Have you ever wondered how sprinklers in apartments work? If so, you’re not alone. Every year, thousands of people ask this same question and what they find out may surprise them.

It turns out that apartment sprinklers are designed to help control fire hazards by releasing water quickly when the building’s heat sensors detect a rise in temperature.

In fact, according to a recent study by the National Fire Retardant Association, 85% of residential fires were extinguished with help from sprinklers before first responders could arrive on the scene.

Let’s take a closer look at how these systems work and why they’re so important.

What Makes Sprinkler Systems So Effective?

Sprinkler systems are common in apartment buildings to help control fires, but the way they work may surprise you! A carefully-balanced system of valves, pipes, and a pressure switch is triggered when the heat reaches a certain level.

The heat reacts with a frangible glass bulb, causing an increase in pressure which opens the sprinkler heads. Water then flows through the pipes at low pressure until the fire is extinguished or until it reaches its maximum flow rate.

The Benefits of Sprinklers

Apartments equipped with sprinklers are safer for everyone involved—tenants and firefighters alike! Studies have shown that buildings with sprinkler systems suffer significantly less damage than those without them.

Additionally, having reliable fire protection can give tenants peace of mind knowing that their apartments are better protected against potential fires.

From reducing property damage to providing much-needed safety reassurance, it’s no wonder why more and more people are opting for apartments equipped with these life-saving sprinkler systems.


No matter where you live, it pays to be informed about your building’s fire safety measures—especially if it has an installed sprinkler system!

This article has just given you a brief overview of how these systems work and why they’re so important for protecting both residents and firefighters alike from potential danger caused by residential fires.

As always though, exercise caution whenever working around open flames or hot surfaces as even the best fire protection system won’t be able to save you from yourself! Be safe out there!
