What is in the water

Our water filtration coverage in Iowa runs to 150 ZIP codes in 74 cities. A state of many small covered places is a state of many small water systems, and a system serving a few hundred connections can differ sharply from the one in the next town on hardness, iron and treatment.

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 Iowa

Iowa licenses are issued by the Iowa Plumbing and Mechanical Systems Board, which publishes a public search you can use before work begins.

What that coverage looks like

Polk County holds 62 of the 150 ZIP codes we cover in Iowa, and Des Moines 55 of those. A supply that large is usually one system with one published quality report; the remaining 17 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 Iowa city we route in

13 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.
