How & When To Drain a Fire Sprinkler System

If a fire starts in your building, you count on your fire sprinkler system to protect you and your property. Fire sprinklers play a critical part in protecting buildings from fire-related damage and occupants from harm.

Fire sprinkler systems should detect and control fires, often before the fire department arrives. Proper maintenance helps them function effectively, especially in commercial properties such as manufacturing facilities, healthcare facilities, educational institutions, and other high-risk areas.  

One key part of fire sprinkler maintenance is to regularly drain them. At Kauffman Co. Fire & Life Safety, we want you to understand the best fire sprinkler maintenance practices, including how and when to drain a fire sprinkler system.  

Reasons To Drain a Fire Sprinkler System

Draining a commercial fire sprinkler system is sometimes necessary to make sure it operates correctly. Here are some common reasons you might need to drain your system:

• Routine maintenance: Regular inspections and maintenance keep your fire sprinkler system in top condition. During these inspections, technicians may drain the system to check for any issues or wear and tear.
• System repairs or modifications: If your sprinkler system needs repairs or changes, draining the system may be necessary to make those changes safely.
• Winterization: For seasonal properties or locations that experience freezing temperatures, winterization is important. Draining the system can prevent pipes from freezing and causing damage.
• Renovations or building changes: Renovations can require alterations to the sprinkler system. Draining allows for safe adjustments and keeps the system aligned with the new building layout.
• Post-activation cleanup: After a fire, draining the system helps remove water, debris, or residue left in the pipes, preparing the system for future use.
• System replacement: If the fire sprinkler system needs to be replaced, draining the current system is the first step in the process.

Types of Fire Sprinkler Systems

It’s also important to know what type of fire sprinkler system you have. They come in various types, each needing specific procedures for draining:

• Wet systems: These systems are filled with water at all times. Draining involves releasing the water from the pipes, typically through a main drain valve.
• Dry systems: Filled with pressurized air or nitrogen, dry systems release water only when activated. Draining requires careful management of both air and water parts.

When To Call a Professional

Fire sprinklers are technical. While it might be tempting to try DIY solutions, there are serious risks involved. Draining a sprinkler system involves complex procedures that require specialized knowledge. Incorrect handling and DIY fixes can lead to water damage or system malfunction.

Protecting the safety of the building and its occupants is important, and you may qualify for tax incentives. Professionals have the experience and equipment to manage these tasks safely, while incorrect DIY procedures could put the occupants and building at risk.

General Steps for Draining a Fire Sprinkler System

Draining a fire sprinkler system involves several steps. Here’s a brief overview, but remember to consult a professional for the best results:

• Preparation: Identify the type of system and locate the main drain valve. Professionals will also make sure they have the necessary tools available.
• Draining process: Open the main drain valve slowly to allow water to exit the system. For dry systems, release air pressure first, then release the water.
• Post-draining checks: After the system is drained, technicians inspect it for any leftover water or debris. Then, they make sure all valves are closed properly.
