Gas water heaters commonly fail due to sediment buildup, age, faulty heating elements, thermostat issues, gas valve failures, pilot light problems and improper venting. We offer expert diagnosis and repair of all gas water heater brands and models in Pennant Hills to get your hot water running again.
Determining the cause of gas water heater failures is essential for efficient troubleshooting and repair. Pennant Hills Plumbing’s experts are adept at resolving a range of issues.
Gas water heaters may fail for numerous reasons, including inadequate water pressure. Typical problems include:
Regardless of the cause, if turning on your hot water tap yields no response, our skilled plumbers can diagnose the issue using advanced techniques and the latest equipment. Once we identify the fault, we deliver optimal repairs to guarantee a consistent hot water flow.
Our technicians are available for same-day and emergency appointments to swiftly restore your gas hot water system, making sure the service panel circuit breaker is correctly set.
A gas water heater can malfunction due to several common issues:
A pilot light outage causes the burner to shut off, preventing your water from heating. Quick action is needed to relight a weak pilot flame or fix a malfunctioning thermocouple. Our technicians can swiftly resolve pilot light issues and ensure your hot water tap functions correctly through comprehensive troubleshooting.
If your thermostat is not calibrated correctly or fails entirely, the gas line may be compromised meaning the gas burner may not ignite or may not heat the water to the proper temperature. An ideal warm water temperature of 49°C prevents scalding and reduces cold water wastage. We’ll make sure to test and adjust the thermostat for optimal hot and cold water temperatures if needed.
Defective gas valves won’t allow gas to pass through to the burner. This prevents ignition. A faulty gas control valve may require our plumbers to replace components or the entire valve.
Sediment and hard water deposits can build up in the tank, leading to overheating and failure. We will drain and flush the tank to remove sediment accumulation.
Regardless of why your gas electric water heater fails, Pennant Hills Plumbing technicians are equipped to diagnose the issue accurately. We work swiftly to restore your hot water, knowing the importance of keeping your heater operational.
The pilot light ignites the burner in your gas water heater. Without it, the burner won’t ignite, leaving you without hot water.
This results in a lack of hot water supply.
There are a few common reasons why a gas water heater’s pilot light malfunctions:
If you’re without hot water, check if the pilot light is out. You can relight it as follows:
If the pilot won’t stay lit, most likely resulting in no hot water, your plumbers at Pennant Hills Plumbing are here to help. Our gas fitting experts can fully inspect your heater pilot light assembly. We’ll clean or replace parts as needed to restore hot water.
A thermocouple is a small device inside your water heater’s assembly, designed to shut off gas to the pilot to prevent leaking water and gas. It senses whether the pilot flame is lit. If the pilot goes out, the thermocouple sends a signal to shut off the gas supply for safety.
Thermocouples can degrade or become blocked by sediment, which hinders flame detection, causing pilot light failures and inconsistent water temperature.
Recognize the signs that indicate your thermocouple needs replacement:
It’s essential to replace a faulty thermocouple for a properly functioning water heater. At Pennant Hills Plumbing, our gas plumbers will:
Trust our expertise to get your hot water working again by ensuring a fully functional thermocouple.
The gas control valve, or gas thermostat, is a crucial safety component in gas water heaters. When the pilot light signals for heat, this valve opens to allow gas flow to the burner. The temperature pressure relief valve is triggered when water pressure reaches a pre-set threshold, preventing overheating.
A A defective gas control valve necessitates professional repair, rather than DIY attempts, to ensure gas reaches the burner. As a result, the pilot light remains on, but the main burner fails to ignite. Indications your valve needs replacement include:
Gas valves contain sensitive electrical and igniter components. Attempting a DIY install risks serious safety hazards plus additional damage if installed improperly. For this reason, our technicians always recommend leaving gas valve replacements to qualified professionals.
At Pennant Hills Plumbing, we have extensive training and experience with gas appliance repairs. Trust us to accurately diagnose your failed gas valve and restore hot water by installing a fully functional OEM replacement part.
Sediment buildup, resulting from hard water deposits, can obstruct the dip tube and settle at the tank’s base, leading to inefficient heating and strain on your water heater. The strain can cause overheating and early failure.
Anode rods in water heater tanks safeguard against corrosion; we inspect and advise on replacement during service calls, particularly for rods older than 10 years.
Sediment removal and anode rod replacement helps common water heaters run efficiently for years. Contact Pennant Hills Plumbing to maximise your hot water heater’s life span.
Routine maintenance on your gas water heaters extends their lifespan and reduces the likelihood of malfunctions. We recommend inspecting your water heater about every year and flushing the tank to remove sediment buildup, thereby improving hot water usage. Replacing the anode rod every 3-5 years also prevents tank corrosion.
Check around the water heater several times a year for any drips or leaks. Catching minor leaks early helps check your unit’s health and prevent major failures down the road. If you find a leak, your plumber from our team should be contacted right away.
During power outages, limit water usage to conserve hot water until normal power supply resumes. The pump in gas water heaters relies on electric power, so disrupted power water means the water heater can’t churn and process water adequately. Running the tank dry can damage the heating element, which is supposed to heat up when your power returns.
Proactively maintaining your hot water system and monitoring for leaks can significantly extend the lifespan of your hot water tank.
To prevent unexpected gas water heater failures, we recommend arranging annual tune-ups with our technicians. During these routine inspections we will:
Staying on top of maintenance helps gas water heaters operate safely and efficiently for years to come. It prevents minor issues from becoming major repairs down the road. With regular upkeep, you can avoid unexpected failures that leave your household without hot water.

It’s important to periodically inspect your gas water heater for any signs of leakage. Small leaks often occur off your water pipe fittings and valves, but can also happen through tiny cracks in the tank itself.
Check around the lower section of your water heater a few times per year. Scan for wet spots or mineral deposits, which can often signal drips, on the floor. Leaks near the top water heater can often be repaired more easily than leaks towards the base which may require full replacement.
If you find a leak, take caution as leaking gas is a potential fire or explosion risk. Turn off the gas supply swiftly and call your team of plumbers at Pennant Hills Plumbing to assess and repair your water heater.

The anode rod is a crucial component that protects the inner tank of your gas water heater from corrosion. Over time, this rod slowly corrodes, which preserves the steel tank. Replacing this rod every 3-5 years extends the life of your water heater.
