Why does the hot water run out faster than it used to?
Sediment in the bottom of the cylinder, a failing element, or simply more demand on the same system than it was sized for. A mixing valve letting cold through can produce the same complaint.

What Is Involved
Hot Water Repairs help in Thornlie
Hot water problems are diagnosed from the symptom backwards. No hot water at all, hot water that runs out early and hot water that swings temperature are three different faults with three different fixes, so MLC Plumbing checks the unit, the valves, the supply and the tempering before recommending anything.
Thornlie properties often combine established plumbing, busy family bathrooms and rental maintenance needs. That means small faults can become costly if they are left too long, especially dripping taps, running toilets and slow drains. Locally that means busy family bathrooms and rental fixtures make early repairs worthwhile before small faults become disruptive.
The same job across the rest of the service area is covered on our hot water systems page, including what a visit involves and what it usually costs.
Signs your hot water needs attention
- Unusual noises, banging or pressure changes
- Temperature swinging hot and cold at the same tap
- Water dripping steadily from the relief valve
- The unit is more than ten years old and starting to be unreliable
Common hot water faults
- Failed valves, elements, thermostats or burners
- An ageing storage cylinder beginning to leak or corrode
- A system undersized for how much the household now uses
- Sediment build-up reducing how much usable hot water is left

Good to Know
Hot Water Repairs questions, answered
Do you work on gas and electric systems?
Both, plus solar and heat pump. The gas side is carried out under gas fitting licence GF 18736 and the plumbing under PL 11420, which is why one visit can cover the whole job.
Can you fix water that keeps changing temperature?
Often. It can be a tempering or mixing valve, a thermostat, a partly blocked fixture, or a unit that is struggling. The same symptom has several possible causes, so it gets checked properly rather than guessed.
Which parts of Thornlie do you work in?
All of it — including near Thornlie Square, Spencer Road and the established streets toward Yale Road. If you are unsure whether your street is covered, ring 0448 471 377 and you will be told straight away rather than sold a call-out.
