Recipient of an honourable mention at the Red Dot Awards 2016 for design and innovation, the Panama space-saving syphon is a complete waste system that gives you the space underneath your kitchen sink back. With an integrated rubber valve that replaces the trap, it is the weight of the water that pushes this flexible valve to one side to allow water to be discharged in the drain. Once the water stops flowing, it simply closes the trap so no water or foul smells can make their way back up.Installation is very simple as the space-saving syphon is connected directly to the drain and with only three couplings instead of the usual five, there are fewer points where leaks can occur. It is suitable for all new and pre-installed single-bowl kitchen sinks and can even be used in conjunction with a waste disposal unit.
