Watts Premier Universal Dishwasher / Drain Line to Garbage Disposal Adapter for Reverse Osmosis Systems, Push-In Fitting & Barb, Hose Coupler, Marine Stainless Steel Hose Clamps, No Drilling Required

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.

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

I'm somewhat torn on rating it with 5 stars. It fits perfectly, install took less than three minutes and works perfectly, except the noise. The discharge is incredibly loud, especially after someone gets up for water in middle of the night. I might try another alternative if I can find one.

This product absolutely does work. You can avoid the drain line saddle tap with this device. Ordered because it eliminates the exposure to the garbage disposer feeding garbage back through the drain line to the air gap in the faucet. But I also ordered one directly from Watts at their website and that one arrived a week before the one I ordered from Amazon.

I wish it wasn’t as long, but it works way better than drilling a hole in the tail piece for a saddle connection. I broke that doing a reinstall on a new kitchen sink, the new sink was also a single bowl, so a saddle connection on the piece out of the disposal wasn’t a good option in the first place. They should sell the reverse osmosis filters with this thing in the first place.

It is absolutely amazing invention. I recently installed RO system under the sink and I had no space to put the outlet pipe. As per RO system, I need to drill hole in the sink outlet above the “U” stoppage. The space was tight and I was not confident enough to drill hole in running pipe. And then I found this product. It fits to the food disposal outlet and gives option for RO outlet perfectly. And you do not have to worry of making holes in the pipes. When you are doing DYI plumbing projects, you want avoid drilling holes in running pipe at any cost. Because if execution doesn’t go as planned, plumber will ripoff your pocket. So, go for it!

Wrong size for my RO system

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.

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

This is 100% perfect for my project. No leaks worked perfectly. No issues here. 100% recommended.

I was hooking up the drain of an RO to a dish washer drain. The size of the dish wash drain is smaller than what this was so I had to get a reducer. I got it from Canadian tire and is called a dishwasher drain connector. 1/2 to 3/4 in. It was simple to hookup with this and works well.

This piece solved me a big problem
