Earth continuity on bathroom rad

[Mdljk]

Hello

Had to install a new towel rad in bathroom. Replacement narrower than original so had to adjust 10mm pipework. On breaking into stud wall I found that the green/yellow earth wire clamped to the rad pipe was chopped off and merely plastered over in the stud wall. Property 20 yrs old and clearly the way the builders electrician had left it. Bathroom floor tiled. No pipework to extend/reattach loose end to without lifting chipboard in adjoining bedroom and breaking into back of stud wall from there.

I can’t imagine I’m the first to experience this issue but what is the usual course of action?

Supplementary bonding. Is the incoming metallic pipe extraneous? Does the bathroom have RCD protection for low voltage circuits serving that location?

Have you tested the need for bonding?

Have you tested the need for bonding?

Tend to agree with you there Mate.

Tend to agree with you there Mate.

Agreeing with oneself, must be against forum rules.

Thanks for the replies. Looked at DB - upstairs sockets on RCD, upstairs lights are not.

As regarding testing the NEED for - I don’t know how to do this. There is a clamp and earth cable to the domestic hot water pipe behind yhe bath but the broken wire was clamoed to the heating pipework. Is testing if it NEEDS earthing something only a qualified electrician can do?
Thank you

The pipe with the clamp on is the heating flow pipe so not extraneous.

There is no low voltage circuit (shaving socket?) in the bathroom.

@Mdljk in the past anything metallic, certainly in a bathroom would of been bonded (earthed in some parlance). Some might say that new towel radiator metallic pipe work needs re-bonding. Only way to tell is have an electrician test it to see if its extraneous (you can google that).

Thousands of bathrooms have been refurbished in the last few years to a similar standard, to no detrimental effect, who should say it must be.

Thanks Midwest. I’ll get on to that.

Have googled this and am reassured by the following :

Under the 17th edition regulations, supplementary bonding in the bathroom is not required provided that;
all electrical equipment in the bathroom(light, extractor fan, electric shower, etc) are RCD protected and that the main protective earth bonding is in place.

My bathroom has an outside light switch on the landing the fan is installed in the loft by a duct and I have zero electrical fittings other than the downlighters that are correctly zoned.

Midwest you helped with the two key words ‘supplementary’ and ‘extraneous’. Researching these terms helped me greatly. Thank you.
