What is in the water
Our water filtration coverage in Minnesota runs to 298 ZIP codes in 141 cities. A state of both large and small systems is a state where two houses twenty miles apart can be drinking water of quite different hardness and quite different treatment, and the annual report for each is the place that says so.

What this site is
ClearTapCall is a referral service, not a contractor and not a laboratory. We connect homeowners with independent contractors for filtration and treatment installation. Contractors are required to hold whatever credential their state or municipality demands, and treatment equipment plumbed into a supply is often a permitted alteration — ask to see the permit. We carry out no work, we sell no equipment, we test no water, we do not set prices, and we never charge homeowners anything. Nothing here is a statement about the water at any address, and no page recommends a product.Checking a credential in Minnesota
Minnesota licenses are issued by the Minnesota Department of Labor and Industry, which publishes a public search you can use before work begins. The Minnesota lookup also shows bond status and any enforcement action.

What that coverage looks like
Hennepin County holds 150 of the 298 ZIP codes we cover in Minnesota, and Minneapolis 68 of those. A supply that large is usually one system with one published quality report; the remaining 20 counties contain many smaller systems, each with a report of its own.
How a water filtration job goes
Filtration is chosen from a test result, not from a taste. Hardness, iron, sediment and chlorine each call for different equipment, and a cartridge sized for one does nothing for the others. The order is always the same: find out what is in the water, then decide what has to come out of it, then size the equipment for how much water the house actually uses.
What the call asks about water filtration
- Whether the supply is a public system or a private well, because the testing route is different.
- What the water is actually doing — staining, scale, smell, taste, cloudiness.
- Whether there is a test result already, from the annual report or from a lab.
Every Minnesota city we route in
60 cities, ordered by the share of housing built since 2000. Plumbing age decides what the water picks up between the main and the tap. Each page carries that city’s own numbers and the ZIP codes we route there.

Before you call
Filtration starts with knowing what is actually in the supply. The pages above set out which test result points at which kind of equipment.
