WP164020 DLA-D Drain Line Plumbing Adapter for Garbage Disposal, Universal, White

Worked like a charm. I had my Reverse osmosis filter which has a drain pipe which went inside the drian line adapter and got locked. My Dishwasher drain pipe went into the main line. I tested the funcitoning and there was absolutely no leakage from any of the line.

Pretty easy to install and now my sink works nicely!

Perfect little device for the job. It fit exactly as promised. Instructions were clear and easy to follow. This only works with an existing disposal. Watts offers a different version if you don't have a disposal. This device costs more than just a simple drain tap, but it makes service and testing much much easier. Example. I wanted to know if the shut off valve was working properly. Because this device uses a quick connector, it was easy to pull out the waste tube, put a bucket below, and see when system was running. Also, it makes the system quiet. Before installing this, I had a simple drain tap, I could hear the dripping when the RO system was running. Sometimes I'd forget and run around trying to figure out what was leaking. Now, I can't hear the water drain at all. Totally silent. Hence, the testing method above. The plastic is a more brittle than I expected, much more like PVC than ABS or rubber hose. It doesn't give. So, when I cut off the end, it snapped, I was afraid I'd broken it. The picture shows two clamps but mine only came with one. I don't see why two would be necessary. It is good and water tight even before I used the clamp.

Perfect solution if you cannot access a good position for your drain saddle. Assembles quick and works great.

Easy install found this because I read bad reviews and aske co-pilot about my gurgling primer osmosis installed wrong during kitchen model attachment to dishwasher drain
