There are two versions of roof drain sump pan LSP:
Roof drain sump pan model LSP standard is specifically designed to "sump", or lower, the Zurn Z100 15" primary, bottom outlet cast iron roof drain.
Roof drain sump pan model LSP “modified” accepts the Z100-90 side outlet roof drain.
The integral sump feature lowers the roof drain 2-1/2" below the flat roof deck surface. Sumping a flat roof drain is vital if you want to maximize your roof drains potential and eliminate standing water on your flat roof.
The physical drainage surface of the sump pan is added to that of the large 15" roof drain and are a powerful combination. The combined surface area can dramatically improve the roof drains capability!
Similar sump pan receivers do not have this feature.
The outside sump pan dimension is 32" x 32" and the sump area is 22" x 22". The sump area adds to the large 15" bowl diameter to create a huge drainage area. ROOF DRAIN SUMP PAN DETAIL
The roof drain alone, with it's massive 15" bowl inlet, and 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 2018 Uniform plumbing code.)
