When using the water heater air vent valve, we need to prepare a small bucket to receive water and air in the water heater. Drainage buckets should be properly placed to avoid danger caused by water overflow.
3. Be careful when operating the air vent valve
Especially cautious when operating the valve in case that  the water and gas in the water heater splash out and cause personal injury.

Although the water heater exhaust valve is a small part, it influences a lot. We need to pay attention to the water heater exhaust valve when using the water heater,so water heater and its service life can be longer.
