Replacing corroded piping is maintenance and if no changes were made during the replacement, no evaluation of the hazards would be necessary while performing NFPA 25 maintenance.

The system is protecting fruit stored in bins in a controlled atmosphere building. The system is rotting out and needs to be replaced, I can't find a specific clause in the codes that say's replace it as it currently is - the problem being a dry grid. To further complicate the problem the original classification was a Class II (fruit in wood bins), today those bins are HDPE - Group A Plastic. With this information would you agree that you can't replace the system as originally installed? Jim Johnston, P.E.
