Hi Guys. After a bit of advice. I've heard about the following happening before but not come across it myself.
I carried out an EICR this morning on a barn conversion. TT earth. All main bonding in place, Oil and water although both appear to be plastic. 30m/a front end RCD. RCD trip times are satisfactory. Earth spike reading was just over 34ohms. Lots of supplementary bonding throughout as well.
Female tenant gets occasional shocks off kitchen taps and shower (mixer taps not electric). She says it only happens if she has a cut on her fingers (not sure how you regularly get a cut on your finger but that's what she said).
Nobody else in the property gets any shocks .
Both are on the ground floor. Kitchen floor is flagstones. Bathroom floor is a wooden floor, shower is in a cubical, don't know what the ceramic tray is sat on.
I have taken an earth continuity reading from a socket to the kitchen tap pipework and am getting about 20 ohms. I don't know how accurate that is as the pipes are extremely difficult to access and appear to be painted. I cleaned them up as best I could but am literally only able to get the end of a tester prong on to it at a stretch as everything is behind the kitchen units. The taps are connected with flexi hoses.
I did the same test to the shower mixer and got just under 0.3 ohms. Again difficult getting a decent connection with my probe.
Some advice on the best way to proceed would be appreciated. Is there a better way to test this? Not sure what the solution is if there is an issue as bonding is already there.
