Fire sprinklers are a must-have in any building, large or small. They are designed to provide life-saving protection from fires and save lives. While typical fire sprinklers have a lifespan of 35 to 40 years, they do expire and need to be regularly inspected and maintained.

In fact, survey data indicates that 63% of buildings inspected had at least one defunct fire sprinkler head or other safety concern! So when should you replace your fire sprinkler heads?

Let’s take a look at the facts.

Fire Sprinkler Heads: The Expiration Date You Need To Know

The National Fire Protection Agency (NFPA) recommends replacing your fire sprinkler heads every 10 to 15 years. This is due to wear and tear on the system over time; if it hasn’t been properly maintained then chances are your sprinklers could be operating less than effectively.

Regular inspections and tests help to ensure your system is functioning optimally so that you can rest assured that it’s providing maximum protection for your home or business.

In addition to regular inspections and replacement, there are other maintenance steps you can take to keep your fire sprinkler heads in optimal condition.

For example, you should check for corrosion or rusting on the exterior of the head, as well as any obstructed lines or fittings within the system itself.

You should also make sure that any paint used near the head is flame retardant; otherwise, it could potentially set off false alarms or even interfere with its ability to detect heat and activate during an emergency situation.

Finally, remember that not all types of fire sprinklers are created equal; while some types may only require maintenance every five years or so, others may need more frequent attention in order to stay up-to-date with current regulations and standards.

Be sure to consult your local building codes before conducting any maintenance work on your fire suppression system!

How Can I Tell If My Fire Sprinkler System Is Working Properly?

The best way to know for sure is by having a professional come in and inspect it for you. They can check for any signs of damage or wear and tear, replace any outdated parts, make sure all connections are secure, test the pressure within each section of the system, and make sure everything is running smoothly.

It’s also good practice to check your smoke detectors periodically; these are an important part of any fire sprinkler system since they alert people when there is smoke in the area so they can evacuate quickly before any flames break out.

While most systems will last up to 35-40 years without needing major repairs or replacements, it’s still best practice to have an expert come in annually just in case something needs attention!


Fire sprinkler heads are essential pieces of equipment for protecting homes and businesses from fires, but they do expire after some time passed without proper inspection or maintenance checks!

Regular inspections and tests help ensure that your system is functioning optimally; if it hasn’t been properly maintained then chances are your sprinklers could be operating less than effectively.

Remember also that different types of systems require different levels of attention; consult local building codes for specific details about what type of maintenance schedule is best for your particular situation!

With regular inspection and maintenance, you can trust that your fire suppression system will always provide maximum protection when needed most.
