What is the Express Water Tankless RO System?
The Express Water Tankless RO System is a reverse osmosis filtration system that purifies drinking water to the highest standard. Unlike traditional systems with bulky storage tanks, this tankless design saves space under your kitchen sink. It delivers fresh, clean water on demand. The system produces up to 600 gallons per day (GPD) of purified water, making it ideal for households that need a steady flow of clean water.
The innovation goes beyond its tankless design. It also features an alkaline filter that adds essential minerals like calcium, potassium, and magnesium. This improves both the taste and the health benefits of your water.
Key Features of the Express Water RO System
- Tankless Design: This space-saving feature is a game-changer for small kitchens. You won’t need to worry about sacrificing under-sink space for a bulky tank.
- 600 GPD Water Flow: This system delivers an impressive 0.4 gallons per minute, making it perfect for large households.
- Remineralization Filter: The system’s Active Mineral Technology enriches your water by adding back healthy minerals after the RO process strips them away.

How Does It Work?
The system uses a multi-stage filtration process, starting with sediment and carbon filters to remove larger particles, chlorine, and odors. The water then passes through a high-quality RO membrane, which removes up to 99% of contaminants, including lead, fluoride, and other harmful chemicals. Finally, the water goes through the alkaline remineralization filter to restore essential minerals, enhancing the taste and health benefits of your drinking water.
Benefits of Using a Tankless Reverse Osmosis System
Space-Saving Design
One of the standout features of the Express Water Tankless RO System is its compact design. Let’s face it: traditional RO systems can take up a huge chunk of space under your sink, thanks to their bulky storage tanks. This tankless model eliminates that problem entirely, freeing up valuable space for cleaning supplies or other items. It’s the ideal solution for modern kitchens with limited under-sink storage.
600 GPD Water Flow and Low Waste Ratio
Traditional systems often struggle to produce large amounts of water quickly. But with the Express Water tankless RO system, you’ll get up to 600 gallons of water per day—more than enough for even the busiest households. Whether you’re filling up a water bottle, cooking, or preparing coffee, this system has you covered. Plus, its 2:1 pure to drain ratio means less wasted water, making it an eco-friendly choice.
Remineralization with Alkaline Filter
Here’s where the Express Water system truly shines. Many RO systems remove essential minerals along with contaminants, leaving your water tasting flat. However, the alkaline remineralization filter in this system restores healthy minerals like calcium and magnesium, improving both the taste and health benefits of your water. This feature is especially important if you’re conscious about maintaining balanced pH levels in your drinking water.
Express Water Tankless RO System Drawbacks and Considerations
No product is perfect, and while the Express Water Tankless RO System excels in many areas, there are a few drawbacks and considerations you should be aware of before making your purchase. Let’s explore these points in detail to give you a complete picture.
Power Consumption
Because the Express Water system operates without a storage tank, it relies on electricity to function. This means it will need to be plugged into a power source, unlike traditional RO systems that can operate without power.
While the system doesn’t consume a lot of energy, it’s something to keep in mind, particularly if you live in an area prone to power outages. You may need to have a backup plan for access to filtered water during those times.
Installation Requirements
The installation process is relatively straightforward, which we’ll cover in the next section. However, this system can be more complex to install than traditional models due to its tankless design and electrical components.
If you’re not comfortable with DIY plumbing, hiring a professional might be necessary to ensure proper setup. This could increase the overall cost.
Maintenance Costs
The Express Water RO system keeps your water pure, but that level of filtration has a cost. Regular filter replacements are necessary, with expenses depending on usage and water quality.
Pre-filters usually need replacement every six months. The RO membrane and alkaline filter can last up to a year. While quick-twist filters make replacements easy, the long-term cost is worth considering when budgeting.
Installation Guide for Express Water Tankless RO System
One of the best features of the Express Water Tankless RO System is how relatively easy it is to install, even for someone without extensive plumbing experience. Here’s a quick breakdown of the installation process to help you get started.
Step-by-Step Installation Instructions
- Connect the Feed Water Adapter Valve: Begin by connecting the feed water adapter to your cold water line. This will allow water to flow into the filtration system.
- Install the RO Faucet: If your sink doesn’t already have a hole for an additional faucet, you may need to drill one. Once done, install the RO faucet according to the manufacturer’s instructions.
- Find a Location for the Drain Saddle: Attach the drain saddle to your drain pipe above the P-trap to ensure proper drainage of wastewater from the filtration process.
- Install the Quick Twist Filters: Simply insert the filters into their designated spots in the system, ensuring they’re securely fastened. The quick twist design makes this step easy and mess-free.
- Power Connection: Plug the system into a nearby electrical outlet to power the pump and filtration system.
Tools You’ll Need
- Adjustable wrench
- Teflon tape
- Drill (if necessary for the faucet)
- Filter wrench (included)
Common Installation Issues and Solutions
- Leaking Valve Solutions: If you encounter any leaks, it’s often due to connections not being tight enough. Double-check that the fittings are snug and the tubing is fully inserted into the connectors.
