Introduction to Hot Water Systems
Gas water heaters, providing on-demand hot water with a pilot light, work in tandem with electric models, which use elements to heat water, ensuring a dependable supply for your needs.
Gas and electric hot water systems swiftly heat water for your sinks and showers, while effectively serving your household appliances. Identifying why these units fail is key to restoring normalcy. Knowing common hot water system malfunctions is crucial for timely troubleshooting.
Common Causes of Hot Water Issues
Several hot water supply failures commonly occur in Epping households and businesses. Insufficient water pressure, ideally between 100-150 kPa, impedes efficient heat transfer. Leaks or frozen pipes also disrupt system performance and cause water loss.
Gas hot water systems may experience pilot light problems if gusts blow out the flame or it fails to ignite due to dirt buildup. Older units, often over a decade old, may have a faulty ignition system that needs replacement.A damaged gas pipe can halt gas flow, causing serious concern. For tankless heaters, power surges that trip breakers or blow fuses can disrupt operation.Sediment buildup within water tanks diminishes efficiency gradually.
Faulty Pilot Light
If the pilot flame goes out, a safety mechanism cuts off the gas supply, protecting your system. Before cleaning, turn off the power to your gas water heater to safely address pilot light issues, removing debris with a cotton swab soaked in vinegar or alcohol.
Start by turning off the gas valve at your water heater’s inlet to ensure safety. Ensure the gas supply is off before relighting to maintain hot water faucet safety, then carefully reactivate your heater.
Sediment Buildup
Over time, mineral deposits can accumulate in your water heater, restricting hot water flow. The calcification of the anode rod and heating elements can reduce heater efficiency and cause only lukewarm water to flow from your taps. Regular maintenance, such as using the drain valve to flush out sediment, is vital for prolonging the life of your tankless water heater. If you haven’t recently flushed your water heater, accumulated sediment can impair its performance, which might require professional attention.
Broken Dip Tube
The dip tube is a long plastic tube inside the water heater tank connected to the cold water inlet. If this tube fails, cold water may mix with the hot, resulting in a drop in water temperature. This predicament results in only tepid hot water coming through, as the heat is severely diluted, falling short of the ideal temperatures. It may become essential to replace your unit in its entirety if switching out the dip tube fails to correct the lukewarm water issue.
The dip tube directs incoming cold water to the bottom of the tank, facilitating its heating before it exits as hot water. An unnoticed malfunction in the dip tube can disrupt your hot water system, leading to erratic water temperatures.
Faulty Thermostat
The thermostat controls the temperature of the water inside your hot water system. Thermostats are calibrated to maintain water temperature safely within the recommended limits. A malfunctioning thermostat may undermine precise temperature control, leading to unpredictable water heating.
Faulty thermostat operations can lead to unexpected activation of heating elements or burners, signifying hot water issues.
Warning signs your water heater isnt working as expected include:
- The water your gas hot water taps provide fluctuates wildly in temperature
- Tap water is not hot but just lukewarm water
- Heating elements stay activated nonstop
- Energy bills that are higher than normal can also point to inefficiencies in a gas electric water system
Before replacing your entire electric water heater due to thermostat issues, try resetting the temperature first.
Adjust the thermostat by rotating the dial clockwise to increase or counter-clockwise to decrease the temperature as needed. If adjusting the thermostat fails to fix temperature issues, consider seeking professional assistance for replacement due to its complexity.
Troubleshooting Steps When You Have No Hot Water
Should your taps fail to deliver the cascading warmth, leaving you with no hot water your abode customarily relishes, contemplate these troubleshooting steps prior to seeking a plumber’s guidance:
- First, check that your hot water system is switched on. Find the switch or circuit breaker for your unit and make sure it’s set to the 'on’ position to continue delivering hot water to your home.
- Inspect the pilot light if you have a gas hot water system. Relight it if needed, being cautious to not light out prematurely, by following the manufacturer’s instructions printed on the unit.
- For electric units, if you’re puzzled by water heater inefficiency, try resetting the thermostat to 60°C.
- Check to see if the tempering valve is rightly set and the cold water inlet is fully open, confirming that the water pressure is within the optimal 150-500 kPa range. If you experience low hot water pressure, take steps to restore normal water flow.
- Press the pressure relief valve test button on the system to clear any trapped air inside that could prevent heating.
- After trying all steps and still lacking hot water, turn off the main power, take a short break, and then call us for advice before powering up again to re-evaluate.
- If your water is still lukewarm after following the recommendations, contact Epping Plumbing specialists at 1300 349 338 for further assistance or to discuss parts replacement.

Signs of Leaks or Tank Failure
Rust stains on your water heater or a sulfuric smell from gas units are indicators of potential problems. If the water temperature frequently fluctuates between scalding hot and lukewarm even after adjusting the thermostat, the tank may be compromised and losing heat. Using a heavily leaking or corroded water heater can pose safety risks, such as flooding, electrical malfunctions, or explosion hazards. If you notice these tank issues, contact our Epping plumbers for an inspection to determine if replacement is necessary before safety is compromised or damage worsens.
Visible water pooling around the tank is an obvious red flag. Loud rumbling or banging noises signal that your water heater isn’t functioning optimally. They can precede catastrophic tank failure. Several warning signals may shed light on the reasons why your hot water system could be leaking or approaching complete malfunction.
