The ICC Annual Meeting in Minneapolis will be
the deciding grounds for whether residential sprinklers are mandated in the
International Residential Code. It looks to be an interesting meeting this
September.
The most commonly used steel pipe for sprinkler systems is black steel pipe. Copper tubing is another piping material listed for sprinklers in NFPA 13. Also, plastic pipe (namely, CPVC and PEX tubing) is permitted for certain types of sprinkler systems.
Plumbing
Codes and Standards have been all about protection of
public health and safety. This has been accomplished by providing a safe,
potable water supply. In
water reuse, we are introducing non-potable water into water closets and
urinals. You need to ask if we are still maintaining an adequate level of
safety.
