3. Check the correct grounding of the system, in order to avoid galvanic currents
4. Check the correct sizing of the expansion vessel
5. Pay attention to excessive overpressure and water hammering phenomena in the system
6. Avoid to install the expansion vessel in unsuitable environments or areas subjected to particularly aggressive climatic conditions
7. Avoid the formation of condensation that leads to the development of corrosive phenomena (see question 13)
