Legionella is a bacterium that lives and proliferates in natural and artificial aquatic environments at temperatures ranging between 5.7°C and 55°C and standing up to acidic and alkaline environments.
New s.84AW is approved for use with drinking water; the specific ball design avoids water stagnation and the spread of bacteria in the system.
