Ispring Reverse Osmosis System

What contaminants does the iSpring RCC7 remove from water?

The system removes up to 99% of over 1,000 harmful contaminants including PFAS, lead (up to 98%), arsenic, asbestos, chlorine, fluoride, calcium, sodium and other dissolved solids. It reduces total dissolved solids by 80-90% and eliminates hard water minerals that cause scale buildup. The reverse osmosis membrane filters particles down to 0.0001 microns, ensuring comprehensive purification that exceeds bottled water quality standards.

How much space is required for installation under the sink?

The system measures 18cm length x 15cm width x 27cm height and weighs 12.47kg. It fits under most standard kitchen sinks but requires adequate clearance for filter changes and connections. Before purchasing, measure your under-sink space to ensure proper fit. The compact design accommodates most installations, but some users with limited space may need to install in adjacent cupboards.

What water pressure and temperature requirements does this system have?

The system requires incoming water pressure between 45-70 psi for optimal performance, though it can be configured for special requirements. Operating water temperature must be between 4.4-37.8°C (40-100°F). Maximum supported total dissolved solids should not exceed 750 ppm for municipal water or 2000 ppm with pre-treatment. These parameters ensure proper membrane function and system longevity.

How often do the filters need replacement and what do they cost?

Filter replacement schedules vary by usage and water quality. Typically, stages 1-3 require replacement every 6-12 months, the RO membrane (stage 4) every 2-3 years and the final polishing filter (stage 5) every 12 months. Replacement filters are readily available with part numbers FP15, FG15, FC15, MC7 and FT15. Filter packs are available for convenient bulk purchasing, reducing long-term maintenance costs.

Can this system be connected to ice makers or coffee machines?

Yes, the system can supply purified water to ice makers, coffee machines and other appliances using iSpring ICEK output line connections. This expands the system's utility beyond the included faucet, allowing multiple points of use throughout your kitchen. The 75 gallon daily capacity easily supports additional connections whilst maintaining adequate flow rates for all applications.

Is the system suitable for well water or only municipal water?

The RCC7 is designed specifically for municipal tap water treatment. Well water typically requires pre-filtration to remove sediment, bacteria and other contaminants before reverse osmosis processing. iSpring offers whole house water solutions specifically designed for well water applications. Using this system with untreated well water may damage the membrane and void the warranty.

What warranty and support comes with the iSpring RCC7?

The system includes a 1-year money-back guarantee, 1-year manufacturer warranty and lifetime technical support from iSpring's USA facility in Alpharetta, Georgia. This comprehensive coverage ensures long-term peace of mind and assistance with installation, maintenance, or troubleshooting. The company has provided quality support for over 15 years, with many customers praising their responsive customer service.

How difficult is the installation process for DIY users?

Installation is designed for DIY completion by most users with basic tools and following included instructions. The package includes clear written guides, instructional videos and all necessary components including PTFE tape and water leak detector. Most installations take 2-4 hours depending on plumbing configuration. The patented top-mounted faucet design simplifies the process, though users uncomfortable with plumbing connections may prefer professional installation.
