Wooden letter blocks spelling the word “MYTHS” on a rustic wooden background.

Myth #1: “If one sprinkler goes off, they all go off.”

Fact: Fire sprinklers are designed to activate individually when they detect high heat from a fire. In most home fire situations, only one sprinkler is needed to control the flames. Hollywood movies may show every sprinkler drenching an entire building at once, but that’s far from reality.


Myth #2: “Sprinklers cause more water damage than fire.”

Fact: Sprinklers use far less water than the fire department hoses. A single sprinkler head typically releases 10–25 gallons per minute, while a firefighter’s hose can release 150+ gallons per minute. That means sprinklers minimize both fire and water damage.


Myth #3: “Fire sprinklers are too expensive to install.”

Fact: The cost of installing residential fire sprinklers is often comparable to other upgrades like new flooring or granite countertops. Plus, many insurance providers offer discounts for homes with sprinklers—helping offset installation costs over time. Most importantly, the safety value is priceless.


Myth #4: “Smoke alarms provide the same protection.”

Fact: Smoke alarms are essential, but they only alert you to danger—they don’t fight the fire. Sprinklers respond immediately to heat, often extinguishing or controlling the fire before it spreads. Used together, smoke alarms and sprinklers provide maximum home protection.


Myth #5: “Sprinklers will go off accidentally and flood my home.”

Fact: Residential sprinklers are highly reliable and tested to prevent accidental activation. The chance of a random sprinkler discharge is estimated at 1 in 16 million. In reality, you’re far more likely to experience a major house fire than a sprinkler malfunction.

 

Final Thoughts

Residential fire sprinklers are a smart, effective way to protect your home in Kent, WA. They stop small fires from becoming big disasters, save lives, and limit damage. Don’t let myths keep you from the peace of mind that comes with real fire protection.
