(Apartment Prepper) A water purifier is one of the most important pieces of gear you will ever need for emergency preparedness. As my long-time readers know, I use a Berkey Light water purifier and have been using it on a daily basis for years. I lived in many neighborhoods in Houston that seemed to have sketchy water pipes as the tap water often came out brownish. The water also had an unpleasant chlorine after taste. The property management said it was not their issue; their pipes were fine, the Water District has control over water quality. After speaking with some of the neighbors, I learned this was a common complaint: the water coming out of their tap contains a lot of sediment and tends to be murky.
