This requires professional calculation!
*Domestic water: Calculate and regulate the water volume based on the number of people, water quota, and water supply method (municipal direct supply or variable frequency pressure).
*Fire water tank: The initial fire water consumption must be calculated strictly in accordance with national fire safety regulations (such as GB 50974), which is a mandatory requirement! The capacity is not enough to pass the acceptance. Be sure to consult professional fire designers or water tank manufacturers like us.
