LCP Roof Drain Sump Pan... Product Purpose and Description

You have to install LCP roof drain sump pan and it’s associated commercial roof drains to appreciate how easily they are assembled and and how quickly they are installed. It’s easy to assemble a roof drain to a pan and attach it to the roof. However, it is something entirely different to “sump” this entire roof drain assembly between joists that are 24″ on center without having to make a single major modification. This is a MAJOR time saver particularly for contractors and builders. Without this roof drainage system, you could easily spend hours building a wood box for the flat roof drains. It should not take more than 30 minutes to install, start to finish. 

Adding a center support is the only recommended modification. 

LCP roof drain installation kit is primarily designed for larger roofs such as commercial, industrial and institutional applications where the joist span is wide and the flat roof surface is large. This easy to install roof drain assembly makes the sumping process effortless! 

When Should You Use LCP Roof Drain Sump Pan?

  • LCP roof drain sump pan (standard version) is specifically designed to “sump”, or lower, the Zurn Z100 roof drain  (primary) and the Zurn Z100-89 overflow roof drain. Each roof drain has a 15″ drain bowl and bottom, or vertical outlets. The pipe connections can be no hub or threaded outlets. Very soon this unique sump pan will accept all major roof drain brands. 

  • See the INSTALLATION BASICS page above for more detailed information.

LCP Roof Drain Pan Improves Flat Roof Drain Performance

  • The physical flat roof drainage area of the sumped portion of the sump pan is enormous with perimeter dimensions being 45.75″ x 30.50″. ROOF DRAIN SUMP PAN DETAILWhen this feature is combined with the commercial roof drains massive 15″ bowl inlet, they create a powerful roof drainage system and can drain in excess of 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.)  

  • The combined components can dramatically improve the flat roof drains’ performance and drainage capacity and RAPIDLY removes rainwater from the flat roof thereby protecting your roof from the buildup of standing rainwater and extensive damage associated with it.  Similar sump pan receivers on the market DO NOT HAVE THIS FEATURE
