Fault-finding 🇦🇺 WA / AustraliaWhy do I get a tingle from a tap or the shower?
Here are the usual causes, most likely first, and how an electrician would track it down.
Likely causes
- Missing or broken bonding
- Earth fault on an appliance (immersion, pump, washing machine)
- Lost supply neutral on MEN raising earth voltage
How you'd find it
- Treat as dangerous – stop using the taps
- Check main bonding is in place and tight
- IR test circuits/appliances on the plumbing; measure voltage between the pipe and earth
Usual fix
Fix the faulty appliance/wiring; restore bonding. A suspected supply neutral fault – call Western Power urgently.
⚠️ Safety: Stop and safely isolate before touching anything. If you're not qualified, leave it to a licensed electrician (WA licence).
Regulation: AS/NZS 3000:2018 (protective bonding).
Study aid in plain English, not the text of the standard. Always check the current AS/NZS 3000:2018 + WA rules and your local rules. Electrical work must be done by a licensed or registered electrician.
