Pedrini Infinity Coffee Maker, Aluminium 3 tazze Passion

It's not about any seller just manufacturer or brand.That's the photos of Pedrini aluminum coffee maker (different model). After half a year, can see corrosion of bowel (aluminum reacts with chlorine from tap water as well is known to be corrosive when in touch with copper - it's ions are present in water especially delivered through copper pipes) and at contact between valve (brass = Cu a.o.) and Al bowel. Maybe poor quality alloy. Now coffee is acidic as well and that's what not good for Al. It goes into your system with your coffee.
