I set up 4 "rain barrels" around the house which I told my wife was for use in water planets and the yard. I'm going to pick up a 5th to keep in the garage which will have the stated use of emergency water supply. The Sawyer mini water filters seem to be pretty good. My water barrels are inverted with a garden hose size outlet tapped into 1 of the bung hole caps. Has anyone tried to adapt the Sawyer mini to a 3/4 garden hose thread? I'm thinking that with a series of adapters I can just connect one to the barrel I'm using and filter the water as I drain it from the water/rain barrel.
