I had a call a few weeks ago where the customer said he'd been taking
meter readings and he was losing about £10 of electricity a day. He
thought it was something to do with his boiler as sometimes he had some
warm water coming out of the cold tap. Sounded like a sensible bloke,
even though what he was saying was a bit odd, so I went for a look.

Supply was nominally a TT (no sign of a rod) with an old Wylex
rewireable box. Clamp meter on + tail 10.5A, clamp meter on - tail
0.5A. Pulled the fuses an found the current was flowing in the ring. A
quick look around found a socket with a very hot screw - the live had
been nicked by the screw and was providing a nice 24 ohm earth path to
the incoming lead water main. An expensive way to heat the water in the
first few feet of lead pipe and lucky not to have had a fire.


Seems to me the kind of thing most people would be more likely to spot
with a smart meter and a free display of their current [sic] consumption
