24% of housing has gone up since 2000.

Free to homeowners in Londonderry — the contractor pays us for the introduction, you never do.

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.Londonderry in numbers

What the annual report tells you
Every public system publishes a consumer confidence report. It covers the supply as it leaves the system, which is not the same as the water at your tap after it has crossed your own pipe.
Point of use or whole house
A cartridge under one sink and a whole-house unit at the service entry solve different problems. Which you need follows from the test result, not from the price.
