The Difference Between Wet & Dry Sprinkler Systems

As a business owner, it’s important to protect your investment. Your company’s space houses many valuable items, including expensive tools and important documents. A commercial fire sprinkler system can safeguard these resources in case of a fire and ensures you’re compliant with local safety regulations. Here are two popular sprinkler models to choose from.


In a wet sprinkler system, the pipes feeding the heads are filled with water. If the system is activated, it’ll discharge water to put out a fire. Wet pipe sprinkler systems are commonly used because they’re cost-effective and easy to maintain.

One drawback of these systems is that the pipes may burst in temperatures below 40 degrees

Fahrenheit, causing property damage. Even if you don’t live in a cold location, this may be relevant if parts of your business experience chillier conditions, like refrigerated areas.


In a dry fire sprinkler system, the pipes feeding the heads are filled with pressurized nitrogen or air. The air prevents water from flowing into the pipes, eliminating the risk of frozen, damaged pipes.

In case of a fire, the pressure in the pipes decreases, and a valve opens so that the water can reach the heads and put out the fire. Dry systems are costlier and more complicated to maintain. However, if parts of your business are subject to below-freezing temperatures, this is the safer option.
