Rubber cup B10

Does your 10 liter Bonamat tank leak from the tap? Most often the reason is the swing acting as a faucet shut-off. It is easy to replace independently when the tank is empty, turn the tap open counterclockwise, grasp the silicone swing and pull it out by squeezing. Press the new swing into place on the tap and screw the tap onto the tank. Test the tightness with cold water, for example.
