The title says it all: where is the five gallon mark on a standard Home Depot orange five gallon bucket?
If I recall correctly there are a few protrusions near the top on the exterior of the bucket. I think the 5 gallon mark is just under the lowest protruding "ring". Might want to double check that if accuracy matters and exactly 5 gallons is a life or death situation for some reason.I actually tested this once using a milk jug but I can't remember exactly where the line ended up. I do remember it being lower in the bucket than I thought it would.
