        Why use an RKIN water softener

        Why Use a Water Softener

        The mineral build-up, or scale, can occur in plumbing and household appliances when your water is hard. Solid deposits of calcium carbonate can form when hard water is heated. This scale can reduce the life of appliances, raise the cost of heating your water and clog pipes. Long-term movement of hard water through a pipe results in scale buildup. This can gradually close up the pipe and lower your water pressure.

        Why use an RKIN water softener and conditioner

        Prevent Hardness Build-up

        Extend the life of your plumbing and household appliances by preventing scale build-up. Appliances that use water will last longer and run better. Why? Because water heaters, washing machines, and dishwashers using hard water can wear out 30% faster.

        How it works 1

        Multi-Stage Carbon Filter

        Stage 1 - KDF Media. Creates a bacteriostatic environment using copper and zinc alloy which helps with the removal of chlorine and heavy metals.

        Stage 2 - Catalytic Activated Carbon Bed. Designed to remove organic contaminants and disinfectant by-products such as chlorine and chloramines.

        Stage 3 - EvenFlow Bed. Innovatively designed to maximize water treatment by substantially increasing contact time with the water filtration media.

        Frequently Asked Questions

        How often does the RKIN salt-based water softener require salt replenishment?

        RKIN CS series salt-based water softeners proactively monitor water usage and regenerate when needed. This "metered" approach ensures maximum efficiency for salt and water usage.

        The exact regeneration schedule and salt replenishment requirement will depend on your water hardness and total household water use.

        The water softener will regenerate at least once every seven days to keep the media within the system in a top-performing state.

        What can I do with the mobile app?

        Legacy View mobile app makes setting up and monitoring your RKIN Water Softener easier than ever. A free download of the phone app is available for your iPhone or Android device.

        • Conveniently view all valve settings and status
        • View estimated salt remaining(water softener only)
        • Easily change valve settings
        • View current water usage information
        • Graphically view water usage history
        • Start a regeneration or backwash cycle from your phone or tablet
        • Better understand the purpose of the settings and how your system is working

        Do I have to use the mobile app?

        No, the mobile app is not required. All the settings can be updated directly from the Water System's control board.

        The mobile app does make the setup quick and easy.

        The Bluetooth module on the valve can be disabled, and the mobile app can be deleted from the phone after the initial setup.

        Who installs my RKIN Water System?

        RKIN ships direct from the factory, saving you over 60% of the standard retail cost. Our products' user-friendly design makes installation easy with or without professional help. However, if you're not mechanically inclined, we do recommend hiring a plumber to help with installation.
