Here are some LCP Roof Drain Pan installation applications

Model LCP roof drain pan is best suited to large commercial, industrial and institutional applications where there are large roof surface areas to be serviced

How to use the LCP roof drain sump pan

The following information shows three types of installation methods commonly used with LCP sump pan. These apply to wood framed roofs mainly, however the pan and drains can be used on steel and concrete decks with perfect adaptability. Select the method that suits your project requirements. You can use 12" or 15" diameter roof drains with this pan.

1) Parallel Installation

As shown, the LCP sump pan is installed parallel to the joists. This method does not require any modifications to any of the components that comprise the kit or to the building structure.  

It is designed to fit between joists that are 24″ on center minimum, but can be used where the joist span is wider. such as metal or concrete roofs. 

It is recommended that a center brace is installed for lengthwise support on a wood roof   End blocks can be added additional strength and to prevent deflection of the roof. The photo below illustrates this concept.  On metal or concrete roofs, added support is generally not required.  

2) Perpendicular Installation

In the photo below,  LCP sump pan is installed with 15.” ( flange diameter) primary and overflow Zurn roof drains with 4″ pipe sizes, and is installed perpendicular, or 90 degrees, to the roof joists. 

As such, the framing will need to be modified to accommodate installation of the components.  This is generally not the case with a parallel installation.   

The photo below was a new construction project and the framing was factored into the design.

Please note that this sump pan has been modified since this picture was taken and has less space between the roof drains. Refer to the spec sheet. All of these kits can be purchased on the shopping cart.

3) Multi-level roof drain installation description

In some cases, the building designer would prefer to have the overflow roof drain at deck level. The multi-level configuration was designed for this purpose.

It uses two separate roof drains and sump pans. The primary roof drain is installed in a model LSP sump pan which lowers it two inches below the roof surface.

The overflow roof drain is installed at the roof level with a FLAT DRAIN PLATE.  This puts the water dam two inches above the roof.

The double sump pan, model LCP,  is not used in this case.

In this particular installation, the pan was lowered into the plywood. While this is an excellent idea, generally the sump pan sits on top of the plywood. Nevertheless, it accomplished the goal.

  • This setup shows the standard deck plate or sump receiver that is regularly supplied with roof drains. Since it does not have the sump feature engineered into it’s design, the installer would need to build a wood “sump box” and modify the pan to adequately “sump” the drain. This applies to a wood framed building. 
  • The standard deck plate works well with insulated roofs where the roof covering is thicker as the the tapered insulation creates the sump.
