Product Q&A
3 QuestionsQ: What is so "lead" about this 3/4 1170M2-US valve compared to the " lead free 3/4 LF1170M2-US" model? Do some folks use the 3/4 1170M2-US on domestic hot water because the lead content is so little? I ask because this model 3/4 1170M2-US on some sites are considered lead free also.

Verified Reply- PexSupply Staff"Lead-free" models contain less than 0.25% lead, which is the maximum lead content allowed by code in California and Vermont. A similar law is scheduled to go into effect nationally in January 2014 (only applies to new installations).
My use of the 3/4 1170M2-US valve is in a solar hot water circuit in Phoenix, AZ that is used primarily for hot water for bathrooms (showers and sinks) in a house where the youngest resident is over 65. Thus even when that hot water is used to wash dishes and glassware, any minuscule amount of residual lead will not cause retardation in young, developing brains. The particular application required a valve with threaded fittings for installation after all piping was soldered as well as for no-solder replacement should the originally-installed valve fail.
Looks like the lead free one is made of brass, instead of bronze. I don't know how much lead is in bronze.
only thing I can think of is maybe the leadcontent in the solder used to sweat it to the piping it is being installed/ connected to. There might be a small amount in an internal valve seat pressed or sweated inside the unit. Any further question of lead used in the construction of or assebly of the item should be directed to the manufacturer. Realistically though, this is only used on the hot water side of your piping system. Unless you are using the hot taps to drink from or cook with, there should be no issue in the first place.
