CPVC Piping Limitations
CPVC Piping Limitations
(OP)
I am trying to sub this new installation to a sprinkler contractor but something caught my attention.
The contractor stated that CPVC piping may be used in lieu of black pipe where applicable.
The job in questions is an existing restaurant/bar in Elizabeth, NJ.
In 18 years I have never seen such thing. Can some one explain if possible?

I've used CPVC in existing restaurants. When listed for such use its the best since our guys are often in there after hours (8-11PM, when the restaurant closes) and one can cut it to fit.
Check the listing for blazemaster : http://w

6.3.6.1 - Table 6.3.6.1 lists CPVC (i.e. Blazemaster).
Blazemaster is listed for "Light Hazard" per NewtonFP's post above.
NFPA 13 (2002) Blazemaster is permitted as follows:
6.3.6.2 "Pipe ... listed for light hazard occupancies shal be permitted .... in ordinary hazard rooms of otherwise light hazard occupancies where the room does not exceed 400 square feet."
Again, I'm quoting the 2002 edition, so maybe I'm out of date.

I'm sure an expert witness for the state of New Jersey can figure this one out, using the excellent advice posted above.
RE: CPVC Piping Limitations
I want to know why an expert opinion advisor for the State of NJ and NICET Level 3 ITM who wants to stamp drawings did not already know this.
RE: CPVC Piping Limitations
does this sound more like a design spec, as in where you can use a certain material if allowed??? an either or situation
RE: CPVC Piping Limitations
Anyways, can we all proceed with the conversation. I have never seen anyone using CPVC in a existing restaurant in all my years of experience.
Typically is used in new residential or existing residential. Very little commercial applications I seen.
I guess I should bid on the job as long as the town allows CPVC to be used.
Thanks everyone else.

If the restaurant is wood construction, make sure you look closely at the requirements to use only specially listed sprinklers with CPVC exposed in combustible concealed spaces.

For example Jersey City does not allow cpvc piping. If you get approved you are lucky.

I am NOT calling out NJ1 with this post (please do not get defensive); I hope everyone in our industry looks in the mirror as they read my words. It just seems like a huge majority of the people in our industry try to complete the various job tasks without research. How do people think the knowledgeable people in our industry gained the knowledge? Time and effort; many many late night hours reading and studying pertinent documents!
CPVC is one of the best examples......we all see systems which have been installed incorrectly, but the use of CPVC is off the charts when you compare what is installed verses the CPVC pipe manufacturer's installation guidelines. NFPA clearly states that CPVC components SHALL be installed in accordance with the CPVC pipe manufacturer's installation guidelines, but WAY too many companies have employees who are either unaware or blatantly ignore the manufacturer's installation guidelines.
I am not anti-CPVC (as some blog participants have implied or concluded)........as long as it is installed properly!
