Gravity flow rainwater system


  • The roof drain and piping layout is restricted
  • The system can only be accompanied with the limited number of roof drains, with the total number being not more than four.
  • The numerous stand pipes with the larger pipe diameter would increase the quantity of the outdoor inspection shafts and increase the engineering quantity of the ground excavation.
  • With the adoption of the ordinary drainage pipes, the service life of the system would be shorter
  • Since the rainwater presents the air-water mixed flow state inside the pipe with the slow flow velocity, it is required to set up multiple inspection holes on the hanging pipes to prevent the pipes from blocking.
  • The hanging pipes would need the greater installation gradient, which would be not good for the long-distance hanging installation.
