Cabin Filters

By: Wolfman
July 22, 2009

I built a system to filter the creek water at our remote cabin in central Idaho. ( the three black tubes in the upper left house the Gravidyns) I store the water in 60 gal barrels then pump it into the house with an RV pump powered by solar pannel and battery.

Cool Clean Water

By: Wolfman
July 22, 2009

These gravidyns supply all clean potable water for two of us for extended stays at our cabin. I use a house filter first to get the chunks out, then the gravidyns. The time of year(muddy creek) dictates how often I have to clean the filters and that only takes a few minutes. I will buy these again.
