Can someone please explain the ins and outs of using an RO unit?
1. Do you need to buy anything else besides the RO unit and replacement media cartridges? I read something about a flush kit, what is this and how do you use it, do you need one?
2. Can you set up your RO/DI unit on a non-dedicated faucet ie. have it attached to your faucet, but be able to flip a switch and bypass the unit?
3. Do the RO/DI units generally run continuously 24/7 or do you just turn them on and off when needed? If you only use them when needed, do you have to run your water to clear the lines before each use?
4. Should you replace the cartridges on a set timetable every so many months, or after every so many gallons of water, or only when the media runs out? Is a TDS metre necessary or just useful?
5. Based on ease of use, maintenance, and cost of cartridges, and capacity of the unit, and time/gallons between cartridge changes, which unit is recommended? I see Kent as an often-mentioned brand, is this one to go with?
6. I have seen RO units for household (kitchen) use, are these OK to use as a source of water for your tank as well?
7. Are the RO/DI units easy enough to install for someone who is not a handyman?
