Might seem an odd question, but I'm fitting a new kitchen at the moment, and have discovered beneath the old sink that:
a) the mains earth is connected to the cold water pipe (feeding directly into the ground);
b) there's an earth wire running from the cold water pipe to the hot water pipe; and
c) there's another earth wire running from the hot water pipe to a clamp beneath the sink.
I'd have thought just a) was OK; but I'm checking here because this has me both confused and slightly worried. Do I just need to connect the earth wire(s) to the cold water, or to the hot and/or sink as well?
Cheers.
