Lockhart is an unincorporated community in north Orange County, settled back in the 1890s along the old US 441 corridor between Orlando and Apopka. Because it grew up as an unincorporated area, a fair share of its older and larger lots run on private wells rather than a municipal supply. Those wells draw from the Floridan Aquifer, commonly 100 to 400 feet down, and when one fails, there is no city main to fall back on.
Central Florida's limestone makes that water hard and mineral-rich, so scale builds up inside pumps, pressure tanks, and check valves over the years until something fails. A submersible scaled into its casing has to be freed patiently rather than forced, and that is how we handle it.
