So far so good! It works,
Water coming out has zero taste. Which is good, because my cities water has a strong chemical odor/taste.
Coffee made with this water has no bitterness. That's another issue with our cities water.
With only one filter candle it is slow however. About 1 liter an hour, When it gets down below 2 liters in the upper bucket it nearly stops dripping. If this became an issue, I would build a second unit rather than add a second filter candle.
For an upcoming project I will show you how I build a rain barrel for under $15.00.
Afterall, who wants to scoop water from puddles.
