Professional Fire Safety Solutions

Established Fire Sprinklers in Springfield IL

F.J. Murphy & Son, Inc. has been at the forefront of delivering top-notch fire sprinkler systems since 1968, catering to the increasing demand in Central Illinois. Over the years, our commitment to providing the best fire sprinkler solutions has expanded to both the public and private sectors. With statutory requirements for fully functional fire sprinkler systems in most buildings today, we have witnessed a growing adoption, even in single-family residential homes. Over 110 Illinois Municipalities now mandate the installation of fire sprinklers in all new construction projects. The importance of fire sprinklers lies in their life-saving capabilities, detecting and automatically extinguishing fires at their source. Unlike traditional methods, fire sprinklers offer immediate response, preventing loss of life and property destruction. They outperform smoke detectors by not just notifying about a fire but actively working to control it.

Some may propose substitutes like using different building materials or varying drywall thickness during construction as “trade-offs” for fire sprinklers. Yet, the absence of fire sprinklers means that, in the event of a fire, everything inside, including contents and occupants, might be reduced to ashes while the structure itself remains standing. Relying solely on fireproofing the structure can essentially transform the interior into a large furnace.

F.J. Murphy & Son, Inc. ensures the best fire sprinkler services for buildings seeking optimal protection, emphasizing the unmatched benefits of this life-saving technology. Reach out to us today.

Fire Sprinkler Parts & Devices

Discover the intricacies of fire safety with F.J. Murphy & Son, Inc., a leading provider of quality fire sprinkler parts and devices. Our extensive range encompasses precision-engineered components, ensuring the reliability and effectiveness of every fire sprinkler system.

Air Compressors & Maintenance Devices

Air compressors and maintenance devices play a pivotal role in optimizing the functionality of fire sprinkler systems, and at F.J. Murphy & Son, Inc., we take pride in offering top-quality solutions. Air compressors are essential for maintaining appropriate air pressure levels within dry pipe sprinkler systems, ensuring rapid response when needed. Our precision-engineered maintenance devices monitor and regulate the condition of the system, from inspecting valves to detecting potential issues, guaranteeing that each component operates seamlessly. These critical components enhance the reliability and longevity of the fire sprinkler system.

All Piping Devices

With fire sprinkler systems, the intricate network of piping devices is the backbone of safety, and at F.J. Murphy & Son Inc., we prioritize excellence in every component. From robust pipes to meticulously crafted fittings, our piping devices ensure the seamless flow and distribution of water or antifreeze throughout the system. Precision-engineered valves regulate the release of water when temperatures rise, guaranteeing a swift and targeted response. Coupled with air compressors for dry pipe systems, these devices contribute to the efficiency and reliability of our fire sprinkler solutions.

Backflow Preventors

Backflow preventers are crucial guardians within fire sprinkler systems, playing a pivotal role in maintaining the integrity of the water supply. At F.J. Murphy & Son, Inc., our top-of-the-line backflow preventers ensure that water flows in one direction only—outward to the sprinkler heads. This prevents contamination of the water source, safeguarding against backflow that could compromise the system’s effectiveness. These precision-engineered devices act as a barrier, mitigating the risk of polluted water re-entering the clean water supply.

All Valves

Within the fire sprinkler system, valves manage the flow and control of water to ensure optimal functionality. At F.J. Murphy & Son, Inc., our valves are designed with precision to guarantee the reliability of every fire protection setup. Main control valves regulate the overall water supply. Deluge valves unleash water when triggered, particularly useful in high-hazard areas. Check valves prevent the unwanted reversal of water flow, maintaining the pressure needed for swift and effective response. These valves collectively form a comprehensive network that provides precision and reliability to the sprinkler system.

Scheduled Inspections

Our technicians will inspect the systems to maximize dependability and assure full compliance with the local authority having jurisdiction (AHJ), typically your local Fire Department. The inspections also assure full compliance with National Fire Protection Association (NFPA) codes and your insurance company.

Regular quarterly fire sprinkler inspections are a crucial aspect of maintaining a safe and compliant environment. These inspections are mandated by regulatory authorities and industry standards to ensure that fire sprinkler systems are in optimal working condition. Conducting these inspections on a quarterly basis helps identify and address potential issues promptly, ensuring that the system is ready to respond effectively in case of a fire emergency. This proactive approach not only enhances safety but also helps organizations comply with legal requirements, creating a secure and protected space for occupants.

