How Much Rainwater Can LCP Roof Drain Sump Pan Handle?

  • The flat roof drain alone, with it's massive 15" bowl inlet, and less the area of the LCP roof drain sump pan, can drain up to 110 gallons per minute of rainwater and serve a roof area of 5,300 square feet. This is based on a 4" pipe at 1/4" drop per foot at 2" per hour of rainfall. (ref 2018 Uniform plumbing code.)
  • This makes it suited to larger commercial and industrial flat roof drain installation projects.
