PermaFLOW Self Cleaning Drain System
It's a replacement sink trap that improves the standard design in almost every way. First, it's see-through, which means if the sink isn't draining like it should, you'll be able to see why. Secondly, its unique design and shape increases the turbulence of the water while it's draining, which minimizes buildup. And thirdly, it's got an easy to use knob which turns an internal wiping mechanism that should easily clear up any clog. Brilliant.
