There is always a lot of discussion of these materials on the forums.
The 2006 California Plumbing Code ( based on 2006 UPC ) basically allows PEX, but not adopted by certain state agencies.
As far as I know, this is still the status of PEX in San Diego:
As for CPVC, the code grants to local authority the power to approve the use of CPVC, subject to some severe requirements. The plumbing contractor must provide written certification that he will comply with the flushing and worker safety measures of section 301.0 of Appendix I. There is also a provision that a contractor or subcontractor who fails to comply with the flushing, gloves, and ventilation of section 1.2.2 of appendix I, and IAPMO IS 20-2005, shall be subject to penalties.....etc.
Not surprising that I don't see much CPVC being used here either!
It looks like California is considering a more widespread use of PEX. Here is link to a notice that says they are going to prepare an Eniviromental Impact Report for the use of PEX. http://www.documents.dgs.ca.gov/bsc/...2010.31.07.pdf
The letter from San Diego is a little old and was written before the new plumbing code. A quick search on San Diego's website provided some information on the new codes. http://www.sandiego.gov/development-...fchanges07.pdf
someone has landed the job of provideing the
state of california with an Eniviromental Impact Report
I would love to know who got to do this report and how much
that is going to cost the state of Cali-forni-cation to have it done.....
a few million dollars probably to tell explain to the lawyers in the
legislature how great the stuff is and how it wont hurt the environment....
The REAL environmental impact wont be from the actual PEX
pipe but from all the failures and flooding disasters that will surely
arise over the next 10 years.....
I would think it would be best if this Eniviromental Impact Report
was actually performed by the insurance companies in the State
who will eventually get stuck holding the bag with the enormous
lawsuits, litigations, and property damages that will eventually arise
throughout the state...over the next 10 years........
All they really got to do is look at Las-Vegas and Minnesota. to see what
the eivironmental impact will be like for them..
my bet is Governer Arnie or some of his freinds are
being bribed handsomely by the people that make all the
different forms of pex to get pex ram-rodded through... ..
I'll be back.......
Of course Copper is the absolute best...
but it is the most expensive way to do a home...
probably adds about $ 700 ---$1500
to the cost of any plumbing system..
(ballpark estimate )
money is the only thing that matters $$price price price....
followed probably by CPVC.... which is pretty good all in all
then along comes a whole bunch
of untested- un-proven new Pexes you can choose from....
but only the WIRSBO pex seems to be the best
all the others have a long string of disaster stories
across the USA...
and probably a few to come to your town soon.
This debate has gone on for quite a while here
I really hate to stir it up again....
Yes the copper can develope pin holes, but on
average its in a system well over 30 years old
(in our region it has served us well)
You have not run across a failed pex system becasue most
of them are not over 10 years old yet.......
my own personal home was built in 1964 with copper L
and is stil fine.......
I dread the day it finally
does fail in the slab.... I will probably start crying..
but what more can you ask than having a system
last from 1964 to 2007??? thats 43 years and counting
again we dont realy know how long Wirsbo, vanguard,
Kitech, Zurn, or whatver will last
with the chlorine in the water systems and whatever
other inhibitors that they might add to the water some day....
your guess is as good as mine.....
and if we are very lucky...
it will be some other dumb-ass that will
have to change all it out 15 years from now
would you like to be one of the fellows being sued
in the Kitech fiasco in Las Vegas??? 50,000 homes...
In all Honesty....one of the main reasons everyone has gone to PEX
is that pex wont grow legs and walk off a job site after it has been installed....
and the copper has to be guarded
till someone moves into the home...
Copper works well but everyone ignores the water condition problem. Sounds like alabama has no method or willingness to fix the core problem, just employ the symptom fixers.
Another debate of piping choices?

For the record I am certainly not anti copper. Copper installs mean more revenue for the company. As piping systems go however, I personally hold pex to be at least equal and probably superior to copper. Ultimately it is up to the client. I am happy to install either but when they see the cost difference they usually go with the pex. I have a 60 year old ranch house w/crawl space. I have all copper water distribution piping. I have yet to experience my first copper pipe failure. This home was even originally on well water although it hasn't been for at least 25 years and probably longer.
Should it become necessary to re-pipe I will do it in pex.
CPVC is good enough for industrial piping and is qualified for use in fire sprinkler systems. It is certainly adequate for residential water systems.
In addition to tube sizes 1/2" to 2", CPVC is available in Schedule 40 and Schedule 80 Iron Pipe Sizes from 1/8" to 24". I have not seen the pipe sizes, or tube sizes greater than 3/4", sold in the Big Box stores.
FROM THE LINK ABOVE:
Click here to download specification sheet
Corrosion resistant pressure pipe, IPS sizes 1/8" through 24", for use at temperatures up to and including 200°F. Pressure rating (130 psi to 1130 psi) varies with schedule, pipe size, and temperature as shown on page 2 of this specification, and as stated in Harvel Plastics, Inc. engineering bulletin (Product Bulletin 112/401). Generally resistant to most acids, bases, salts, aliphatic solutions, oxidants, and halogens. Chemical resistance data is available and should be referenced for proper material selection. Pipe exhibits excellent flammability characteristics (ULC Listed for Surface Burning Characteristics) and other physical properties. Typical applications include: chemical processing, plating, high purity applications, hot and cold potable water systems, water and wastewater treatment, and other industrial applications involving hot corrosive fluid transfer.
Here is another link:
CPVC piping for potable hot and cold water distribution systems is recognized in all model plumbing codes.
Also, CPVC plumbing pipe is safe for installation in return air plenums; however, the installation must be approved by the local jurisdiction. Even though CPVC is considered a combustible material it will not burn without a significant external flame source. Once the flame source is removed CPVC will not sustain combustion. Testing indicates that water filled CPVC in diameters 3" or less will pass the 25/50 flame smoke developed requirements for non-metallic material in return air plenums. CPVC fire sprinkler pipe tested and listed in accordance with UL 1887, "Fire Test of Plastic Sprinkler Pipe for Flame and Smoke Characteristics," meets the requirements of NFPA 90A for installation in return air plenums.
I have to say I like pex so far. Granted my house is only 2 years old, but this morning I had my pex pipe freeze because some insulation fell out of a fresh air inlet for the house. My plumber told me to put a heater under the pipe and thaw it out. The pipe had expanded a little where it was frozen. After about ten minutes the pex thawed and water started flowing again. I've checked it just a while ago and the pipe looks like nothing had happened. I'm almost certain if it were copper it would have burst. After reading this thread I may come back in 8 years saying pex stinks, but for now it's great.
When CPVC freezes and bursts, it usually runs longways down the pipe and is very hard to detect this until you reconnect and find out the hard way.
When I did busted/frozen water lines this past winter I wouldn't even bother doing anything other than replacing the entire section between fittings where a leak was.
Has a tendency to spread water damage a great deal more because that water will fan out of that longways leak...covering a larger area until the water is shut off.
