Frequently Asked Questions
How often do I need to replace the iSpring RCC7AK filters?expand_more
The replacement schedule varies by filter stage. Typically, the pre-filters (stages 1-3) need replacement every 6-12 months, the RO membrane (stage 4) every 2-3 years, and the post-filters, including the alkaline filter (stages 5-6), every 6-12 months. iSpring offers various filter kits for convenience.
Is the alkaline filter (pH+) on the iSpring RCC7AK necessary?expand_more
The alkaline filter is not strictly necessary for water safety but is included to remineralize the water and balance its pH after the RO process. Many users prefer the taste of alkaline water, finding it smoother and more refreshing than standard RO water.
What does 75 GPD mean for my water system?expand_more
GPD stands for Gallons Per Day, indicating the system's production capacity. A 75 GPD rating means the RO membrane can produce up to 75 gallons of purified water per day. This is generally sufficient for most households, providing enough water for drinking and cooking without significant delays, even with typical usage.
Can I install the iSpring RCC7AK system myself?expand_more
Yes, the iSpring RCC7AK is designed for DIY installation with features like quick-connect fittings and a top-mounted faucet design that simplifies under-sink access. Clear manuals and step-by-step videos are provided to assist, though basic plumbing knowledge is beneficial.
What common contaminants does the iSpring RCC7AK filter out?expand_more
This 6-stage RO system is certified to reduce a wide range of contaminants, including TDS (93-98%), PFAS (96-99%), chlorine (95-99%), lead (>98.9%), fluoride (>97.4%), asbestos (>99.7%), and over 1,000 other impurities.
Does the iSpring RCC7AK waste a lot of water?expand_more
Yes, like most reverse osmosis systems, the iSpring RCC7AK does produce wastewater. Reports suggest it can waste up to 4 gallons of water for every 1 gallon of purified water produced. This is a common characteristic of RO technology.
My filtered water has a plastic or sweet taste. What should I do?expand_more
A slight plastic or first-use taste is common and usually dissipates after an initial flushing period. Ensure the system has been flushed according to the manual's instructions (typically cycling several tanks of water). If the taste persists, check filter seating and consider if the alkaline filter needs replacement or if there are other installation-related issues.
What are the dimensions of the iSpring RCC7AK unit?expand_more
The system itself is relatively compact but requires space for the filters, tank, and tubing. While specific dimensions can vary slightly, it is generally considered a bulkier under-sink unit and may require careful planning for installation in smaller cabinets.
