If a Cold Water Storage Cistern (CWSC) is located in the roof space of a dwelling with thermal insulation beneath it, a plumber should ensure that the cistern is properly insulated to prevent freezing in colder weather. Additionally, they should verify that the insulation does not obstruct access to the cistern for maintenance purposes. It’s also important to check that any pipes connected to the cistern are insulated to avoid heat loss and potential freezing issues. Finally, the plumber should ensure that the installation complies with local building regulations and standards.
