What it is
The iSpring RCC7AK-BN is a comprehensive under-sink solution designed to tackle the common complaint of flat-tasting reverse osmosis water. By integrating a remineralization stage, this system adds back essential minerals like calcium and magnesium, raising the pH level to create a more natural spring water profile. The inclusion of a transparent first-stage housing is a practical touch, allowing you to visually confirm when the sediment filter is reaching its capacity without having to disassemble the unit. Installation is notably improved over older models thanks to a patented top-mounted faucet design. This allows you to secure the hardware from above the counter rather than struggling with a wrench in the tight, dark space behind the sink basin. With a 75-gallon per day capacity and NSF 58 certification, this system is robust enough for large households that prioritize both safety and the specific mouthfeel of alkaline water.
Ravvy AI insight
While the 75 GPD rating is generous, real-world flow rates depend heavily on your home's water pressure. We recommend this specific model over the standard RCC7 because the remineralization stage prevents the slightly acidic profile typical of pure RO water, which can be harsh on some people's stomachs and copper plumbing.

How to get the most out of it
Flushing the System
After the initial installation, ensure you drain the first two full tanks of water. This clears out any carbon fines and prepares the filters for optimal taste performance.
Ownership tips
tip
Check Your Water Pressure
This system relies on house pressure to push water through the membrane. If your home pressure is below 45 psi, consider adding a booster pump to ensure the storage tank fills efficiently.
care
Visual Inspections
Use the transparent housing to your advantage. If the white sediment filter looks dark brown or gray before the six-month mark, your local water may have high sediment, and you should change it early.
Frequently asked questions
Does this system remove fluoride?
Yes, the reverse osmosis membrane is highly effective at removing fluoride, typically reducing it by over 97 percent alongside other contaminants like lead and arsenic.
How often do the filters need to be replaced?
The three pre-filters should be replaced every 6 months. The RO membrane and post-carbon filters typically last 1 to 2 years, while the alkaline filter is usually replaced annually.
Can I connect this to my refrigerator ice maker?
Yes, you can purchase an additional fridge connection kit. This allows you to send the purified, remineralized water to your refrigerator for both ice and chilled water.
What is the purpose of the alkaline stage?
Standard reverse osmosis can make water slightly acidic. The alkaline stage adds back healthy minerals like calcium and magnesium to balance the pH and provide a fresher taste.
