Q & A Plumbing
| |||||||||||||||||||||||
When repairing old faucets I've seen illustrations that call for a dab of "plumber's grease". Is this stuff food grade? What about other chemicals used in the installation of fresh water systems.? ...Perplexed Plumber, 12/1996
In any package of material that might come in contact with potable water there should be a label from whatever testing agencies are recognized by prevailing building code enforcement authority. In our neck of the woods that would be IAPMO or ANSI. Any packaging around here will carry the labels "UPC/IAPMO file #1282" and or "ANSI/NSF 61". The ANSI testing procedures are presented in their document, "Drinking Water System Components, Health Effects (partial revision of ANSI/NSF 61-1992 (sections 4 and 5)) ."
To be honest, I have never seen this document. It costs $115. I assume it concludes toxic agents are excluded from use in potable water systems. Just a guess. From what I've heard, ANSI is the most widely recognized testing standards organization in the USA.
The NSSN is the organization that publishes ANSI info. their site is at http://www.nssn.org/plweb/index2.html
As far as I know these standards do not address the long term exposures to low levels of these chemicals. I have a request into several experts in these matters and will update this file as soon as they respond...
Synco Chemical Corporation in Bohemia, N.Y. makes "Super Lube" which appears not only to be an excellent lubricant for plumbing fixtures, but the manufacturer claims that it is highly lubricious, very inert, non-toxic, on-corrosive, stays where you put it due to superior adhesion, does not attract dust or other contaminants, and can be used between -65 deg. F and +650 deg. F.

UPC 1210.1 does not list copper as an acceptable material for gas piping.
Other codes don't have this restriction but you have to check with the supplying
utility. Sulfides in odorants can deteriate copper. Codes aside, you should
check with the utility to find out about the composition of their gas and
its effect on the copper.

I'd prefer to have the drain and water supply lines come up through the floor and the pedestal instead of the wall for a better appearance. My home is on a crawl space on is a one story ranch style house. Is there a drain made particularly for this problem?
There are polished brass tail pieces and traps for open plumbing.
> If not, can I run a straight drain to the crawl space an put my trap there?
Not by code. Code says 24" max. tail piece and no "S" trap. Enforcement is up to the local agency. Your building department might allow an "S" trap for a pedestal. You have to check with them.The practical consisderation is by not taking your vent off above the weir of your trap you will siphon your trap dry and it will stink...rk
