Water Softeners & Water Treatment in Merritt Island, FL
Most of Merritt Island is on City of Cocoa water, but some properties, especially up north, run on private wells. The fix depends on which you have.
Merritt Island water in short
Most Merritt Island homes get City of Cocoa water: about 6.7 grains per gallon and chloramine. Some properties, especially in north Merritt Island, use private wells, where smell, iron and salt are bigger issues than hardness. Check your water bill. If you don't have one, you're likely on a well, so test it first.

On city water, Merritt Island looks like the rest of central Brevard: City of Cocoa water, moderately hard at about 6.7 grains per gallon, disinfected with chloramine. A right-sized softener handles scale and spots; catalytic carbon handles the chloramine taste; under-sink RO gives you drinking water.
North Merritt Island is more rural, and some homes there use their own wells and septic systems. If you're on a well, the Florida Department of Health in Brevard County recommends testing every year for bacteria and nitrate and every three years for lead. A rotten-egg smell, orange stains or a salty taste each need their own fix. Hardness is usually the last thing to treat, not the first.
