Brio G20-U Tankless (Black, 46.2cm x 13.2cm x 41.9cm)

How much space does this system require under the sink?

The system measures 46.2cm wide, 13.2cm deep and 41.9cm tall, using approximately 30% of typical under-sink space. This leaves 70% of your cabinet free for storage. You'll also need access to a power outlet as the system requires electricity to operate the smart faucet display and filtration process.

What's the difference between the two faucet handles?

One handle dispenses PCB-filtered water that removes chlorine, sediment and improves taste whilst producing no wastewater. This is ideal for washing vegetables, watering plants or general kitchen use. The other handle provides RO-purified water that removes 99% of contaminants including heavy metals, fluoride and PFAS - perfect for drinking, cooking and baby formula preparation.

How often do the filters need replacing and what do they cost?

The PCB filter requires replacement every 6-12 months and costs around £50. The RO membrane lasts 12-24 months and costs approximately £170. Replacement frequency depends on your water quality and usage. The smart faucet displays filter life percentages so you know exactly when replacements are needed.

Can I install this system myself?

Yes, the system includes all installation components and detailed instructions for DIY setup. You'll need to connect to your cold water supply, install the faucet through a countertop hole and connect to a drain line. Most installations take 2-3 hours. However, you may need an electrician if there's no power outlet under your sink.

How does the water flow rate compare to traditional tank systems?

The system dispenses one cup of water in under 8 seconds, which is slower than pressurised tank systems but provides continuous flow without running out. Traditional tanks deliver water quickly initially but require 10-15 minutes to refill once empty. This tankless design never runs out during high-demand periods.

What contaminants does the system remove?

The NSF-certified filters remove sediment, chlorine, iron, TDS, PFAS, atrazine, lead, arsenic, nitrates, fluoride and radium. The 0.0001-micron RO membrane eliminates 99% of dissolved solids and contaminants. The PCB pre-filter handles chlorine, taste and odour issues whilst protecting the RO membrane from premature fouling.

How much water waste does this system produce?

The system operates at a 2:1 pure-to-drain ratio, meaning for every 2 cups of purified water, only 1 cup goes to drain. This saves over 300% water compared to traditional 1:4 ratio systems. Using the PCB-filtered water option produces zero wastewater for non-drinking applications.

What happens if I need to move or service the system?

All connections use push-fit quick connectors that disconnect easily without tools. The system can be removed and reinstalled quickly if needed. Filter changes happen from the front without moving the unit. The compact design and lightweight construction make relocation straightforward compared to bulky tank-based systems.
