Gravity Filter for a Hunting Cabin
Cabins sit empty, and filters dry out.

Why this comes up
Cabins sit empty, and filters dry out. Plan on spare elements if the cabin sits for months between visits.
What to check on the map first
County GIS lines are assessment maps. They are not a survey, and a product will not redraw them.
Open Platbookmapper and choose the state. The directory sends you to the county viewer. Match the parcel ID before you trust a pin on an aerial photo.
A tool that matches the job
Shop the Berkey replacement filters when that is the job in front of you. Plan on spare elements if the cabin sits for months between visits.
The limit
Filter water you hauled from a known tap, or water a lab has already tested. A steel crock does not make creek water safe.
Match the parcel ID on the tax bill before you shop for the field kit.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
