Homeowner and Building Manager Tips

What can you do to address concerns in your home or building?

Legionella is responsible for >90% of waterborne outbreaks caused from plumbing, according to the Centers for Disease Control and Prevention (CDC). In most cases, the treated water delivered to homes all over the U.S. is required to meet federal and state standards for drinking water. Once the water enters a home's plumbing, a different environment exists where the water quality can degrade over time and the plumbing becomes vulnerable to the growth of these bacteria.

Homeowners and building managers have a critical role in protecting the health of their occupants:

Maintain proper water heater temperatures to prevent growth of Legionella. A water temperature of 130–140°F can kill many harmful germs, but also increases the risk of scalding. If you set the water heater above 120°F, take extra precautions to mix cold and hot water (using thermostatic valves) at the faucet or shower to avoid scalding. This is especially important if young children, older adults, or other people at increased risk of scalding live in your home.
