When RO Is the Wrong First Purchase
The first purchase is the test, not the chrome faucet.
Platbookmapper is an Amazon Associate. If you buy through an Amazon link on this page, we earn a commission. The link is a product, not the county map.
Why this comes up
The first purchase is the test, not the chrome faucet. If the test is fine, you may not need RO at all.
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 Water test kit when that is the job in front of you. If the test is fine, you may not need RO at all.
The limit
Test the well before you buy a system. Reverse osmosis treats a drinking tap. It does not fix every well problem, and it is not a survey tool.
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.
