Primary/secondary piping is a way to achieve hydraulic separation by connecting multiple hydronic circuits with their own circulators to prevent interference. Using a pair of closely spaced tees is a common method to achieve this.
Plumbing systems in buildings require careful selection of vertical or horizontal piping distribution. The building type is a key factor in this decision, and relevant codes and standards must be followed.
Sooke School District responded to the influx of young families by swiftly constructing schools for 1,200 students. These LEED v4 Gold-certified buildings seamlessly integrated into the landscape, featuring photovoltaic panels, geothermal HVAC, and district heating for efficiency. Underground piping ensured optimal comfort while minimizing waste.
PPI MS-7 includes detailed specifications for four plastic piping materials which have been proven in ground-source heat exchange systems: HDPE, PE-RT, PEX, and PP (PP-R and PP-RCT).
CPVC has been used for residential plumbing in the U.S. for more than 60 years and is unique among today’s plumbing materials.
