It was installed this week since we are waiting for our new countertops. It is easy and straightforward with the instructions. We compared this one with G3P600 and found out they both have the same RO system, with G3P600 is higher price because it has a reading panel shown about the parameters on the outlet tube.

Kind Regards Mia Lauren Customer Service Rep **Q: What is the difference between the G2P600 and G2?** A: Hi, Thanks for your interest in our G2P600 RO System. 1. Things in common: -Undersink water filtration systems with reverse osmosis technology, which can remove more than 1,000 contaminants from the source water. -Tankless, integrated waterway and composite filters ensure easier installation -Filter service life indicator; BPA- and lead-free material 2. Differences: The G2P600 is a more advanced model compared to G2, which shows better performance in these aspects: -The drain water ratio of G2P600 is 2:1; which gives this new model the ability to produce the same amount of filtered water at the cost of 50% less waste water (compared to G2). -As a benefit of the fast flow rate (600 gallons per day), you can fill a cup of water in 8 sec, which is a significant improvement compared to G2's flux of 400 GPD. With these new features, the new G2P600 is more than enough to meet the daily needs for water of large families, and even for small companies.

It was installed this week since we are waiting for our new countertops. It is easy and straightforward with the instructions. We compared this one with G3P600 and found out they both have the same RO system, with G3P600 is higher price because it has a reading panel shown about the parameters on the outlet tube.

Great tasting and clean water. ### ⭐⭐⭐⭐⭐ Recommended (but get the mini tank too) *by A***R on November 23, 2025* 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. ## Frequently Bought Together - Waterdrop G2P600 Reverse Osmosis System, 600 GPD Tankless RO Water Filter System, Under Sink RO System, 7 Stage Filtration, 2:1 Pure to Drain, Reduce TDS, FCC Listed, USA Tech - Waterdrop Remineralization Under Sink Water Filtration, 1/4” Quick Connect Post Filter for RO Reverse Osmosis Filter System, Restore Essential Minerals --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/211359093-g2p600-under-sink-ro-system-600-gpd-tankless-ro-water](https://www.desertcart.sg/products/211359093-g2p600-under-sink-ro-system-600-gpd-tankless-ro-water) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-21*
