Is it permissible to serve both an automatic dry sprinkler system and a dry automatic standpipe via the same dry pipe valve?

As long as the combined system capacity is not more than 750 gallons and if there is a separate standpipe control valve, it would be acceptable per NFPA. Separate dry pipe vales, entirely separate systems, would be a much better practice.

you need to meet the combination riser requirements from NFPA 14. I dont think you would be able to meet them on one shared valve. Leave a Reply. |
