What is in the water
Our water filtration coverage in Colorado runs to 370 ZIP codes in 145 cities. Large municipalities buy and treat water at scale and publish an annual quality report for the whole system, so what arrives at the tap is well documented — and the variation that is left is mostly in the pipework between the main and the tap.

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 Colorado
Colorado licenses are issued by the Colorado State Plumbing Board, Division of Professions and Occupations, which publishes a public search you can use before work begins.

What that coverage looks like
Jefferson County holds 109 of the 370 ZIP codes we cover in Colorado, and Denver 67 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.

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.
