December 17, 2025

If you’ve ever got into a shower with no hot water, you know that sinking feeling. It’s the kind of thing that makes your day start off on the wrong foot. I’ve been there, and I’ve also seen countless homes in Highton and Geelong West struggle with hot water issues simply because their systems weren’t looked after.

Answers to your most frequent hot water questions.

Give Your System Some TLC

Let’s start with the obvious: maintenance.

I know, I know, it’s not the most exciting topic. But trust me on this one.

I had a mate in Geelong West whose gas hot water system was pushing 12 years old. No services. No flushing. Nothing. When I checked it out, the tank was packed with mineral build-up. It was basically working overtime just to heat water. After a proper flush and a general service, it was like night and day. The system ran smoother, heated faster, and stopped making those weird noises.

Can you imagine that relief? No more cold showers. No more stressing about the system giving up at midnight when you’ve got work the next morning. That feeling alone made it worth it.

Tip:
Flush your gas hot water system at least once a year. This clears out sediment that slowly corrodes the tank from the inside. Think of it like cleaning your coffee machine. If you don’t, the build-up ruins the taste, and eventually the machine. Same idea here. Clean system, happy system.

Watch the Pressure

Now, let’s talk about water pressure, the silent troublemaker.

High pressure is like sending your hot water system to the gym and telling it to run a marathon every single day. Sure, it might cope for a while. But eventually? Something gives. I’ve seen systems leak, crack, or completely fail just because the pressure was constantly too high.

The scary part? Most people don’t even realise it’s happening.

Tip:
Aim to keep your water pressure around 50–60 psi. Check your pressure gauge now and then. If it’s running high, don’t ignore it. A plumber can adjust it quickly, and it can save you a lot of money and stress later. Simple fix. Big impact.

The Magic of the Anode Rod

Here’s a little secret most people don’t know about, the anode rod.

This thing is basically your tank’s superhero. Its entire job is to attract corrosion so the tank itself doesn’t rust. Sounds clever, right? The problem is, once the rod is worn out, the tank becomes the next target.

I once worked on a system that easily lasted five extra years just because the anode rod was replaced in time. Five years! That’s not luck, that’s smart maintenance.

Tip:
Check the anode rod every two to three years. If it’s heavily worn, replace it. It’s like giving your hot water system a shield. Ignore it, and the tank cops the damage instead.

Smart Hot Water Habits

This reminds me of a client in Highton. Her hot water temperature was cranked way up, way more than it needed to be. The system was constantly reheating, working harder than necessary, and honestly it was struggling.

That’s when it really hit me, daily habits matter more than people think.

Tip:
Keep showers reasonable, fix dripping taps straight away, and set your hot water temperature to around 60°C. Too hot, and you’re stressing the tank. Too cold, and you risk bacteria. It’s all about balance — and your system will thank you for it.

Keep the Area Clear

This one seems small, but it’s huge.

A cluttered hot water system area is a recipe for missed leaks and delayed repairs. I once tried to inspect a tank that had boxes, paint tins, and random junk stacked all around it. Total nightmare. If there was a leak, no one would’ve noticed until it was too late.

Tip:
Keep 30–50 cm of clear space around your system. That way, you can spot issues early, and servicing becomes quicker and safer. Plus, it just makes life easier all round.

Watch Out for Rust and Leaks

Even tiny problems can turn into expensive ones if you ignore them.

I remember spotting a small drip on a system in Geelong West. Barely noticeable. The homeowner thought it was no big deal and left it for weeks. That tiny leak ended up damaging the tank, and the whole system had to be replaced. Painful lesson.

Tip:
Check your system every few months. Look for rust, damp patches, water stains, or dripping connections. If something feels off, trust your gut and call a plumber straight away. Early fixes save big money later.

Energy Efficiency Matters

Here’s the thing, an overworked system doesn’t just wear out faster. It costs more to run.

I once had a family in Highton who couldn’t understand why their gas bills were climbing. After a quick inspection, it was clear their system was constantly reheating water because of sediment build-up and incorrect temperature settings. A flush and a small adjustment later? Lower bills and a happier system.

Tip:
Proper maintenance plus the right temperature equals a long-lasting, efficient hot water system. Think of it like feeding your body the right food. Treat it well, and it performs better for longer.
