An FPS is a closed, non-circulating system that can become a stagnant reservoir of untreated water. These systems are ideal environments for microbiologically influenced corrosion (MIC). MIC accelerates buildup and leaks in fire sprinkler piping.
Buildup and tuberculation nodules can affect  the
designed hydraulic performance of the system. In an emergency, nodules can break
off and plug sprinkler heads. Leaks cause property damage and lost production.
Buildup symptoms include dark colored water with a rotten egg odor on flushing
or draining, interior tuberculation blockage, positive biological test, or pin-hole
leaks.
Herc Products has developed
their MIControl® Program
to provide system owner's with data and solutions to, step-by-step, cost
effective decisions and the service to carry them out.
