Brass in the ground - dezincification
If brass or gunmetal is to be used in the ground for a longer period of time (over many years), you should check the prevailing conditions in advance.
There are some wells of drinking water suppliers where the installation of brass is not possible. The drinking water lacks zinc and the water would draw this out of the installed parts.
This is known as dezincification of the brass, which then leads to pitting or pipe breakage.
The longevity of a brass coupling also depends on the acidity of the soil. Soil with a high humus content or clay is more aggressive towards brass than pure sandy soil. Brass couplings can be protected from harmful substances in the soil, e.g. by coating them with grease.
