Product review (5 stars): May be the solution to your clogged water filter waste water line
Was having problems with where I had my waste line for the water filter located. It was near the trap and would get clogged from time to time. I added this to the setup and closed off the old hole by replacing the piece that I drilled. This mounts at the top of the disposal to an auxiliary fitting that I had to knock out the block in it. Once I installed this, NO MORE CLOGS. This should have been mentioned of offered by the water filter company as a solution.
