Would like some opinions before I spend the cash - considering buying a 100 GPD 5-stage RO DI filtration system with chloramine filters, similar to what the aquarium hobbiests use to filter their water. Makes very pure water. This is not a whole house system - those are too expensive, just a 100gpd system. I am presently on a well but will be switching over to "city" water shortly. That means chlorine and who knows what else? The other option is to buy bottled water which is not regulated so who knows where it is coming from and how pure it is - a spigot in back room of store or warehouse for all we know. Other than the initial outlay for the small system and minimal cartridge change outs due to volume of water going through it, seams a good option.
Are you moving house/apartment etc or just the water supply ? Because here, our service has just been put on a water meter, so future bills will be for exact household useage. Which for the small RO system I bought a couple of months ago, would work out expensive to run i.e. of every 100 litres in, I'd get about 20 litres of RO water.
So if it's just changing the supply, then an RO system, but use the well supply pumped, then the return/waste back to the well ? Then it'd be the "ideal".
I'm having to think up ways of rain water harvesting, so that I can keep enough water made as RO, but so that I can also return the waste to a barrel for garden use.
The domestic utility supply here, only really needs sorting out as RO, because we're in a very hard water area. Now I don't know about what it'd be like in your neck of the woods from a point of hardness, calcium hardness, magnesium salts etc, but it's that that causes a "harshness" to taste with my meads, the chlorine/chloramine etc doesn't seem to be an issue.
So it's really all about whats actually happening with your change of supply and how the new supply is costed/priced/charged etc.....
