Water Supply Line and Building Code
Ok, so I received my, rather hefty, copy of the 2006 International Residential Code. I will be ordering a water main installation to the country estate and will have to run the supply line from the main to the house.
According to the code P2904.4 the supply line must conform to NSF 61. The accompanying table would seem to indicate that I can use PEX. However, I see (from the table) that PEX - in several varieties - has standards listed such as ASTM F876, etc...
If I google ASTM F876 it would appear that this standard encompasses NSF 61 which is mainly concerning the health effects of the pipe material.
So, what exactly am I looking for when I go to buy the supply line? NSF 61? ASTM F876? Someother standard that I haven't come across yet?
