We all know that a fire sprinkler system is crucial for fire safety, but few people understand that there are actually different types of sprinkler systems out there. Among the many types available, dry pipe and wet pipe sprinkler systems are two of the most commonly used for commercial properties.
Since each type of fire sprinkler system has advantages and disadvantages, it’s essential to understand the differences before choosing the right option for your property’s needs. To help you choose, we will explain how either type works and the pros and cons of each. We’ll also discuss a handy fire sprinkler head shut-off tool that you can use to protect your property from water damage.
Wet Pipe Fire Sprinkler Systems
Wet pipe fire sprinkler systems are by far the most common type, especially in office buildings, hotels, and commercial properties. As the name implies, water is always present in the pipes with these systems, allowing it to be discharged immediately when the system is activated.
Pros of Wet Pipe Systems
Faster Response Time
Since water is already in the pipes, the system can release water the second a fire is detected.
Simplicity
Wet pipe systems are easier to maintain than other types because they have fewer moving parts and potential points of failure, making them a very dependable option.
Low Maintenance Requirements
Like any sprinkler system, inspections and regular maintenance are both still required, but wet pipe systems generally require less maintenance than dry pipe systems.
Cons of Wet Pipe Systems
Risk of Freezing
The water in the pipes can freeze in cold environments, including indoor cold storage facilities. Not only could this damage the system and pipes, the sprinkler system would be ineffective in the event of a fire
Increased Water Damage Risk
If a sprinkler head accidentally activates, water damage can occur quickly, as it is stored in high pipe volumes.
This is why keeping a Shutgun Fire Sprinkler Shut-off Tool with every fire extinguisher in the building is important. The Shutgun provides a simple, affordable, and effective way to stop the water flow in case of accidental activation or even if a fire sprinkler system continues discharging water after it has successfully extinguished a fire.
Dry Pipe Fire Sprinkler Systems
Unlike wet pipe systems, water is not actually stored in the pipes with dry pipe fire sprinkler systems. Instead, they are filled with compressed air or nitrogen. When a sprinkler head activates, the pressure change caused by the gas quickly escaping releases a valve, allowing water to flow into the system and out through the activated sprinkler.
Pros of Dry Pipe Systems
Ideal for Cold Environments
Since the pipes don’t contain standing water, the risk of freezing is greatly reduced. This makes them a far more suitable option for unheated warehouses, industrial buildings, parking garages, cold storage facilities, and basically any location where the temperature could drop below freezing at any point during the day.
Reduced Risk of Water Damage
Since the pipes don’t store water, there is a lower risk of accidental discharge or misfire, which will cause significant water damage. Still, it can happen after water has flooded the pipes due to a misfire, which is why it’s still a good idea to keep the correct types of Shutgun tools on hand.
A good idea is to pick up a Custom Shutgun Case containing the exact number and type of tools your facility requires.
Cons of Dry Pipe Systems
Slightly Slower Response Time
Since water has to travel through the pipes to the sprinkler heads, there is a delay between sprinkler activation and water discharge. While it is minimal, seconds matter when it comes to fires.
Higher Installation and Maintenance Costs
Dry pipe systems require more components, like air compressors and specialized valves, so professional installation and maintenance costs tend to be higher.
Reducing Water Damage with the Shutgun
As mentioned, both wet and dry pipe systems carry a risk regarding costly water damage. Wet pipe systems can instantly release large amounts of water, while dry pipe systems still allow water to flow continuously after they are triggered.
No matter which type of system you have, investing in the right Shutgun tool can save you tens of thousands of dollars in water damage. Rather than waiting for first responders, you can deactivate any sprinkler head quickly and easily. If you have “tamper-resistant” fire sprinkler heads, invest in the Institutional Shutgun, while facilities with concealed or recessed fire sprinkler heads should possess the Concealed Head Shutgun.
Final Words
Both types of fire sprinkler systems play a critical role in fire safety. However, each has unique drawbacks that must be carefully considered. If you’re unsure what you need, you can speak with a fire sprinkler professional about your facility’s requirements.
