Which water does not cause rust

The Grünbeck purity law: no lime, no rust, no dirt.

rust

Sometimes water is brownish red in color. Rust is often to blame for this. It may have got into the water naturally, which dissolved iron from rock. Still, there are many reasons to insist on stainless water. Rust not only affects the taste of the water. It can build up, causing further rust formation and eating holes in old metal pipes. That is why our Grünbeck water experts have developed solutions that filter out rust using suitable water filters and thoroughly rinse the pipes so that rust deposits no longer stand a chance. But our products are not only preventive. To a certain extent, they can also repair rust damage that has already occurred.

dirt

Viruses and bacteria love dirt in the water, which is a potential shelter and breeding space for them. Filtering dirt out of the water is therefore also an indirect and important contribution to disinfection. Filtration makes the water what it should be: good for people and their health. Dirt gets into the water more often than you think: for example, due to construction work or damage to the drinking water supply. That is why DIN 1988 specifies filters for domestic water installations with metal and copper pipes and also recommends them for plastic pipes. And that's why we have developed efficient filter systems that banish all dirt from the water.

lime

Too much calcium and magnesium in the water makes water hard. We're making it soft again, and for good reasons. When water is heated, the substances calcium and magnesium dissolved in the drinking water react with hydrogen carbonate to form lime (calcium carbonate). And the resulting lime is deposited on the pipes. It can make water heating more expensive and seriously damage the pipe system for the water supply. That is why we soften the water. In addition, suitable Grünbeck technologies filter out lime or add precisely dosed active ingredients for water treatment to drinking water. In this way, water remains largely free of lime.
