Does any of you manufacturers make this in a small system?

It's a water purifying process that re-uses the same bit of DI resin over and over, gets water down to higher levels of purity than we need, but doesn't use up resin, so could be cost effective in the long run...Depends on unit cost I guess.

So I guess that's a 'no' then.

Looks like it might be expensive and not suitable for hard water?

Thanks for that, I was unaware of the hard water issue.

The water where I live is so hard it'll beat you up and steal your wallet
