What is the reason why gas water heaters need to turn on two faucets at the same time to ignite?

First, the gas water heater is not easy to use, first of all, we must consider the flow of water. It is recommended to check the outlet of the hot water faucet. If it is small, it may be caused by insufficient water flow. Because the gas water heater is water-controlled, there is a minimum water flow requirement, which cannot be met, and the water heater cannot be deflated and the igniter cannot be turned on, so it cannot be used.

Second, the cold water is normal and the hot water is less. We should consider why there used to be more hot water, but now there is less. The reason is that the more scale deposits, the problem of blocking the pipeline, the water flow rate does not meet the conditions, and the water heater can not be ignited.

Third, in this case, the problem is at the outlet, not at the inlet. The water output will affect the inlet pressure. Please check the exit passage.

1, the water flow switch can be adjusted to the minimum.

2. Try to loosen the screw of the microswitch, move towards the water-gas linkage switch and then tighten the microswitch.

3. After moving the linkage switch, observe the operation of the ejector pin of the water-gas linkage switch. If it doesn't move or only moves a little, it is that the diaphragm is broken and needs to be replaced.
