It seems to me it would be very difficult to filter without a filter bag or a set of buckets! We also know that most people don’t have a drill or even the right size drill bits. So that’s why we offer pre-drilled buckets for a gravity-feed water filtering system. For this purpose, we drill the bucket and lid to fit a 1/2″ filter shaft. The second thing we do is drill a 3/4″ hole for the spigot.
In this situation you only get (two 2-gallon buckets and lids) that were previously drilled to fit a 1/2″ filter shaft. It also includes a 3/4″ hole for a spigot.
