5-Year Assessment of Internal Sprinkler Piping Condition Explained

In accordance with NFPA 25, an assessment of the internal condition of sprinkler piping is to be conducted at a minimum frequency of 5 years. These assessments are critical to identify the “presence of foreign organic and inorganic material.” Foreign materials can cause obstructions and corrosion to pipes and sprinklers. This article will explain the 5-year assessment of the internal condition of sprinkler piping requirements, and how our team of experts can help ensure your system complies with these NFPA 25 requirements. If and when you're ready, you can request an inspection with Ahern for your earliest convenience.

Assessments & Obstruction Investigations

NFPA 25 provides guidance to conduct assessments of internal piping conditions. It is important to note that NFPA 25 makes a distinction between an “assessment” of the internal condition of piping and an “obstruction investigation.” 

1. Assessment of Internal Condition of Piping – NFPA 25 suggests several methods to conduct an assessment, such as the following:

• Opening a flushing connection at the end of a main and the end fitting of a branch line. A visual inspection for “the presence of foreign organic and inorganic material” can then be conducted through these pipe openings. 
• Other technologies capable of examining the internal condition of system piping.

2. Obstruction Investigation – If “foreign organic or inorganic material” is found during the assessment of internal pipe condition, or if any conditions listed in section 14.3 of NFPA 25 exist, an obstruction investigation is to be conducted. Obstruction investigations start with internal examinations at additional points in the piping network. If material is found that is sufficient to obstruct pipe or sprinklers, a complete flushing program is to be conducted. Refer to chapter 14 of NFPA 25 for additional details of obstruction investigation requirements.

Importance of 5-Year Assessment of Internal Sprinkler Piping Condition 

Fire protection systems safeguard more than your building, which is why having these 5-year assessments performed is critical to ensure your systems function as designed in the event of an emergency. Regular inspections are required by NFPA 25, and it is crucial to ensure your system is properly maintained to avoid costly repairs or failures.

If your fire sprinkler systems are not receiving periodic inspection and testing, there is a high chance they may not function properly, if at all.
