General guidance, not an inspection or diagnosis. Repair advice has not been independently reviewed by a tradesperson. About this checker and safety sources.
What to do now
If you smell gas, hear hissing, see leaking near electrical components or the unit is overheating, keep clear and arrange urgent licensed help.
Common causes
- Failed heating element or thermostat
- Gas ignition or supply fault
- Pressure / tempering valve issue
- Ageing or leaking storage tank
The exact cause cannot be confirmed from a symptom alone. The first professional should inspect before repair work is authorised.
What usually happens next
- Identify system type and age
- Check for visible leaks or fault codes
- Test heating and safety components
- Repair or compare replacement cost
What should I ask about the price?
Ask for an itemised quote covering the inspection or call-out fee, labour, materials, GST, access, disposal and any after-hours charge. Ask what happens if extra damage is found. A reliable price needs details of the actual job; this guide does not provide an estimate.
Who may be responsible?
Owner / landlord
In a rental, loss of hot water can require prompt landlord/property-manager action. Emergency rules vary by state.
Tenancy, strata, insurance and boundary responsibilities vary by circumstance and state, so confirm responsibility before non-emergency work where practical.
Questions to ask before hiring
- Are you appropriately licensed or registered for this work in my state?
- Does the quote include call-out, labour, parts/materials, GST and disposal?
- What is excluded from the quoted scope?
- If you find additional damage, will you get approval before doing extra work?
- What workmanship or product warranty applies?