- Installing the Smart Faucet: The faucet comes with a built-in LED that shows the filter’s status (blue when fine, red when a filter change is needed). Ensure the wiring is properly connected during installation to avoid malfunctions.
Maintenance and Filter Replacement
Proper maintenance is crucial for ensuring your Express Water RO system performs at its best. Fortunately, maintaining this system is relatively simple, and thanks to the quick twist filters, it’s easy to replace filters without making a mess.
How Often Do You Need to Replace Filters?
Most users will need to replace the sediment and carbon filters every 6 months. The RO membrane and alkaline remineralization filter usually last around 12 months. Keep in mind that the lifespan of your filters will depend on how much water you use and the quality of your local water supply. For example, if your water has high sediment levels, you may need to replace the filters more frequently.
Cost of Filter Replacement
Filter replacements are affordable, but the costs can add up over time. On average, you’re looking at around $60 per year for replacement filters, but some users have reported higher expenses depending on usage.
Fortunately, you can purchase filter sets in bulk to save money, and Express Water even offers subscription services for regular filter deliveries at a discounted rate.
Tips for Efficient Maintenance
- Regularly Check the Water Flow: A drop in flow may indicate it’s time to replace the filters.
- Clean the System Periodically: Although tankless systems rarely have bacterial buildup, periodic cleaning keeps everything running smoothly.
- Use the Smart Faucet: The faucet’s built-in LED alerts you when it’s time to replace a filter, removing the guesswork from maintenance.
Water Quality and Contaminants Removed
One of the main reasons to invest in a reverse osmosis system is to ensure your drinking water is free from harmful contaminants. So how does the Express Water Tankless RO System perform in this regard?
What Contaminants Does the System Filter?
The system’s multi-stage filtration process removes over 99% of common contaminants, including:
- Lead
- Fluoride
- Chlorine
- Heavy Metals (Arsenic, Mercury)
- Total Dissolved Solids (TDS)
According to NSF certification, the RO membrane is capable of removing these contaminants to a near-zero level, making your water not only safe to drink but also tastier.
TDS Reduction and Water Taste Improvement
Water that passes through the Express Water system is remarkably clean, with TDS levels significantly reduced. The built-in TDS meter on the smart faucet gives you real-time readings, so you always know how pure your water is. In my experience, the taste of water after it goes through this system is vastly improved—no more weird aftertastes or chemical odors. Just crisp, clean water.
Why Alkaline Water Matters for Health
The alkaline remineralization filter isn’t just a gimmick. Alkaline water has been shown to help neutralize acidity in the body, which can lead to better hydration and improved digestion. By restoring healthy minerals like calcium, magnesium, and potassium, this filter makes your water healthier while maintaining an ideal pH balance.
Comparison with Express Water vs. Traditional RO Systems
Choosing between a tankless RO system like the Express Water 600 GPD and a traditional tank-based system can be tricky. Let’s break down the differences to help you understand why the Express Water system might be a better choice for your home.
Tankless vs. Tank-Based Systems
The most obvious difference between these systems is the storage tank. Traditional RO systems come with a bulky tank to store filtered water, which can take up a lot of space under your sink. On the other hand, the Express Water tankless system is compact, saving valuable storage space.
Additionally, tankless systems provide filtered water on demand, meaning there’s no waiting around for a tank to refill. In contrast, tank-based systems can run out of water, especially in busy households. For families that use a lot of water throughout the day, the 600 GPD capacity of the Express Water system ensures a constant supply of clean water.
Water Waste Comparison (2:1 Pure to Drain Ratio)
A common complaint about reverse osmosis systems is the amount of wastewater they produce. Traditional RO systems can waste up to 3-5 gallons of water for every gallon of purified water, which is not exactly eco-friendly.
The Express Water system improves on this by using a 2:1 pure-to-drain ratio, meaning it wastes only one gallon of water for every two gallons of purified water. This makes it a much more sustainable option, especially if you’re concerned about water conservation.
Speed and Water Output
Traditional systems are often slower when it comes to producing water. Since they rely on a tank to store water, they may struggle to keep up with demand. The Express Water tankless system stands out for its speed, producing up to 600 gallons per day.
This means you’ll never have to wait for your water to be filtered. Whether you’re filling up a glass or preparing water for cooking, you’ll always have filtered water at the ready.
Customer Reviews and Feedback
Customer reviews are one of the best ways to get an honest look at a product, and the Express Water Tankless RO System has received overwhelmingly positive feedback. Here’s what users have to say:

Common Complaints and Issues
While most reviews are positive, there are a few common complaints. Some users experienced leaks during installation, which were usually due to fittings not being tight enough. Double-checking all connections during installation should resolve this issue.
Another frequent point of feedback is the plastic taste that some users experienced after first setting up the system. This is common with new RO systems, and flushing the system a few times typically resolves the issue.
Final Verdict: Is Express Water Tankless RO System Worth It?
After exploring the features, benefits, and customer experiences, you might be wondering: Is the Express Water Tankless RO System worth it? The answer depends on your needs, but for most people, this system offers excellent value for its price.
