Water Security at Home
Water is the most time-critical gap. You can manage three weeks without food. You get three days without water. Jeff started here, and most people should too.
What's your water priority?
3 questions. Jeff will point you to the right solution.
What's your main water concern?
“Water is the one I'd sort first. You can last weeks without food but only days without water — and a burst pipe or a boil notice is a when, not an if. A gravity filter is about the cheapest insurance there is.”
— Jeff, SelfSufficientNow
