What is in the water
Our water filtration coverage in New York runs to 1,215 ZIP codes in 781 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 New York
New York issues no state plumbing license. New York City licenses Master and Journeyman Plumbers through the Department of Buildings; elsewhere in the state it is your own city, town or county. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.

What that coverage looks like
New York County holds 149 of the 1,215 ZIP codes we cover in New York, and New York 149 of those. A supply that large is usually one system with one published quality report; the remaining 34 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.
