I find the post very helpful because I'm interested in buying a filtration system. Rainsoft equipment is 6, 000$ and the reverse osmosis system is not included. On top of that, you have to buy 2 different tanks (one for iron removal and one for manganese) which takes up more room in the mechanical room. Kinetico seems to be offering the same system with only one tank and says you have to replace the interior after 5 years (cost of 500$). Guarantee can be carried over or you can take the system with you. However, plumbers are not cheap and have the company to move it probably costs the same. Also, there might be new technology a less expensive price and will just as per-formant if not more (like computers and phones). Thanks for the info. MJL
