Is brass a NSF 61?

In general, Waterworks Brass products are covered by section 8 of ANSI/NSF 61.

How do I know if my brass fittings are lead free?

The standard lead-free brass fittings are made with marine-grade DZR brass and are currently acceptable under the Safe Drinking Water Act, but will be restricted to non-potable water applications as of 2014. The lead-free fittings are identified by a double groove on the face of the female fitting (see Fig.

Does NSF 61 mean lead free?

Section 3.5 of NSF/ANSI 61 precludes the use of lead as an intentional additive in wetted materials and components of products, with the exception of brass and bronze meeting the definition of “lead free” within the specific provision of the U.S. Safe Drinking Water Act (SDWA).

Is there lead in brass plumbing fittings?

Brass is an alloy made mostly of copper and zinc, but when they made these faucets and valves from the late 1970s to 2014, the brass could also have up to 8% lead in it.

Can you make brass without lead?

ECO BRASS is a lead-free (Pb-free) high performance copper alloy with superior properties to currently used alloys. ECO BRASS has high strength, excellent machinability, exceptional wear resistance, good creep properties, and superior corrosion resistance.

Is lead free brass Food Safe?

By law all brass must now be lead free IF it is an item generally used for potable water. Some exceptions are components made for heating systems but not also used in potable water, and toilet parts (if you can even find any made of brass.) I would not eat brass food.

What is NSF 61 Annex G?

NSF/ANSI 61 is comprised of leachate testing criteria for the evaluation of pipes, fittings and solvent cement to ensure that all potential contaminants, not just lead, cannot be extracted from them and leach into potable water. FlowGuard® CPVC products have earned the NSF 61 Annex G certification.

Can you get lead poisoning from brass?

Brass devices in plumbing systems can create serious lead-in-water problems. Summary: A new research study highlights problems with some brass products in plumbing systems that can leach high levels of lead into drinking water, even in brand new buildings — and suggests that such problems may often go undetected.

Does lead leach out of brass?

Water sitting for several hours or overnight in a brass faucet can leach lead from the brass faucet interior which may produce high lead levels in the first draw of drinking water.
