Signs Your Gas Hot Water Heater is on the Brink of Breaking Down

Al Mclean • August 17, 2025

As the scorching Australian summer approaches, many of us are eagerly preparing for outdoor gatherings, barbecues, and pool parties. However, one aspect of preparation that often gets overlooked is gas appliance servicing for homeowners.

Hot water is easy to take for granted. Then suddenly you don’t have it, and it’s the end of the world! Thankfully gas hot water heaters usually provide warning signs before they stop working. Know the signs your system is on the brink so you can book your gas hot water heater repair before the hot water runs out.

Rotten Egg Smell 

First, if you ever smell a rotten egg smell, immediately vacate the premise and call 000. The rotten egg smell is a sign of a gas leak, and professionals need to deal with it. 

Hot Water System Leaks

Leaks are never a good sign. If you see water dripping from your gas hot water tank or pooling under the unit, call a Bayside plumber who is also a gasfitter. It’s possible the values aren’t fully closed, or a connection may need tightening. However, if the tank leaks, you may need to replace it. 

Yellow Pilot Light Flame

A yellow pilot on a gas hot water heater means it’s not getting enough oxygen. Plus, there could be a potential carbon monoxide leak if your pilot light is not blue. 


Colourless and odourless, carbon monoxide can be deadly. Therefore, for this reason, you must immediately contact a gas fitter immediately for a gas hot water heater repair. 

Unusual Noises

No appliance is entirely silent. However, if you hear banging or rattling, there could be a buildup in the water storage tank. Avoid unusual noises with regular gas hot water system servicing. 

Inconsistent Water Temperature

If you rarely get hot water, or your water runs hot one day and cool the next, you may need a gas hot water system service. 

Age of Your Water Heater

A continuous flow gas-powered hot water system can last 8-12 years on average. However, depending on the usage, they may last less. Check your system’s date to determine if it is at the end of its lifespan as it may need to be replaced. 

Bayside Gas Hot Water Heater Repair

You can DIY a lot of plumbing issues, but professionals should always complete gas hot water system repairs. Most hot water systems connect to gas mains or electrical and contain scalding hot water. So always have a licensed gas plumber do your gas hot water system repairs.
