Clumps of corroded material are visible throughout the pipe. “This is tuberculation, and on the inside of the pipe, (it) builds up and builds up and builds up like a clogged artery,” she said.

As the result, tuberculation of the pipes have caused mounds of iron-oxide to form inside the pipes that have restricted water flow, Fink said. That’s especially concerning when it comes to ...
