I have had a problem with an electrical charge (tingling on touching taps and hand shower rail).
The intensity varies but I can not find a pattern (time of day, rain etc.) Last night there was an actual "flash" from the shower head while taking a shower.
The geyser is a solar installed on an IBR roof. Installation was done by a reputed company.
I have a 1m copper earth installed at the entry point of the water pipe to the house
The pipes in the house are galvanized (old) and copper (solar geyser)
Various electricians have all not been able to come up with a solution.
I would like a reference to an electrician/plumber in the Pretoria area with proven experience in this type of problem please.
