Roof drain sump pan SCP was designed

to be a installed by nearly anyone. It can be installed on wood framed, metal and concrete roofs.

Contractors can get an entire roof drain installation project completed in a fraction of the time that it would take previously using the old and antiquated system of building wood sump boxes.  

Fabricating a sump pan on the job is a waste of time when you can use a prefabricated sump pan.

Using our prefabricated roof drain pans SCP is the key to increased production. 

How Much Rainwater Can This Flat Roof Drainage System Drain?

​Here's an example that is straight out of the Uniform plumbing code pages...​Each flat 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 size at 1/4″ drop per foot at 2 inches per hour of rainfall. (ref 2018 Uniform plumbing code.)  This doesn't even address the area of a the sump in the drain pan. When you add the sump area, the drainage efficiency is increased. 

​The physical drainage surface of the sump pan and the bowl diameters of the primary roof drains provide plenty of surface area and achieve excellent flat roof drainage.

  3. It is installed between joists that are 16" on center without any modifications.

  4. ​It has reinforced riveted joints providing an extra layer of strength.

  5.  The overall dimension of the sump pan is 34-1/2" x 26" x 2" deep.  SCP sump pan specs  

  6. The sump area of the sump pan is approx 13-1/2" x 22" and adds to the surface area of the flat roof drain bowl, thereby increasing drainage capacity.  

  7. The roof drain pan accepts either a bottom outlet combination flat roof drain or bottom and side outlet single roof drains without modification via the adapter.

The answer to that question is easy. There is no comparison to the SCP roof drain sump pan. The major roof drain manufacturers simply do not make a real sump pan. They make a sump receiver and call it a sump pan but it does not, nor is it intended to, lower or "sump" a flat roof drain. Not only is SCP roof drain pan a true sump pan, it is more cost effective. But there are more benefits to this totally unique roof drain sump pan.... 

When Should You Use This Roof Drain Pan SCP? 

Product Purpose

  • The main purpose of the roof drain pan model SCP is to make the roof drains the lowest point on the roof. In doing so, it eliminates standing rainwater on a your flat roof when properly placed at the lowest points on the flat roof. 

  • Further, this sump pan provides a standardized FAST and EASY method to "sump" or lower the Frank Pattern combination roof drain.  No need to build cumbersome and labor intensive wood sump boxes.  

  • Finally, this "sumped" flat roof drain will dramatically improve the roof drains performance.​ 

Firstly, with our newest patent pending development, the SCP single roof drain adapter, you can now install bottom or side outlet single flat roof drains IN THE SAME PAN. NO MODIFICATIONS REQUIRED!  So if you have minimum space between the roof and the ceiling, SEE HERE, this sump pan will accommodate the side outlet flat roof drain. 

​Secondly, you can add a 2" water dam to one of the single flat roof drains to make it an overflow. So no matter which sump version you use, you have your combination flat roof drain set up ready to go!
