The Hot Water Problems We Repair

Gas and electric tanks and continuous flow units, found and fixed at a price agreed before any work starts.

No Hot Water

Cold from every tap. We find out whether it is the power, the gas, an element, a thermostat or a continuous flow unit showing an error code, and get it heating again.

Leaking Hot Water Systems

A drip from a fitting or valve on top is usually a repair. Water coming out of the tank itself means it has rusted through and needs replacing with a new system.

Dripping Relief Valves

The relief valve lets out a little water while the tank heats. A constant drip or a steady run from its drain pipe means the valve is worn, so we replace it and test it.

Elements And Thermostats

An electric hot water system that has stopped heating, or only heats a little, usually has a failed element or thermostat.

Low Hot Water Pressure

Hot taps that barely run while the cold is fine, usually a blocked filter or a faulty valve where the water goes into the system.

How Bad Is Your Hot Water Problem?

Water Pouring From The Tank

Water running out of the tank or pooling around it will not stop on its own. Turn off the cold water valve going into the system, switch off the power or gas to it, and call us.

No Hot Water At All

Check that the hot water switch or circuit breaker is on for an electric system, or that the gas is on for a gas one. If the water is still cold, book a repair and we will find the fault.

Lukewarm Or Running Out

Showers that go cold halfway through, or water that never gets properly hot, usually mean a worn element, thermostat or tempering valve. It will not damage anything, so book it in.

Hot Water System Repairs FAQs

Answer:

It depends on the fault and the part: a relief valve or thermostat is a smaller job than a gas valve or a continuous flow unit's circuit board. We find the fault first, then give you one fixed price to approve before any work starts. There is nothing to pay just for us to come and look during business hours.

Answer:

You can check the basics: that the switch or circuit breaker is on for an electric system, that the gas is on for a gas one, and whether a continuous flow unit is showing an error code. Replacing valves, elements, thermostats or gas parts is licensed work. Never block or cap the relief valve or its drain pipe.

Answer:

On an electric tank the usual causes are a tripped circuit breaker, a failed element or a faulty thermostat. On a gas system it is often the pilot, the igniter, the gas valve or the gas supply, and a continuous flow unit usually shows an error code. We test each part and tell you what has failed before anything is replaced.

Answer:

A little water from the relief valve drain pipe while the tank heats can be normal. A steady run from that valve, a drip from a fitting, or water pooling under the tank is not. Valves and fittings can usually be repaired, but a leak from the tank itself means it has rusted through and needs replacing.

Answer:

Repair makes sense when the tank is sound and the fault is a valve, element, thermostat or igniter. Once the tank is leaking or badly rusted, or the system keeps breaking down, a replacement is the better use of your money. We tell you which on the spot, with a fixed price for either.

Answer:

A worn element or thermostat can leave the tank only partly heated, and a faulty tempering valve can let too much cold water into the mix. Sometimes the system is simply too small for the household. We check which it is before recommending a repair or a bigger system.

Answer:

New hot water installations in NSW must limit the water going to bathrooms to 50 degrees, and a tempering valve does that job. When it wears, the basin can run scalding hot or the shower never warms up properly. We service or replace the valve and check the temperature at the taps.

Answer:

Discoloured hot water usually means rust inside the tank, a worn anode, or sediment that has built up over the years. If the cold water is clear and only the hot is discoloured, the hot water system is the likely cause, so book a check before the tank starts to leak.

Answer:

Yes. We repair all the major brands, including Rheem, Rinnai, Dux, Thermann, Bosch, Vulcan and Aquamax, in gas and electric storage tanks and continuous flow units.
