In this quick highlight, I’m showing the Ecoviva under-sink tankless RO system (800G) and what the install looks like in the real world. If you follow the instructions, it’s honestly a pretty easy setup, and I walk through the tubing/connector basics: the big tube is for the input, the red one is for drainage, and the thinner line goes to the faucet. I also share a couple of small install choices I made—like reusing some existing tubing under my sink and only swapping in the angle connector where I needed it. I also talk about the faucet install details, because that’s where leaks usually happen. My sink opening had a round base and the front has a flatter design, so I used sealant clay to properly seal the gaps before tightening everything from underneath (washer in the ring first, then the nut). Once it’s in, the faucet design really impressed me—the big display looks great, and it’s one of the sturdiest faucets I’ve seen on an RO setup. With enough space under the sink, you can also mount it cleanly using the metal bar and hook, and I’m aiming for around 20 ppm TDS, which is a solid drinkable range.
