This has got me stumped,continuos corrosion on a water pipe,plumber claims hes getting zapped,well we checked the supply right back to the transformer,everything ok,with neutral disconnected from earth -15 vdc appears enough to light 400 watts worth of 12 volt lamps,PEX installed from street to water meter just below electric box everything ok now I suspect a railway line at the back of the house has broken traction bonds on their 1500vdc system,what do you guys think.Circus Rail,sorry City Rail says not me,but the problem only started after 2 extra tracks for freight trains were added.The woman is going mad listening to autocouplers bang and crash and wheels squealing all the time.
