Auto water change waste water

[Michael Biando]

I set up an auto water change system and currently my waste water goes into a 10gal container. I want to plumb it directly into the drain line coming out of my kitchen sink.
I saw a kit somewhere a while back that has all the parts to do this I just can’t remember who sells it. Does anyone know who sells it or have a good way to do this ?

They make a ro drain saddle for ro line, Amazon has it for $6-7.
