When the gas water heater in your home is used for a long time, you will find that the aging phenomenon of the water heater is more serious, resulting in various failures and bringing safety hazards to people's use. Today, we will take you to repair your water heater at home by identifying these faults! 
1. Analysis of common soft faults of gas water heaters.
Gas Water Heater Troubleshooting:
A: Water heaters use water pressure to open gas channels. When the water pressure is lower than 0At 02MPa, it is normal for the gas water heater to not catch fire.
B: The drain valve drips because the water supply pressure is too high. The drain valve acts as a protective effect. It is normal to unload water and decompress to protect the gas water heater.
c: If you send hot water to multiple places at the same time, it will lead to a decrease in the amount of hot water, and even the difficulty of hot water.
d: Automatically turn off and the indicator light flashes during use. You've been using it for 20 minutes straight. This is because the timed flame-out safety device is already in effect. At this time, if you confirm that the space where the water heater is installed is well ventilated, you can restart the water heater.
e: The ignition controller is equipped with low voltage protection. When the battery voltage.
Quality inspection of gas water heater after repair:
After the gas water heater is repaired, the repaired water heater must be inspected for safety.
Answer: There should be no air leakage from the gas inlet to the burner fire hole (use an ignition gun to hit an open flame for inspection).
B: The pressure resistance of the water system (from the water inlet to the hot water outlet) is not less than 1There should be no leakage and no deformation under the water pressure of 0MPa for 1 minute.
C: The action of the water-gas linkage control valve device should be flexible and reliable, and the water pressure should be started (1The large amount of water should be 0Normal start under water pressure. 2.The small amount of water should be 0Normal start under water pressure. 0.water pressure).
D: After lighting a fire hole, the flame should spread to all fire holes within 2 seconds without deflagration. The flame should be clear and uniform, and there should be no black smoke, tempering, flame-out, flame separation and other phenomena that hinder use.
e: The smoke extraction system does not allow the smoke to be discharged from other places other than the smoke exhaust inlet.
f: If there is a safety device, it should have a 20-minute timer to prevent dry burning and accidental flame-out automatic protection function.
