The pump, which is screwed to the tap, creates suction from the flowing tap water so that water can be drawn out of the aquarium through a hose. After moving a lever, it can be filled again
Screw the water jet pump onto the water tap, connect the hose, open the water tap and move the lever position to select whether water is to be siphoned off or refilled
The water jet pump has a 3/4'' threaded connection. It needs to be attached to the tap thread (mostly M28x1; M22x1; M24x1) by means of an adapter (not included)
Package contents: 1 complete water jet pump (3/4'' connection) with stopcock incl. seal ring, movable hose connection (12/16) with hose locking nut
