Electric Sink !!!!!

[eskimo39]

A friend asked me to go around to his house as his wife kept getting shocks whilst washing up. I used my Fluke T5 and used the earth from a socket and then touched the sink...... I got 115v.

I then scratched a bit of paint from the washer and when tested also got 115v?? The same result with the waterpipes.

I isolated the circuits one at a time and found he fault occured when the downstairs ring main was on, so assumed that a wire must be bare and touching a water pipe, however I have looked everywhere and cannot find a wire with any signs of obvious damage.

Can anyone else spread some light on what could be causing this?

It was quite dark when I went around so didn't get down in the cellar to check the CU and bonding but could this have something to do with it?

Thanks in advance

Have you unplugged all the appliances on the circuit and isolated any fused outlets? it may be a faulty appliance.

Yes definitely check earthing and bonding, including MET do a Zs test.

Do all the usual tests and inspections.

If its any consolation i once had a similar problem with a lighting circuit and i ended up rewiring it.
