Water based fire protection systems are static, have few moving parts and need to work if and when there is a fire. These reasons alone require some means to make sure the system will work properly when called to service. The National Fire Protection Association (NFPA) has developed guidelines – NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. Most states, Connecticut and Rhode Island included, have adopted NFPA 25 as a code requirement. Besides the code requirements, your insurance carrier may apply a premium credit for an operational fire protection system. Your overall peace of mind and protection from liability claims for an inadequate fire protection system are at stake. Regular inspection, testing and maintenance ensure your liability is minimized.

P&J Sprinkler Company performs NFPA 25 inspection and testing per the latest code requirements. The reporting software we use clearly informs you of your system’s health.

The maintenance services required for water based fire protection systems are based on NFPA 25 requirements and frequencies, along with manufacturer’s recommendations. These maintenance frequencies range from annual to 10 year intervals.

P&J Sprinkler Company can guide you through the maintenance requirements applicable for your system.

The life expectancy of sprinkler heads ranges from 5 to 75 years. NFPA 25 has guidelines on which types of sprinklers need to be tested or replaced and how often. Unless the fire sprinkler head is damaged, painted, or corroded it can be tested by an approved testing laboratory like Underwriters Laboratories (UL) to determine the useful life expectancy.

P&J Sprinkler Company can help determine what types of sprinkler heads you have in your system and determine if they are due for testing, replacement, or if still suitable for use.

We have seen wet pipe fire sprinkler systems that are over 100 years old in buildings. The length of time a fire sprinkler system lasts is dependent upon the type of system (wet versus dry), condition of the piping, and the type of occupancy. Dry pipe fire sprinkler systems can also last 50 to 100 years if they were properly installed and maintained.

We can evaluate your system to determine its condition and estimate its life expectancy.

Since 1984, P&J Sprinkler Company has installed hundreds single family home fire sprinkler systems. We have a variety of experience with new and retrofit, design and installation of fire sprinklers in homes. The cost for single family home fire sprinkler systems varies for factors such as water supply, home design, finishes, and the type of sprinkler heads used.

You can easily find information on-line that states single family home fire sprinklers cost between $1.35 and $1.65 per square foot. These costs are based on large single-family subdivisions with hundreds of tract homes, supplied by city water and located in other parts of the United States, such as the South or Southwest. These costs are NOT realistic for the single family home market in Connecticut and Rhode Island. These types of subdivisions rarely happen in New England. We can provide firm written proposals and estimates for your home system once we gather all the details. Please call us at to start a conversation.

Yes, but with limitations and exceptions. PEX piping made by Viega and Uponor can be used in single family residential sprinkler systems. CPVC plastic piping made for fire sprinkler system installation can be used in single family, apartments and hotels up to four stories, and light commercial applications. There are very specific guidelines of where and how plastic piping can be used.

P&J Sprinkler Company has used PEX and CPVC plastic piping for fire sprinkler system installations and we will guide you through the best use of these materials.

Wet pipe fire sprinkler systems are most common. System water is pressurized in the piping and will discharge immediately from the sprinklers when they activate. Wet pipe system must be installed in areas where the temperature will not drop below 40 degrees Fahrenheit.

Dry pipe fire sprinkler systems do not have water in the piping. Instead, there is air or nitrogen pressure in the piping. When a sprinkler head activates, the air or nitrogen pressure escapes and the dry pipe valve releases water in the piping system to the sprinkler head. Dry pipe systems are used in areas where water can freeze, such as unheated attics and outside covered spaces.

P&J Sprinkler Company can help you determine the best system to use for the particular application.

It seems that if the piping system is dry then it would not rust or corrode inside. It is true that a dry pipe fire sprinkler system piping is not supposed to have any water in the piping. Dry pipe fire sprinkler systems are used in buildings where there is a possibility of freezing, often in attics. Realistically there is water or moisture in dry pipe fire sprinkler systems, moisture generated by the air compressor, residual water in piping after system trip tested, or because of poorly pitched piping for drainage. This water combined with oxygen in the piping creates the rust and corrosion.
P&J Sprinkler Company has installed, serviced, and maintained many dry pipe fire sprinkler systems. We have applied techniques to remediate corrosion in dry system piping by eliminating excessive water accumulation and utilizing nitrogen generator technology to eliminate oxygen in the system.
