What is in the water
Our water filtration coverage in Connecticut runs to 287 ZIP codes in 199 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 Connecticut
Connecticut licenses are issued by the Connecticut Department of Consumer Protection, which publishes a public search you can use before work begins. Connecticut issues a P-1 plumbing contractor license and a P-2 journeyperson license, among several narrower classes.

What that coverage looks like
Capitol Planning Region County holds 106 of the 287 ZIP codes we cover in Connecticut, and Hartford 36 of those. A supply that large is usually one system with one published quality report; the remaining 13 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 Connecticut city we route in
51 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.
