Why is Roof Drain Pan SCP referred to as "Modified"

  • Roof drain pan model SCP modifieds’ totally unique and one-of-a-kind design of allows you to use side outlet roof drains rather than the one piece combination bottom outlet roof drain that is used on the standard sump pan. See the tab above for more info. 

This is due to our patent pending plate adapter. This flat plate converts the standard sump pan to the modified version 

Superior grade roof drain pan SCP-modified adapter is designed to convert the sump pan from bottom to side outlet roof drains.

What are the benefits when from using SCP modified?

  • SAVE MONEY… you don’t need to buy a separate sump pan if you choose to use side outlet roof drains. If you need to mix bottom and side outlet roof drains on the same project, no problem, use the same pan. 
  • Sumping a roof drain is vital if you want to maximize your roof drains potential and eliminate standing water on your flat roof. 
  • INCREASED SURFACE AREA DRAINAGE: The physical drainage area of the “sump” adds to the bowl areas of both of the roof drains and combine to improve flat roof drainage. This is not the case with other sump pans on the market.
  • PLUMBING CODE COMPLIANCE: The overflow roof drain sits two inches higher than the primary per plumbing code requirements. The overflow must be plumbed separately from the primary roof drain as it acts as a fail safe mechanism should the primary drain become plugged. There should never be more than 2″ of standing rainwater on a flat roof.
  • IMPROVED RAINWATER CONVEYANCE: Each roof drain, less the area of the 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 2015 Uniform plumbing code.)  When you add the enormous sump area, the drainage efficiency is greatly increased.