Our fire sprinkler services are provided by well-trained NICET experts who understand fire sprinkler systems inside and out. Don’t hesitate to contact us!

Fire Sprinkler Systems

F.J. Murphy & Son, Inc. stands at the forefront of ensuring safety with state-of-the-art fire sprinkler systems. Our company is dedicated to crafting reliable solutions that protect lives and property. We deliver advanced fire protection, making us a trusted name in safeguarding communities.

Wet Pipe Systems

The wet pipe sprinkler system is the most common, characterized by the constant presence of water within the sprinkler piping. Activation occurs when the temperature at the ceiling reaches a critical point, causing the glass bulb or fusible link in a sprinkler to break, emitting water through the affected sprinkler head. Known for their reliability and cost-effectiveness, wet pipe sprinkler systems should be the first consideration when selecting a fire protection system. If all areas where the piping is located are conditioned to 40°F (4°C) or higher, the risk of freezing diminishes, making the wet system the preferred choice.

Dry Pipe Systems

Dry pipe systems share similarities with wet pipe systems but feature a critical distinction: the pipe is not constantly filled with water. Instead, water is held behind a dry pipe valve, typically situated at a distance from the sprinklers. Activation occurs when the ceiling temperature rises, breaking the glass bulb or fusible link in the sprinkler. However, there’s a delay in water availability as air is released initially, reducing pressure and prompting the dry pipe valve to open. This delay limits the system’s size to minimize water delivery time. This system is ideal for unconditioned spaces where maintaining a guaranteed temperature is challenging.

Glycol Systems

In fire sprinkler systems, a mixture of water and an active antifreeze component prevents freezing, a principle akin to its use in cars and HVAC systems. Commonly, these antifreeze solutions contain either propylene glycol or glycerin mixed with water at specific ratios. However, a concern arises as both propylene glycol and glycerin are flammable substances that can ignite at higher concentrations. Ensuring proper mixing proportions is crucial, yet challenges persist as the varying densities of water and antifreeze cause natural separation over time due to gravity.

Backflow Prevention (CCDI)

Backflow preventers, also known as Cross Connection Device Inspectors (CCDI), are an integral component of plumbing systems that safeguard the quality of our water supply.

Murphy & Son, Inc., we are certified to test these devices, ensuring that they function correctly and protect the integrity of your water source. In Illinois, it is crucial to have a licensed plumber who is certified as a CCDI to conduct these tests, ensuring that your water remains free from harmful substances and contaminants. Our service is necessary to maintain the safety and health of our communities. By having our professionals test your backflow preventers, you can have peace of mind that your water supply remains clean, preventing potential health hazards and costly remediation efforts.

Fire sprinklers are an important part of safety for homes and businesses, providing a crucial line of defense against fires. At F.J. Murphy & Son, Inc., we understand the significance of these systems and the peace of mind they offer to homeowners. As you explore our range of services, you might encounter questions about fire sprinklers that are not immediately addressed.

We firmly believe that a well-maintained and properly functioning fire sprinkler is crucial for any residence, as it can mean the difference between a minor incident and a major disaster. Your safety is our top priority, and we are here to assist you every step of the way.

How do fire sprinklers work?

Automatic fire sprinklers are individually heat-activated and attached to a network of piping with water under pressure. When the heat of a fire raises the sprinkler temperature to its operating temperature (usually 155-165 degrees F), a solder link will melt or a tiny liquid-filled glass bulb will shatter to open that exact sprinkler, releasing water and sounding an alarm. By acting automatically at the origin of a fire, sprinklers prevent a fire from growing to a dangerous size.

Do sprinklers go off accidentally?

It is possible for a sprinkler to discharge accidentally, but this is an extremely rare occurrence in systems that are properly maintained. Records indicate that only 1 in 16,000,000 sprinklers per year will open accidentally.

Don’t fire sprinklers cause widespread water damage?

Fire department hoses typically discharge ten to a hundred times more water than that discharged by sprinklers. Since only the sprinkler closest to the fire is activated to immediately extinguish the fire, the total amount of water damage is usually very limited. Fire and smoke damage is also limited: in buildings with a fully functional sprinkler system, one or maybe two sprinkler heads put out most fires quickly.

How do I find out if I'm required to have fire sprinklers?

Building codes and insurance companies detail where and when sprinklers are required for life safety, and property protection. NFPA codes cover the design, layout, and installation of the systems themselves. A licensed fire protection designing contractor can help you find out about any specific requirements that apply to you.
