Waterdrop G3P600 Reverse Osmosis (600 GPD, Under Sink)

What contaminants does the G3P600 remove from UK tap water?

The system removes TDS, chromium, PFAS, radium, fluoride, arsenic salt, iron, calcium, particles, chloride, chlorine and radioactive substances. Third-party SGS laboratory testing confirms it also reduces vinyl chloride, ethylhexyl acrylate, isobutylene and ethylene glycol. In UK conditions, it typically reduces TDS from 300 ppm down to 7-17 ppm, representing a 95% reduction in dissolved solids.

How much space does this system require under the sink?

The tankless design measures 45cm length x 14.4cm width x 46cm height, saving 70% of under-sink space compared to traditional tank systems. Most UK kitchen sinks can accommodate this system whilst leaving room for cleaning supplies and other storage. You'll need access to electricity under the sink and space for the drain connection.

What certifications does this system hold for UK use?

The G3P600 is certified against NSF/ANSI 58 for TDS reduction, NSF/ANSI 372 for lead-free materials and NSF 42 for chlorine, taste and odour reduction. It's also certified by the Federal Communications Commission and meets EU Standards and UKCA Standards for safety, making it fully compliant for UK installation and use.

How often do the filters need replacing and what's the cost?

Filter replacement frequency depends on your local water quality and usage. The smart LED faucet displays filter life remaining, eliminating guesswork. When replacement is needed, simply search "WD-G3P600" for authentic Waterdrop replacement filters. The system includes three filters initially and replacement takes just 3 seconds without tools.

Does the system require professional installation?

Installation requires drilling two holes: one inch for the RO faucet and one for the drain pipe connection. You'll need under-sink electricity access. Many customers install it themselves using the included instructions and PDF manual. The system comes with all necessary components including the RO system, filters, LED smart faucet and accessories.

What's the water flow rate and how does it compare to mains pressure?

The system fills an 8oz cup in 8 seconds with a flow rate of 0.42 gallons per minute. Whilst this is slower than direct mains pressure, it's significantly faster than traditional RO systems. The 600 GPD capacity ensures consistent performance throughout the day, even with heavy usage from multiple family members.

Can I use any RO faucet with this system?

Waterdrop highly recommends using their authentic RO faucet for full compatibility with the smart display features. Other brand faucets may not be compatible with the TDS monitoring and filter life tracking functions. The included LED smart faucet is specifically designed to work with this system's electronic components and provide accurate readings.

What maintenance is required beyond filter changes?

The system includes a water collection tray underneath that needs periodic emptying to prevent overflow alarms. The unit will beep if the tray becomes full. Regular filter changes as indicated by the smart display are the primary maintenance requirement. The system automatically flushes after use to maintain membrane performance and extend filter life.
