Im totally new at this and i have a question that may seem rather...stupid. In an emergency do you just quit getting water from your faucet? Would it be because there is no electricity to pump it through the pipes? Or is it that we would get water but it could be contaminated? Also, would purifcation tablets work as well as a water filter? It seems like they would be much easier. Im starting to stockpile some food, and want to tackle the water issue but just dont know where to start. Any advice would be greatly appreciated.
