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

Superior grade roof drain pan SCP-modified and Frank Pattern single 8-1/2" diameter side outlet cast iron roof drains

SCP Modified Drain Pan is a totally unique, one-of-a-kind design that allows you to use side outlet or bottom outlet roof drains. See the sketches.

  • Use this sump pan when you have minimal space between the roof and ceiling and when your roof joists are 16″ on center.
  • Without this sump pan, it’s a total nightmare to try and build a wood sump box and fit all of the components in such a small space.

This is due to our patent pending plate adapter. This flat plate converts the standard sump pan to the modified version. This is simply bolted to the bottom of the sump pan.  Below is the image of the assembled unit

What are the benefits when from using SCP modified drain pan?

  • 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.
