New Jersey (via the Uniform Construction Code and the National Standard Plumbing code) specifically prohibit some plumbing items. Then how come I can go into the local big-box stores and purchase them? Two items that I regularly see in stores, as well as in the field, including brand new construction, include the following:
* Flexible traps and tailpieces – specifically prohibited by the NJ UCC. These items can be manipulated to allow misaligned pipes to mate – when plumbing errors (in new construction) occur, and in rehab installations where a new sink drain does not align with the old drain.
* Self-piercing and needle type saddle valves (used primarily for water supplies to refrigerators and the like) - which are prohibited by NSPC.
Why can these items be purchased? Who is supposed to enforce these standards on a store? Most importantly, why would a licensed plumbing contractor (some of the installations I have seen were installed by the same) even use these? (Because it is easier, I know that.)
These items can also be easily obtained on the Internet.
I guess if you are not part of the solution you are part of the problem – so I am going to write to some of these stores and see the responses that I get.
