I have recently moved into a studio barn converstion and some parts have not been wired professional. All seemed fine but recently we have recieved minor shocks from the copper water piping in the bathroom, the sink, the hob and the oven which is worrying to say the least. I don't think everything has been earthed corrently? Could this be the cause of the problem or does the fact their is a current passing through signify something more serious. Most importantly is this really dangerious or just a somewhat dangerous? I know we need to have a professional out to look at this but if anyone could give me any indicators of what the problem may be that would be great. Thanks Aaron.
The fact that you are getting shocks off the pipe work, sink etc.. suggest that it has been earth bonded coorectly. that's the good news!
But you have a fault with your electrics that is why you are recieving a shock and it needs to be addressed straight away. A live conductor is putting voltage in to your earth bonding to find earth.
Get the electrician around ASAP!
We had a similar experience next door to us some years ago when the occupants were getting slight shocks from metalwork -- it turned out that they had a fault on their washing machine which was making their pipe-work live, as the water system had a section of plastic pipe inserted, the complete system was not properly connected to earth. Also they discovered that the ECB in their electrical system was not properly installed.
Hope this helps to sort out your problem, if not already solved!
P.S.: Also, at that time, the mains water feed in the street was ALL PLASTIC (not compatible to good earthing!) and the stop-tap in the street outside their gateway was occasionally live.
