USE OF HAMP IN SPRINKLER SYSTEM

Question asked by franco.sutto on Jan 31, 2017

Good evening. I am mailing from Italy. After reading a lot of comments, blogs, etc., I am asking if there is an officiaI interpretation of NFPA about use of hamp + sealing compound to seal pipe joints in wet sprinkler systems. This is normal practice for our National code.

Someone can help me?
