Start with the system and fault history
Send a clear photo of the unit label and describe leaks, noises, performance or the replacement you are considering. Do not open gas or electrical components yourself.
For gas work, check the gasfitting authorisation; electrical work may also need a licensed electrician. Ask the business how it will coordinate trades and required paperwork.
Compare the complete hot-water price
Ask about diagnosis fees, repair parts or replacement unit, capacity, valves, pipe changes, electrical or gas work, removal of the old unit, compliance records, warranty and GST.
Good questions. Plain answers.
Can a plumber fix an electric hot-water unit?
A plumber can handle plumbing tasks, while electrical tasks need the properly authorised trade. Confirm who will do each part.
What if I do not have hot water right now?
Use the no-hot-water problem page for first-contact and safety guidance.
