Pricing help on kitchen refit

[pc1966]

The only extra which I found out today is the water stop tap has been moved by the plumber, who removed the bonding and has left cut off (the homeowners are still living in the property). Have told the builder I will need to run a new 10mm bonding from the CU to which he said just crimp the existing one to make it reach ?

Not a good approach to change it without doing the cable there & then, unless of course the external pipe is now plastic.

A proper crimp is OK, can be tidied with some heat-shrink sleeving if needed, but I shudder to think that your typical plumber would do.

Is is not against regs though? The same as if gas and water was on the same bond you have to just take off the insulation at the first point and not break the cable in case it comes loose?

With kitchens: only give a fixed price when you have a complete and confirmed kitchen plan with full details of all appliances.
If anything changes from that point (and it will) it is EXTRA!!

No.
And it's a myth that a single cable used to bond both gas and water services needs to be continuous and not broken.

There is nothing in the regs that say you must have a continuous length. But the example on GN3 (I think) shows what you suggest as good practice to avoid one fault causing multiple trouble.

I would say (don't think it is explicit in the regs though?) that any joint must be reliable / maintenance-free. You would get that from a solder joint, a proper crimp, or using an approved type of joint & enclosure.

Just looked, it is GN8 on page 64 (Figure 5.5 an unbroken protective bonding conductor).

But I would argue that a permanent joint is "unbroken".

And if labelled correctly per 514.13.1 it should never become a problem ........ just a shame some take no notice of it!

Here's one way of looping a 25mm2 bonding conductor from gas pipe to water pipe - the wrong way.

 

[Taylortwocities]

25mm? Really?

Current board is a dual RCD Wylex so no need to change anything there just add a couple of breakers for the cooker circuits.

Bear in mind that the total of the MCBs hanging off each RCD should no longer exceed it's rating (unless main fuse is <or= to them) also you'll need to notify your 2 new cooker circuits and fill EIC.
