The water intake must exceed the set water level before it will stop

Analysis and maintenance: This phenomenon shows that when the actual water level has reached the specified height, the air pressure in the water pressure switch collecting room is still not up to the specified value, and only if the water level continues to rise, the water pressure switch will operate. The specific reasons and treatment methods are:

(1) The gas inlet of the water pressure switch gas collecting chamber is blocked or leaked. Just remove the debris at the gas nozzle; Or seal with 401 glue at the leak. If the air hose is aging and kinked or cracked, replace the air hose.

(2) The pre-compression of the water pressure switch water level control spring is too large. As long as the adjusting screw out some, reduce the water level control spring pre-compression.

(3) The reversing ejector rod and transmission components in the water pressure switch are deformed or damaged. It can be solved by repair and correction, and the water pressure switch should be replaced in serious cases.以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景
