Frequently Asked Questions

Why is my gas hot water system not creating hot water?

A gas hot water system might stop heating because of a faulty pilot light, ignition system, burner, thermostat, gas control valve or flame sensor. Problems with the gas supply can also prevent the unit from providing you with hot water.

Why does my gas hot water keep going hot and cold?

Changing temperatures might be caused by a faulty tempering valve, thermostat, burner or heat exchanger. Continuous-flow systems can also fluctuate when the water pressure or flow rate is too low.

Why does the pilot light keep going out?

A pilot light may repeatedly go out because of a faulty thermocouple, dirty pilot assembly, gas supply problem or poor ventilation. Do not attempt to modify the gas controls yourself.

Why is my gas hot water system leaking?

Leaks most commonly develop around the storage tank, pressure relief valve, tempering valve, pipework or connections. Tank corrosion can also cause water to escape.

Can a leaking gas hot water system be repaired?

Leaks can be repaired by replacing a faulty valve, connection or section of pipework. But a corroded or damaged storage tank will most likely need to be replaced. A plumber can inspect the system and recommend the safest and most cost-effective option.

What should I do if I smell gas near my hot water system?

Turn off the gas supply if it is safe to do so, avoid flames and electrical switches, leave the affected area and call for professional assistance. Do not attempt to relight or repair the system. A suspected gas leak should always be treated as an urgent safety issue.

Is it better to repair or replace my gas hot water system?

Repair may be worthwhile when the system is in good condition and the fault involves a replaceable component. Replacement may offer better value when the unit is old, corroded, inefficient or experiencing repeated breakdowns. We assess the system before recommending either option.

How often should a gas hot water system be serviced?

Service intervals vary between manufacturers and system types, so check the maintenance schedule provided with your unit. Arrange an earlier inspection if you notice inconsistent temperatures, unusual noises, discoloured flames, leaks, ignition problems or reduced performance.

Do you repair storage and continuous-flow gas hot water systems?

G.X.R Plumbing & Gas can inspect different types of gas hot water systems, including storage and continuous-flow units. Contact us with the brand, model and symptoms so we can confirm the repair requirements and availability of suitable parts.

What brands of gas hot water systems do you repair?

We work with many leading gas hot water brands, including Rheem, Rinnai, Bosch and Dux. Repair availability depends on the model, age and availability of replacement parts. Contact us with your system details so we can confirm whether it can be repaired.

Do you provide gas hot water system repairs throughout Perth?
