Description
Tankless 800 GPD Reverse Osmosis System
No storage tank. Fast flow. Twist-lock filter changes. Clearance pricing while supplies last.
The Tankless 800 makes purified drinking water on demand instead of storing it in a pressure tank. That means a compact unit under your sink, fresh water every time you open the faucet, and strong flow for filling pitchers and pots.
6-Month Risk-Free Trial
If you're not happy with your Tankless 800, return the complete system within 6 months — even if it's been installed and used — for a full refund of the purchase price, with no restocking fee. Return shipping is paid by the customer. See full return policy.
Why Choose Tankless RO?
- Fresh water, never stored. A tank-style system holds water for hours or days. This one makes it when you need it.
- Fast flow. About 2 liters per minute. Fills an 8 oz glass in about 7 seconds.
- Less wasted water. About 1 gallon to drain for every 2 gallons of purified water. Many conventional RO systems send 3 to 4 gallons to drain for every 1 gallon they make.
- Frees up cabinet space. One compact unit (14" H x 5-1/2" W x 16" L) replaces the filter housings and the tank.
Features
- 4 stages of filtration. Sediment, activated carbon, fine sediment, and reverse osmosis.
- Two twist-lock cartridges. One combined sediment/carbon cartridge and one RO membrane. No tools, no mess.
- Smart faucet with status ring. Glows blue when the system is working and red when it's time to change filters.
- Filter-life monitoring and auto-flush. The control panel tracks filter life, and the system flushes the membrane automatically to keep it clean.
- Built-in leak protection. Shuts itself off if water runs continuously for 30 minutes.
- Refrigerator connection. An extra outlet can feed filtered water to your fridge's water and ice maker.
Easy, Affordable Maintenance
- Sediment/Carbon Replacement Cartridge: $69, replace every 6 to 12 months
- RO Membrane: $119, replace every 1 to 2 years
Actual filter life depends on your water quality and daily use.
Good to Know
Because a tankless system makes water on demand, it takes a few seconds after you open the faucet for the pump to start and purified water to flow. This is normal for all tankless RO systems. If your system takes much longer than that, give us a call. Low water pressure or an installation issue is usually the cause, and we'll help you sort it out.
Water Requirements
- City water or well water that meets drinking water standards
- Water pressure between 15 and 60 psi (add a pressure regulator above 60 psi)
- Total dissolved solids (TDS) of 500 ppm or less
- Cold water only, 41 to 100°F
On well water? For best results, feed water should be softened below 10 grains per gallon with no iron. Not sure about your water? Ask our water specialists.
What's Included
Everything for a DIY install under a standard sink:
- Tankless RO unit, sediment/carbon cartridge, and RO membrane
- Smart faucet with status ring
- Power adapter
- 1/4" and 3/8" tubing
- Feed water valve, drain saddle, and refrigerator adapter
- Fittings, Teflon tape, and spare O-rings
You'll need: a standard 110V outlet under the sink, plus a drill and 1" hole saw if your sink doesn't have a spare faucet hole.
