[Greenbuilding] [BULK] Sprinklers-and PEX

[Keith Winston]

I suppose if this is an optional sprinkler system, it probably doesn't

(it's orange) for code-required installs.

However, PEX is usually installed with fittings that throttle down it's 
flow considerably. Also, it would be quite expensive at the sizes 
sprinkler systems are often installed at...
