We’re OnCall Emergency Plumbers, Melbourne-based and available 24/7. If you face a no hot water emergency, we’ll explain quick checks and when to call us so you can get a practical solution fast.
Having no hot water disrupts daily life in your home and on your property. The RTA treats this as an emergency repair, with an expectation that work begins within 24–48 hours. That means owners, agents and tenants should act quickly.
We prioritize safety, fast diagnostics and clear communication. Our licensed team uses quality materials from reputable brands to fix the water system and reduce repeat problems. If parts or owner approval are needed, we’ll explain the timeframes and keep you updated.
Start by isolating utilities if you suspect a leak, prepare access and tell us about any prior issues. Call your property manager by phone and follow up in writing to document the problem and time expectations. For immediate help across homes and properties, call 1800 571 216.

Immediate steps in a no hot water emergency
Immediate, safe action helps limit damage and speed up repairs to your hot water system. Follow these checks before we arrive so our service starts on time and with the right parts.
Stay safe first
If you smell gas or see electrical sparks near the heater, isolate power at the switchboard and shut off gas at the meter or bottle if safe to do so. Step back and call us for urgent advice.
Quick checks to run
- Confirm the hot water breaker or fuse hasn’t tripped and off‑peak timers are active.
- For gas systems, check the gas supply, bottle level and pilot light per the manufacturer’s guide.
- Run multiple taps to rule out a single‑tap fault; low flow at one outlet often means a mixer or aerator issue.
Prepare for rapid service
Unlock gates, clear access to the unit, and secure pets. Take photos of error lights, leaks or stains and call 1800 571 216 for 24/7 assistance across Melbourne.
| Check | Action | Why it matters | Likely cause |
|---|---|---|---|
| Breaker/fuse | Reset or note tripped | Tells us if circuit fault exists | Electrical fault or timer |
| Gas supply | Confirm bottle or meter | Confirms fuel for burner | Empty bottle or interrupted supply |
| Multiple taps | Run and compare flow | Distinguishes system vs fixture | Isolated valve or aerator |
Quick troubleshooting for common hot water system problems
Short, safe inspections at the outlet and control panel reveal many common heater issues. We recommend a quick check before we attend so our licensed team can diagnose faster and bring the right parts.
No hot water at all: thermostat, element or tripped circuit
We check the breaker, fuses and timers, test thermostats and elements on electric units, and inspect ignition and burners on gas systems. We test components safely and advise repair or replacement.
Inconsistent water temperature: tempering valve and mixing issues
Faulty tempering valves or mixer faults cause uneven temperature. We measure outlet temperature, inspect the valve and clean or replace worn parts to restore safe, steady output.
Low hot water pressure: valves, filters and hidden leaks
Low pressure often comes from closed isolation valves, blocked filters or scale. We check static and running pressure, clear restrictions and trace any hidden leak in pipes or fittings.
| Symptom | Likely cause | Action we take | Outcome |
|---|---|---|---|
| Rumbling tank | Sediment build‑up | Flush tank, check anode | Quieter, longer life |
| Pooling beneath unit | TPR valve or corroded tank | Test valve, inspect joints | Repair or advise replacement |
| Gas odour or burner fault | Leak or ignition issue | Shut gas, inspect burners | Safe operation restored |
Where parts are needed, we carry quality components from reputable brands to reduce repeat faults. For an experienced local response, see our page on hot water repairs in Black Rock.

Approvals, quotes and keeping things moving
For higher‑value works, owners often need quotes and approvals before we replace hot units or tanks. If costs exceed statutory thresholds, the approval process can extend time to repair by a few days.
We speed decisions by supplying clear findings, photos and itemised quotes so owners and managers can approve repairs quickly. We coordinate with strata and portfolio managers to limit disruption and keep documentation for audit trails.
