Our plumbers in Templestowe have been serving residents of north-east Melbourne for close to 20 years now. During that time, we’ve helped local families with all their plumbing needs – oftentimes, that includes issues with their hot water systems.

There are a lot of problems that can occur with your hot water system – in many cases, it’s the most mechanically complex part of your home plumbing… not to mention, one of the most dangerous!

That’s why it’s so important to always call a professional if you think you’re hot water system is experiencing issues.

We know it’s tempting to bring up a YouTube tutorial, break out the tools and try and fix it yourself. If you ask us however, it’s simply not worth it in the long run.

A plumber in Templestowe explains why DIY should be avoided


As we mentioned above, in most cases the hot water system is one of the most complicated parts of your home’s plumbing system. Unlike often simpler tasks like unblocking a toilet, there’s a lot of scope for a misdiagnosis if you try fixing it on your own.

For example, can you…

  • Tell the difference between a faulty thermocouple, gas control or heating element?
  • Repair and replace valves on your own?
  • Understand how thermal expansion can damage your hot water system?

Unless you can answer “yes” to each of these questions (and you happen to hold a plumbing license of your own), we strongly advise against trying to diagnose your hot water problems!

If you misdiagnose the problem you could end up creating an unsafe situation and potentially causing more damage resulting in spending even more money to get it fixed.

Can you guarantee that you have the right parts?

Your Templestowe plumber has an entire storage facility, full of plumbing components, including parts that go into hot water systems. And even if they don’t, they’ll be able to order the proper component quickly thanks to their relationships with suppliers.

A DIY plumber on the other hand doesn’t benefit from this.

Even if you do correctly diagnose the issue, you may be forced to order cheap parts off Ebay or Amazon. While they may work in the short-term (again, assuming you get the installation right at all), they’re simply not as good.

The result? Your hot water system failing again, and much sooner!

You might simply get it wrong

Let’s just say there’s a reason that we plumbers need to complete a Certificate as well as a mandatory 4-year apprenticeship before we can start working on our own!

There’s a lot of training that goes into becoming a plumber – we need to learn about things like:

  • Water pressure
  • Air pressure
  • Drainage systems
  • Different piping materials
  • Proper sanitation
  • Gas piping

Each of these factors come into play when talking about your hot water system. Unless you’re trained in each of these, we advise against trying to fix things on your own.

Insurance problems

As any homeowner knows, water damage can result in much of your house (as well as everything inside) being damaged.

In many cases, you’ll have to file an insurance claim to cover part of the cost of getting everything restored and fixed.

Here’s the thing, though: very few, if any insurance policies will cover complications from a poorly executed DIY job.

If the cause of the problem was a dodgy DIY fix for your hot water system however, you can say goodbye to that insurance payout – just another reason to avoid DIY hot water plumbing!

Our emergency plumber explains possible problems with your hot water unit

Our plumbers in Templestowe are going to run you through the main cause of issues with your hot water system.

Just remember that just because you’ve read this blog post doesn’t mean you are an expert – don’t take this as an excuse to try fixing things on your own!

We simply want to help you have a better understanding of what might be happening so you can let us know when you call our emergency plumbers to come and fix the problem for you.


In our experience, leaks are the most common cause of hot water problems.

Whether it’s the thermal expansion chamber, an inlet valve or a water supply pipe, there are many points where a leak might spring in your hot water system.

Luckily, it’s pretty obvious when your hot water system starts leaking. 

You will consistently find water pooling around your hot water system – in particularly bad cases, you may even experience flooding. 

We often see people assuming that its the pressure relief valve creating the leak. They replace it and very often still experience the same problems.

To ensure that the actual source of the leak is identified and fixed, you’ll need to talk to a plumber in Templestowe.

 A busted circuit breaker

Circuit breakers are attached to almost every electrical system there is. They’re an essential part of electrical safety, cutting off power in the event that a power surge is detected.

So, if your hot water system is heated electrically, your circuit breaker could be playing a part in your hot water problems.

A circuit breaker stops wires from overheating and causing fire hazards. 

If your wiring overheats then the circuit breaker will trigger and stop electricity from flowing through your wire. If this happens, it will stop your hot water system from functioning. 

Remember though – even if you are sure it’s your circuit breaker that is the problem, there are still multiple reasons you could have tripped it. 

It’s best that you get in contact with local plumbers in Templestowe in order to make sure the problem doesn’t keep occurring.

And if worse comes to worst, you may even need an emergency electrician on your side too!

Tempering valve

Your tempering valve is designed to regulate the temperature of your water.

It combines hot and cold water to remove the risk of burns when water comes out of the tap.

Most tank hot water systems maintain water at a temperature of 70ºC. At this temperature, you may receive a burn after a mere second of direct exposure.

At 50ºC degrees however, you would need to hold your skin under the water for several minutes until the water starts burning you.

Needless to say, this humble valve plays an important role in keeping your family safe!

If you find that your hot water is unbearably hot when it comes out of the tap, you need to call our plumbers in Templestowe ASAP – something’s wrong with your hot water system. 

An emergency plumber will be able to locate and replace the faulty valve in question, allowing you to enjoy hot water without the risk of scalding yourself.
