A residential sprinkler system monitors temperature, not smoke. When the air around a sprinkler head reaches its trigger temperature, only the heads closest to the flames open, releasing 10 to 25 gallons of water per minute. That fast, targeted response knocks down heat, flames, and smoke before they can spread, protecting your family and limiting property damage. Because each head works independently, the rest of your home stays dry.

Yes—any time water hits drywall, flooring, or furniture, there’s a chance for damage. However, the moisture from a sprinkler head is far less destructive than unchecked flames and smoke. Sprinklers release 10 to 25 gallons per minute, while a fire hose can unleash hundreds. The controlled flow helps contain the blaze quickly, so any cleanup costs are a fraction of what full‑scale fire restoration would run.

Blanket size depends on what you want to protect. A 3-by-3-foot model is suitable for small stovetop flare-ups, a 6-by-6-foot blanket can wrap around a person, and a 10-by-10-foot option covers larger areas, such as a mattress or workbench. When in doubt, choose the larger size; extra coverage gives you a better chance of smothering a fire quickly.

Install at least one smoke and carbon monoxide detector on every floor, including the basement and garage. Place smoke detectors 10 feet from cooking appliances to reduce false alarms, and keep CO detectors high on the wall or ceiling, following the manufacturer’s instructions. Bedrooms and hallways leading to sleeping areas also need coverage so you’ll hear the alarm even when you’re asleep.

Installing a home fire sprinkler system delivers vital safety and financial benefits. It suppresses fires immediately, protecting lives while minimizing property damage. Homes equipped with these systems record 87% fewer deaths, 27% fewer injuries, and 70% less property damage, and they also gain up to an 8% reduction in insurance premiums while increasing overall home appeal and long-term protection.

The NFPA model codes and the International Residential Code require fire sprinklers in all new one‑ and two‑family homes, but enforcement varies by state and local jurisdiction. Check with your state fire marshal or building department to learn what applies in your area. Even when sprinklers aren’t mandated, installing a system adds a crucial layer of protection and can lower insurance premiums.
