Outside tap

[timboy]

Many years ago I had an outside tap fitted. The plumber cut into the cold water pipe to my sink, put the pipe through the wall and fitted the tap. Never any problems until I got a landscaping firm in to alter my back garden. They tell me that when they touch the top of the brass outside tap they get a tingle in their fingers. I have never experienced this and nobody else ha until now. Anybody had the same thing, or can tell me what it may be, or even what to do to stop this happening? I did have a water softener fitted, connected to the coppe pipe under my sink and the softener is plugged into the electricity as instructed by the maker. Maybe it is the electricity from this affecting my tap. I have not got a clue.

Im not an electrian but maybe that the brass tap requires an earth wire or the copper pipe it runs to under the sink requires earthing.
Fast running water also generates static electricity which can build up to give quite a shock.

You really need to get this checked out by an electrician.

The old way to earth wiring in houses was to clamp on to a water pipe, they were always made of copper iron or lead so conducted away any leaks to ground but nowadays they use non conductive plastic pipe and if someone's added a bit of that and broken the circuit you could be at risk of electrocution.
