Common Hot Water Repairs We Handle
No hot water, water that won’t stay hot, a leaking tank, a pilot light that won’t stay lit, unusual noises from the unit, or inconsistent temperature are the faults we see most often on hot water repairs Sydney-wide. Most calls are diagnosed and quoted on the spot, with many repairs completed same visit using genuine parts.
Keeping Your Hot Water System Running
A few simple habits extend the life of any hot water system and reduce the chance of an unexpected breakdown. Annual servicing lets a licensed technician check the anode, pressure relief valve and thermostat before small issues become expensive ones.
This is especially important for gas systems, where a poorly maintained unit can also raise safety concerns. Storage tank systems typically last 8 to 12 years depending on water quality and usage, while continuous flow units can run longer with regular servicing.
If your hot water system is over a decade old and starting to make noise, run out of hot water faster than it used to, or show rust-coloured water, it’s worth having it inspected rather than waiting for a full failure.
