The new bilge pumps operate using an internal level sensor that activates them when the water reaches 5 cm in height and deactivates them when it is removed. The Auto Sense Intelligence technology enhances their functionality. In case the level sensor becomes contaminated, the backup mode prevents the pump from running continuously, protecting the battery, while maintaining automatic operation. The pumps are equipped with a non-return valve to prevent reverse water flow, which can cause unpleasant odors if stagnant.
