WATER SOFTENER AND WELL WATER FILTER COMBO
Complete Protection - the RKIN Combo Water Treatment System uses a comprehensive approach to filtering water.
It filters iron, sulfur and manganese while preventing hardness build-up throughout your home.
Filters Out Iron, Sulfur, and Manganese
Does your water smell like rotten eggs? Do your sinks & toilets have orange staining? You and your family deserve the best quality water and expect that it be delivered at each faucet whenever needed.
RKIN Filter System is the answer to your problem water to reduce Iron, Sulfur and Manganese.
Softer Skin & Healthier Hair
Eliminate contaminants in the water that can be harmful to your body. By filtering chemicals such as hardness, iron, sulfur, and manganese, you can avoid the drying effects of chemicals, promoting softer skin and healthier hair.
Better Tasting Food & Water
With our whole house water treatment system, you can savor the purity in the kitchen.
Filtered water enhances not only the water that you drink but also the quality of the food that you eat. Upgrade your cooking by using cleaner and healthier filtered water.
Why Use a Water Softener
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.
Prevent Hardness Build-up
Extend the life of your plumbing and household appliances by preventing scale build-up. Appliances that use soft water will last longer and run better. Why? Because water heaters, washing machines, and dishwashers using hard water can wear out 30% faster.
Comes Install-Ready
All our products come install-ready with minimal assembly required.
RKIN whole house water systems are manufactured in the USA and are made to be installed easily without needing professional help. However, we do recommend hiring a plumber if you are not mechanically inclined.
INDEPENDENT LABORATORY TESTING
TEST ONCE AND BE ABSOLUTELY SURE YOU ARE PURCHASING THE RIGHT WATER SYSTEM FOR YOUR HOME
Water test by a certified independent laboratory will help you determine exactly which water issues are present and identify the proper equipment needed to treat them. For most people on well water Metals and Minerals test is sufficient. If you are noticing yellow coloration of water or staining, a tannins test is also required.
