Why is the exhaust valve not exhausting but continuously inhaling?

[Brown]

The reasons and solutions for the exhaust valve not exhausting but continuously inhaling are as follows: 1. Exhaust port blockage: The exhaust port of the exhaust valve is blocked by foreign objects. It is necessary to unscrew the exhaust valve and remove the foreign objects inside. The main reason for the blockage is the poor quality of the exhaust valve. 2. Misalignment of the floating device: Gently tap the exhaust valve with a rubber hammer to restore it to its original position. If it cannot be reset, use water pressure to clean it. The working principle of the automatic exhaust valve is to use the buoyancy of water to block the vent.
