Which of the following statements regarding the failure of the water seal is incorrect? ( ) A Water seal failure occurs when, for some reason, the height of the water seal decreases to an extent that it is no longer sufficient to withstand the allowable pressure changes in the pipeline. B The lower the height of the water seal, the weaker its ability to resist pressure fluctuations in the pipeline. C Self-siphonage losses and induced siphonage losses can cause a loss of water volume, while evaporation and capillary action do not lead to such losses. D Self-siphonage losses refer to the loss of water volume from the water seal itself that occurs when sanitary fixtures discharge large amounts of water instantly. Answer: C
C. Siphonage loss and induced siphonage loss can cause water loss, while evaporation and capillary action do not cause water loss
