Are Fire Sprinklers
Required Everywhere?
As the debate continues for
the use and implementation of fire sprinkler systems, there are some things
that home inspectors should know. Currently only the entire state of California require
sprinkler systems in all single family and larger residences. Many individual
municipalities are requiring residential sprinkler systems. Multiple units and
commercial buildings already have the requirement in place in most areas. Some
materials approved are steel pipe, black iron, PEX, copper, and CPVC (orange in
color). I see mostly orange CPVC. Probably due to cost and ease of
installation, however there are some issues associated with its use. Some
products may degrade CPVC and must be considered before employing it. Some types
of caulk, fire stopping products, mold / antimicrobial products, certain types
of pipe tape, certain thread sealants, some leak detector fluids, coated pipe
hangers, and one type of waterproofing. Any of these products may degrade CPVC
and should not come in contact with it. Fire sprinkler pipes need to be secured
to ensure they do not uplift under pressure. Where are the areas that fire
sprinklers are not required according to NFPA 13 – 903.3.1.1.1 & 2;
