Do you need to earth bond bathroom if it is on RCD?

techmob

my gas meter is bonded. the water isn't because it is an incomming plastic, is that ok?

does it go straight to plastic after the stopcock.?
if there is any copper it needs bonded. most good plumbers will install a metre or so to facilitate this purpose.
this is a generalisation, under certain conditions with a plastic install and a limited amount of copper a bond may be omitted, but TBH it involves technicalities and resistance measurements.

I will check this but i think it is a copper stopcock and then plastic straight from it.

a flickering light then not working sounds like a loose connection that has now 'blown off' .

blown off?

sorry what does that mean exactly?

thanks

basically if it 'was' a loose connection then the little piece of cable that was touching has now heated up and melted back slightly from the connection,
its not a major issue, dont get too worried about it.
if its totally plastic throughout apart from the stabbings through the floor then no need to bond, IMO,
though the plumber should have left you a bonding point after the stopcock,
he was rough.!!!

whoever did it before i got the house has left the old stop !!!! there and the new one comes in with plastic

yes, the new supply would most likely come in blue(probably) poly pipe to the stopcock, then the plumber should have put in a short piece of copper before his plastic pipework to allow an earth bond to be fitted.
its OK, but in all honesty I do think it was a bit rough of the plumber not to have done this, not like it would have been a lot of work at the time either.

Document isn't updated with the latest regs regarding not requiring supplementary bonding if there is RCD protection.

why have you posted something that is outdated and irrelevant?
do you know what resistance from MET to pipework is permitted to be under without bonding?
I think the handyman in the title gives it away,
I still think any decent plumber would leave a copper tail after the stopcock to bond to.

do you know that water is a very poor conductor,
yes, of course you do, you have stated a number you have found on the internet.
do you know why we bond peoples water pipes?
its the additives that the water companies put in it that makes it conductive, and not only the copper,
so you obviously know exactly the composition of the water in the OPs house and its resistance then.
and you can obviously fill in a test cert for OPs house stating your deviation and the rest of the resistance readings to back up this non compliance.
do you want a job working for me?
