What makes it stand out
The TROE800COL has two features that separate it from most under-sink RO systems at this price tier: the smart faucet and the 2:1 waste ratio.
The smart faucet displays both incoming source water TDS and outgoing filtered TDS simultaneously — you can read filter performance without pulling out a separate meter. When the gap between the two readings narrows over months, that's your membrane aging signal. At 800 GPD the system produces purified water fast enough to maintain the 2:1 ratio, which is meaningfully more efficient than the 3:1 or 4:1 typical of conventional systems at lower output ratings. Less wastewater matters both for utility bills and for households in water-conscious regions.
The tankless design keeps the under-sink cabinet clear — no pressure tank occupying the floor space. For kitchens with tight cabinets or where under-sink storage matters, this is a practical advantage.
Pros
- 800 GPD — high output for large households and fridge supply
- Smart faucet shows input and output TDS simultaneously
- 2:1 pure-to-drain ratio — more efficient than typical
- Tankless — no pressure tank occupying under-sink space
- USA customer support
- Positive reviewer sentiment overall
Cons
- Installation is tricky on single-sink or garbage disposal setups
- Some kitchens require drilling a new faucet hole
- Included feed adapter and manual not universally praised
- May require a plumber for non-standard plumbing layouts
Installation — what to check before ordering
Check your drain configuration
Garbage disposal hookups make drain saddle placement more complex. If you have a garbage disposal, check whether there's an accessible port for the RO drain line before ordering. Some configurations require an additional drain tee.
Check your faucet hole situation
The smart faucet requires a dedicated faucet hole. If your sink doesn't have a spare hole, you'll need to drill one (granite or composite sinks typically require a professional) or use a soap dispenser hole if available.
Standard plumbing = DIY-feasible
For a standard layout (spare faucet hole, accessible cold water supply, clear drain connection), the install is manageable in 1–2 hours with basic tools. If any of the above conditions aren't met, budget for a plumber call.
Filter replacement schedule
| Stage | Filter type | Typical interval |
|---|---|---|
| Stage 1 | PP Sediment | 6–12 months |
| Stage 2 | Carbon Block | 12 months |
| Stage 3 | RO Membrane | 18–24 months — monitor via smart faucet TDS display |
| Stage 4 | Post-Carbon | 12–18 months |
Use the smart faucet TDS display as your primary membrane indicator. When rejection rate (1 − output TDS ÷ source TDS) drops below 85%, replace the membrane regardless of time elapsed. TDS monitoring guide →
Common questions
Is the Brio AQUUS hard to install?
Standard plumbing is DIY-feasible in 1–2 hours. Non-standard setups — garbage disposal connections, no spare faucet hole, tight cabinet layouts — add complexity. Check drain access, faucet hole availability, and cold water supply accessibility before ordering.
What does the smart faucet show?
Both incoming source water TDS and outgoing filtered TDS simultaneously. This lets you calculate rejection rate in real time and see when the membrane is degrading — without a separate meter. When the gap between source and output TDS narrows over months, the membrane is due.
What is the 2:1 ratio and why does it matter?
For every 1 gallon of filtered water produced, the system discharges 2 gallons of waste water. Most conventional under-sink RO systems discharge 3–4 gallons per gallon filtered. The 2:1 ratio reduces both water waste and drain flow — meaningful for water-conscious households or areas with high water costs.
Who is this system best for?
Households wanting high throughput without a pressure tank, buyers who want built-in TDS monitoring on the faucet, and anyone wanting to supply a drinking faucet and a fridge or ice maker simultaneously. Standard plumbing is important — complex layouts may require professional installation.
