Curator's pick: Waterdrop G3 Reverse Osmosis System
The tankless design is a win for serviceability because it eliminates the bacteria-prone pressure vessel and saves half your cabinet space. Just watch the power requirement; you need a dedicated outlet under the sink that most older kitchens don't have.
⚠ Worth knowing: These quick-connect fittings are convenient but unforgiving if your poly-tubing cuts aren't perfectly square. If you don't use a proper tube cutter, you’ll likely deal with a slow drip that can rot your cabinet floor over time.
