Is Your hot water system on its last legs? Here’s how to tell

Your hot water system is one of those things you don’t think about—until it stops working. No one wants to wake up to a cold shower or deal with unexpected plumbing issues, but knowing the warning signs early can save you from a major headache (and an emergency plumbing call-out).

As trusted Adelaide plumbing experts, we’ve seen it all—so here are 5 key signs your hot water system might need replacing.

1. Your water isn’t hot enough (or it runs out too quickly)

If your hot water system isn’t heating properly or you’re running out of hot water too soon, it could be struggling to keep up. Sediment buildup, aging heating elements, or a failing thermostat are common plumbing issues that signal it’s time for a replacement.

2. Strange noises coming from your system

Gurgling, banging, or rumbling sounds coming from your hot water system aren’t normal. These noises often mean there’s sediment buildup in the tank, causing it to overheat and work harder than it should. Ignoring these sounds can lead to bigger plumbing issues down the track.

3. Leaks or rust around the unit

Noticing water pooling around your hot water system? Leaks, corrosion, or rust can indicate serious internal damage. A small leak today can turn into a big problem fast—leading to costly repairs and potential emergency plumbing situations.

4. Water discolouration or bad smells

If your hot water is looking rusty, muddy, or has a metallic smell, your hot water system could be corroding from the inside. This isn’t just bad for your plumbing—it can also affect your water quality and lead to further plumbing issues.

5. Your system is more than 10 years old

Most hot water systems last between 8-12 years. If yours is over a decade old and showing any of the above signs, it’s best to replace it before it completely breaks down—saving you from an emergency plumbing situation.
