RO Reverse Osmosis Water Filtration System, 600 GPD, 2:1 Pure to Drain, Tankless, Smart Panel, Composite Multi-Stage, FCC Listed, USA Tech, WD-G2P600-W

At the 2 year mark, I thought I would write a quick review. Installation was easy if you are a little handy and have a few basic tools. It has never leaked. It has worked absolutely flawlessly for 2 years. I had to change the sediment prefilter at 12 months, and again at 24 months. I had to change the Reverse Osmosis filter at 24 months. This was all in the time frame I expected for moderate water use for 2 adults. The water tastes excellent, and the water flow has always been good. Very happy with this unit (G2P600).

Si viven en México consigan otro filtro, llevo 3 meses tratando de encontrar alguno de los filtros para reemplazar, y nada, voy a terminar comprando otro pero hecho en México. El filtro es bueno aunque no perfecto, use un TDS tester y aparece un poquito café, claro no se compara con lo negro que salió con el agua directo del grifo. Saqué un video cuando lo probé pero no lo encuentro, lo subo después si lo encuentro.

6 month review: Water tastes similar to vending machines and water stores. I have consistently measured filtered water TDS at 8-12 ppm. The discarded water measures TDS anywhere between 300-600 and it tastes like armpit sweat, so it is definitely working on both instrument analysis as well as taste test. I collect discarded water for watering house/patio plants, but it's nice that discard volume is low (1:1). It's installed in the garage sink and use it mainly for filling 5 gallon jugs (with food grade silicone tubing attached to the faucet into jugs) that are also stored in the garage. It takes around 5-7 minutes to fill 5 gallons. I appreciate the clean design as the main unit is installed under a utility sink where it is easily visible.

The Waterdrop G2P600 is an excellent reverse osmosis system (RO). We previously had a big tank RO but after a gallon or two it would slow down until there was just a trickle from the faucet. Then we would have to wait for the tank to refill. Having a continuous flow RO is a huge plus. And it takes up less than half the space as our old RO & tank. I had some concerns about the noise of the pump but honestly we keep it under the sink and when the doors are closed it's barely noticeable. However that we had one minor problem. There is a pause when you turn the faucet on. That momentary pause did not play well with our refrigerator ice maker. It made some loud noises. So I highly recommend if you are going to connect this RO to the refrigerator you buy the tank as well. (Waterdrop PMT Small Water Pressure Tank.) And then bleed a lot of water through the fridge to remove any potential bubbles in the line. Now there's no momentary lapse and the ice maker is quiet once again. You can see just how small the tank is compared to the RO in the attached picture. It was a very easy install and made a huge difference. Here's my water measurements in Total Dissolved Solids (TDS) measured in parts per million using the Craft911 water tester: 249 tds from the hose 324 tds from the sink (from a water softener) 34 tds from our old RO 12 tds from the G2P600 RO That's quite an improvement. Some day I'll have our water tested just to see what's actually in there and what the G2P600 is removing from the source. So I highly recommend the G2P600 and tank. This is proving to be one of my best Amazon purchases.

Easy to install. Instructions are easy to follow. The faucet is nice and sturdy. Goes well with our stainless steal sink. We use it with a cistern system that we fill with tap water; water tastes great from the filter system. Filters are easy to change. I would recommend. I got a bit screwed on the price. Looks like the price dropped to $269 right after I purchased it for $299.
