No Hot Water — And No Idea What's Actually Wrong?
When your hot water stops working, most people assume the worst and brace for a big bill. The reality is that a lot of hot water failures come down to a single faulty component — a worn heating element, a failed thermostat, a corroded anode rod, or a pressure relief valve that needs attention.
The other problem is getting the runaround. You call someone, leave a message, wait for a callback, and by the time you speak to a person — if you speak to a person at all — you still don't know what's wrong or what it's going to cost.
Meanwhile the hot water is still off, and you're making decisions blind. It doesn't have to be that way.
Call NowHow We Approach Hot Water Repairs
When we arrive, we don't just look at the obvious. We test the heating element, check the thermostat, inspect the pressure relief valve, assess the anode rod, and check all connections. The goal is to find the actual cause — not just what's visible on the surface.
The most frequent repairs we see are heating element replacements in electric systems, thermostat faults causing lukewarm or quickly-exhausted water, and pressure relief valves leaking or releasing regularly. We also repair gas burner and ignition faults, replace anode rods, and fix leaks at fittings and connections.
If the repair makes sense, we get on with it. If the cost of repair is close to a new system — or the unit is old enough that further faults are likely — we tell you clearly and walk you through replacement options. You can read more about our hot water system replacement service here.

Frequently Asked Questions
Not necessarily. Many hot water failures are caused by a single faulty component — a heating element, thermostat, or pressure relief valve. We assess the full system before making any recommendation. If a repair makes sense, that is what we will suggest.
The main factors are the age of the system and the cost of the repair relative to replacement. If the unit is under ten years old and the fault is a single replaceable part, a repair almost always makes sense. We give you an honest breakdown so you can make the right call.
For common faults like heating elements and thermostats, same-day repairs are usually possible. We carry commonly needed parts and can often attend and complete the repair in one visit. Call us and we will let you know based on current availability.
A dripping pressure relief valve usually means either the valve itself has failed or the system pressure is too high. It should be checked promptly — left alone, excessive pressure can cause more serious damage to the tank. We test both the valve and the system pressure when we attend.
This is often a sign of a failing heating element or a thermostat that is not maintaining temperature correctly. It can also indicate sediment build-up in the tank reducing its effective capacity. We check the full system to find the cause.
Yes. We repair electric storage systems, gas storage systems, continuous flow units, and heat pump systems. All gas repair work is completed by a licensed gasfitter.
We service Sunbury and the surrounding north west suburbs of Melbourne, including Diggers Rest, Bulla, Gisborne, Riddells Creek, Lancefield, and Macedon. Call us to confirm availability for your location.
