The maintenance method is to check whether there is leakage of gas pipe of the water heater, if so, replace it; check whether there is any defect of the burner of the water heater, if so, replace it. Finally, the fault that the water heater is not hot enough is caused by the burner of the water heater can not work normally or the capacity of the water tank of the water heater is not large enough. The maintenance method is to check whether the burner of the water heater is working normally, if not, replace it; check whether the capacity of the water tank of the water heater is enough, if not, replace it. Above is the introduction of the common faults and maintenance methods of gas water heaters. I hope it can help you.
