Whale shower drain plug with water sensor - SG3484B

Sure. Here is a rewritten version of the text: Drain plug with built-in field sensor switch This drain plug has a built-in field sensor switch that automatically activates the Gulper IC pump as soon as water flows into the drain. This system allows you to drain grey water without having to flip a switch before using the shower or sink. The drain plug is small, made of robust materials and requires no maintenance or cleaning. A non-return valve is also built in and the drain plug is suitable for 19 and 25 mm hoses.
