HOW FREILAUF WORKS
With time, in all drains an ugly film of soap and grease builds up and has to be cleaned. All other drains have edges, gaps and angles that are very hard to clean. The Freilauf is everywhere smooth and round and easy to wipe off. Because the drain is smooth and has no obstacles in the water flow, the flow speed is high and there is less build up. So, the cleaning is not just easier, but also has to be done less often.
