Who it fits
Good fit for
You should consider this system if you need high daily output without waiting for tankless units to fill. The 100 GPD capacity suits larger families or those who drink significant water. The non-electric design is ideal for areas with unstable power. The compact, housing-free shape fits tight under-sink spaces. The included 3/8" and 1/2" adapters make it versatile for various US kitchen plumbing setups. You will appreciate the factory pre-assembled, pressure-tested unit for straightforward DIY installation.
Who should skip it
Skip this model if you require a tankless system for unlimited instant flow. This unit includes a 2.2-gallon tank, so you will run out of stored water during heavy use. It is not portable despite the "Portable" attribute in some data; it is designed for fixed under-sink installation. If you need smart features, app connectivity, or remote monitoring, this system lacks those electronic components. It also does not include a dedicated faucet or post-filter in the provided specs, so check your faucet compatibility separately.
Verdict: This is a robust, efficient under-sink RO system for households wanting high capacity and leak protection without electronic complexity.
Rebla Water Key Specs Explained
Capacity (GPD): 100
This rating indicates the system produces 100 gallons of purified water per day. You get a faster refill rate for your storage tank compared to standard 50 GPD units. This is useful for larger households or frequent use. It helps ensure you have enough clean water for cooking and drinking without long waits.

The tank holds purified water for immediate use. The quick-connect design allows you to replace filters without heavy wrenches. This reduces the risk of housing cracks during maintenance. The built-in leak sensor and pressure regulator provide continuous safety. They protect against pressure spikes and accidental water damage. You do not need to monitor the system constantly. The NSF-certified components ensure the water meets specific health standards. You get clean drinking water with reduced contaminants. The compact size fits under most sinks without crowding. You can place it in basements or garages if needed. The non-electric design means fewer electronic components to fail. This simplifies long-term ownership. You simply connect, test, and use. The system is ready for daily purified water production.
Before You Buy This RO System
You should verify your cabinet space before ordering. The unit measures 16.5 inches deep and weighs 18 pounds. Ensure you have enough clearance for the 2.2-gallon tank and quick-connect elbows. Check your sink’s water pressure. This system relies on mains pressure and does not need electricity. It works during power outages, but low pressure may slow production. Confirm your plumbing uses 3/8 inch or 1/2 inch lines. The box includes adapters for both sizes, so you likely do not need extra hardware. Plan for regular filter changes to maintain the 99% contaminant removal rate. This model suits homes wanting a reliable, non-electric option. It differs from tankless systems that require power. It also offers faster production than 50 GPD units. If you prefer simplicity and leak protection, this fits well. If you need smart monitoring, look elsewhere.
Check before you buy
- Measure cabinet depth to ensure 16.5-inch clearance.
- Confirm water pressure meets system requirements.
- Check plumbing line size for adapter compatibility.
- Plan for routine filter replacement schedules.

Frequently asked questions
Is the Rebla Water system NSF Certified?
Yes, the unit is NSF Certified. This certification ensures the materials and filtration components meet specific safety and performance standards for drinking water treatment. You can trust that the system has been tested against established public health guidelines. This adds a layer of verification to the product's claims regarding water quality and material safety.
Does this RO system require electricity to operate?
No, the system does not require electricity. It operates using standard household water pressure to push water through the membrane and filters. This makes it suitable for locations where an electrical outlet is not available under the sink. You avoid the complexity of wiring and the risk of power outages affecting your water supply.
What is the daily water production capacity?
The system produces 100 gallons of purified water per day (GPD). This higher output allows for quicker refilling of the 2.2-gallon storage tank compared to older 50 GPD models. It is designed to handle the demands of larger households or frequent use without significant waiting times between fills.
How much space does the unit take up?
The main unit measures 16.5 inches long, 9.25 inches wide, and 15 inches high. It weighs 18 pounds. The housing-free design with quick-connect elbows helps save space under your sink. You should ensure your cabinet has enough clearance for both the unit and the separate storage tank.
Is the system easy to install without professional help?
The system arrives factory pre-assembled, which simplifies the process. It includes color-coded tubing to help you connect the components correctly. You will need to attach it to your kitchen sink plumbing using the included adapters. The design aims to make setup straightforward for users with basic plumbing skills.
What is the drain-to-pure water ratio?
The unit has a 1:2 pure-to-drain ratio. For every two gallons of clean water produced, one gallon is sent to the drain. This ratio is more efficient than older systems, helping you conserve water while still maintaining effective filtration. It balances performance with resource efficiency for everyday drinking water needs.
