Note
Installers should inquire of local water purveyors as to the suitability of their supply for use in
hydronic heating systems.
If water quality is questionable, a local water treatment expert must be consulted for testing,
assessment and, if required, treatment.
Alternatively, water or hydronic fluid of known quality can be brought to the site.
