That's a pretty great deal for only $150 in my opinion. I'll never need 100GPD but I suppose it couldn't hurt to have more than enough flow. It's looking more and more like I'll need to repurpose one of our basement rooms into a fish room. Or should I say aquatic plant garden? I think the latter. 😉
I added $60 in modifying mine to 200GPD.
This just gets the Brute cans filled in a more timely manner.
It does put the 2nd shower/bath out of commission for most of the day but he// that's only one day every two or so weeks.
RO is not for everyone, it involves re-mineralizing to reach desired GH & KH values.
The benefit is knowing exactly what's in your water 100% of the time.
I no longer re-mineralize the brute cans, dose the tanks independently as I see fit keeping KH very low.
I'm not recommending RODI, just sharing how I handle it.
Since I have this down to a routine and a science now I would not go back.
I never bothered with the small storage tank etc... since I produce water only every 2-3 weeks.
The RO is cheap after you purchase 3 Brute cans with casters to move them around!
