Lead. ITS A FUCKEN ACCUMULATIVE POISON
It builds up inside you. Little by little.
Just like DDT and mercury and strontium 90
Over here there was a tv campaign to encourage people to discard the first few mls of water from their tap for drinking because Some places in the world only pay lip service to expected standards of lead level in tapware
So you can quote me all the New Legislation you like
(I am told that you can drink a little foreshots as well but I don't see many trying it)
And I am a plumber so somewhat informed (latin = plumbum = worker of lead)

Thanks, but this wasn't my question.
I asked whether someone got some experience with those red brass fittings made in China.
How to identify red brass at first sight, the colour is brighter, shiny. Hit a reducer, it rings like a bell while copper will give a round, melower sound.

Thanks Sam, I wish I could from here in the middle of nowhere :crying-yellow:
lets look at the facts.
water is water.
ethanol is a solvent that leaches chemicals
0.015g of lead in brass in a water supply system is much safer than in a high % alcohol solution.
alcohol strips while water doesnt.
any lead is bad lead.
stay lead free
those brass taps are made for water systems not stills and alcohol storage devices ;-)

Most brasses contain some lead.
Casting brass contains the least
Machining brass contains the highest
99% of domestic taps and metallic plumbing fittings are made of CAST brass. You have been drinking dreaded lead water for years :-)
Lead is only mutable (toxic) as an oxide or salt. Generally only the salts and oxides of lead are water soluble. Most lead salts and oxides are generally INSOLUBLE in ethanol.
The chance of a health risk presenting from lead leaching from a few brass fitting into your product, is insignificant. Most lead poisoning cases for distilled spirits comes from the use of car radiators (lead cores) as a product condenser, or the addition of lead acetate (sugar of lead) being used as a sweetener in the early 1900's.
Basic activated carbon filtering will remove 99% of all heavy metal salts from any spirit.
I firmly believe that using brass fittings with a lead free solder does not present a risk to a home distiller.
There is a much higher health risk with using PVC hoses and containers with high proof ethanol, and the plasticizers leaching out.
The two biggest health risks to home distillers (from a 1998 Swedish report) are burns from boiling liquid explosions, and substance abuse.

Our policy on this forum is brass is a bad idea and should be avoided

Brass does not need to have lead so not all brass has lead.

We are quite lucky with suppliers in Australia and its easy and convenient to source copper or stainless and avoid brass.
I would like to suggest also "pickling brass" before tinning it with lead free solder.
The pickling process draws the surface lead out of the brass. This should lower the amount of exposure.
