It has been three days and no response from you concerning the dangers you outline in this quote.
The key here is the first four words of this section, “Metal water piping system(s)”.
The code is addressing metal water piping SYSTEMS not integrated systems. A metal piping system will be complete 100% metal with nothing nonmetallic installed. Once any type of nonmetallic pipe or fitting is used the system is no longer a metallic system but becomes a mixed system. This is nothing more than common sense and nothing that I made up. It is written for anyone to read and comprehend.
I have respectfully asked for your opinion as to how this integrated piping system is more dangerous without response. I am always eager to learn something new and now is your chance to teach so please explain.
Should a pex piping system be installed according to your statement above then it would be a danger to the end user should they decide to use brass mixing valves unless these valves were bonded. I suppose that having a water pipe grounding clamp installed on the spout of the mixing valve would accommodate this.
A pex water piping system in most cases use brass fittings. Will these need bonding also? $4 for a clamp and about a $1.50 per foot for the copper to bond with, shucks the bonding will cost more than the piping system.
Once again I am respectfully asking for you to give us your opinion of why this is such a danger. I have used the code itself in my comments so please if you would use code references to show me the dangers you outline.
Public safety is the forerunner of my life. My job as a code enforcement official demands that I have my facts straight so please help me to understand the error of my ways.
Lets discuss the statement you make about me making something up concerning bonding of “metal” water systems. Here is the code section in question;My point was, there is nothing mentioning 100 percent, as you made that up. If anything, broken sections of mixed metallic and nonmetallic pipe become more dangerous than this imaginary 100 prevent number you dreamed up. Don't give me your interpretation of code. I read code and code alone. Save your fairy tales for someone else.i know better
250.104(A)(1) General. Metal water piping system(s) installed in or attached to a building or structure shall be bonded to the service equipment enclosure, the grounded conductor at the service, the grounding electrode conductor where of sufficient size, or to the one or more grounding electrodes used. The bonding jumper(s) shall be sized in accordance with Table 250.66 except as permitted in 250.104(A)(2) and (A)(3).
