would be a good idea.
Sometimes people don't even know where there water/gas come in.
Yes i know i could make one myself

I agree about the labelling. Would be more use than most of the other labels usually stuck to a board. Here's one I did earlier.

I was going to like that HS #26 but someone's nicked the like button ...

 

[westward10]

Me too. About 15 years ago I submitted a request to the IEE that this should be a requirement and it was put forward for consideration but I received a letter back stating it wasn't necessary, still got it somewhere.

 

[Pico1978]

Again thanks for all advice, landlord got no probs with me doing the water bonding, also found a dodgy socket no connection to the earth pin somehow, will complete this before issuing the cert

Oh ---- I forgot, the earth to the earth rod is about 10" from the wall, 10mm cable not buried so fine, but an obvious tripping hazard, needs conduit etc but wouldn't a conduit box etc pose more of a tripping hazard? Sorry but everything I see lately seems a mind bending issue
