6mm water bonding on PME

[TheCodboy]

Hi all, I imagine that this has been asked a few times, but here goes. A customer who is selling their house has been on looking to change the consumer unit. Getting to the gas isnt a problem but the water is impossible without desctruction of some sort. Concrete floors, and the stopcock is on the other side of the house to the CU, and its also on the adjoining side of next door. Now as i would class this as alteration, i think that reg 132.16 covers me not to touch it, if there are no signs of deteriation and i have a continuity reading. What do you guys say?

if there's no sign of thermal damage, you can leave as is, but add a comment on cert. you may find that the water is bonded to the gas at the boiler anyway.

Would you write it in departures and quote the reg number??

If you can quote a regulation number then that suggests it is not a departure.

So how would you go about making a note in the cert? I see where your coming from,as you say there’s a reg to cover it so technically it’s not a departure.

I would record the size of the main bonding in the box on the details of the supply page where it asks for the size of the main bonding.

Thanks for the info!!

If the water main is PVC, it doesnt need bonding!

PS It always amazes me this, why do people who are selling a property think that they have to change the consumer unit?

And if the water pipe does not become extraneous on the consumers side by making contact with the ground at any point.

Plus of course water mains arent normally PVC at all, they are made from MDPE these days.

So is this where I would IR test it to see if it’s extraneous?

It is where you would carry out a test to establish whether or not it is extraneous, but it is not strictly speaking a test of insulation though it can be carried out using the same settings on the tester.

I’ve never seen anyone ever carry this out. The only reason I know of it is from this forum!

I've never seen someone carry it out either, but that doesn't really have any bearing on it.

You'd probably have to shadow a domestic electrician every day for months on end watching them before you saw them test something to see if it is extraneous.

Yes. Should have just said “plastic stuff”.
