To be safe, it is recommended to use lead-free brass valves or those that meet the requirements set by the Safe Drinking Water Act (SDWA). It's also important to note that if a brass valve is being used to regulate water from a contaminated source, the valve itself would not make the water safe to drink.
yes brass properly made to the standard for potable water are perfectly safe provided the water running through them is to the standards for potable water.
The lead content of these standard brass parts is 2.5% to 3.7%. Brass shape products are produced from Alloy C3604B with a lead content of 1.8% to 3.7%. These brass alloys do not meet the low lead requirements as stated in the Safe Drinking Water Act.

Lead-Free Brass Fittings
The lead-free fittings are identified by a double groove on the face of the female fitting (see Fig. 1) and on the inside of the male fitting (see Fig. 2).
It is true that in areas where water is less acidic, brass fitting is better. But in areas where water is acidic or easily contaminated, plastic fittings are better. Hot soils effect brass fitting as they tend to corrode easily. When they corrode it starts wearing away, it can cause failure at any time.
Typical brasses used in these applications are alloys of Cu, Zn, and Pb with small amounts of other metals such as Sn (see List of Additives). The Pb content is typically 2 to 8 %, and these can be marketed as “lead free”. In true no-lead brasses, Bi and Sb are used in place of Pb (http://www.envirobrass.com).
Brass products in plumbing systems can allow high levels of lead to leak into the drinking water. This is true even in brand new buildings.
Due to its composition, food-grade brass can resist oxidation and corrosion caused by water and food fluids, making it ideal for water systems, valves, and fittings.
Safety and Hygiene:
Brass faucets are comparatively hygienic for both kitchen and bathroom environments, providing safe spaces for all ages.
Brass provides reasonable strength and toughness, good corrosion resistance and ductility, (as well as a significant thermal expansion coefficient) at temperatures up to 400°F.
Copper bottles have strong health benefits and kill germs really well, making them perfect for people who want to improve their overall health. Brass bottles, which are made with both copper and zinc, offer a range of health advantages for a lower cost.

Decent Corrosion Resistance: While not as corrosion-resistant as stainless steel, brass can withstand most normal water conditions without significant issues. 5. Lead Concerns: Historically, brass fittings contained lead, which could leach into drinking water.
Until recently, most in-line brass components contained toxic lead, many of which are still presently in use. Corrosion of brass components leads to the release of metals to drinking water. The primary factors of brass corrosion in drinking water are temperature, alloy composition and water chemistry.
Lead is added to brass to make it easier to machine into smooth surfaces for valve seats, threads, and other fittings. Alternatives to lead have had some problems with corrosion in the past.
They are corrosion-resistant and durable, which makes them well-suited for use in plumbing applications where they contact with water. Additionally, many brass valves are made with low-lead or lead-free alloys, which reduces the risk of lead leaching into the drinking water.
Brass water is safe to consume only in limited measures consciously, consult the experts to understand based on your current health conditions before the inclusion of brass water as a ritual.
You must have seen brass utensils in your Grandma's kitchen. Also known as pital, this alloy is often used in religious ceremonies. While it is okay to serve food in brass, the metal easily reacts with salt and acidic foods, when it is heated. Hence, cooking in such utensils must be avoided.
Do faucets contain lead? Most faucets purchased prior to 1997 were constructed of brass or chrome-plated brass, which contain up to 8 percent lead (the main metals in brass are copper and zinc).
All brass fittings and valves shall have the manufacturers name or trademark integrally stamped or cast on it. Another marking identifying the “no-lead” brass alloy, e.g., 'NL', shall be cast or stamped on the fitting or valve.
Corrosion
Also, when brass is submerged in water, its natural zinc qualities get lost. In return, this causes the metal to become weak, which eventually causes pipe decay.
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.
Both bronze and brass may include small proportions of a range of other elements including arsenic, lead, phosphorus, aluminium, manganese and silicon.
C693 Lead-Free Brass has excellent dezincification corrosion resistance and excellent stress corrosion cracking resistance. One if its unique features is that it is corrosion resistant to chemicals found in water and gas. It has high strength equivalent to stainless steel.
