How To Install LCP Roof Drain Sump Pan

If this assembly takes more than 30 minutes to install, then it’s too long. The superior design effectively eliminates the need to build a wood “sump box” which is laborious and ultimately expensive. This is a major time saver 

Having the prefabricated roof drain assembly ready to install takes the effort out of the work.

This short video will show you before and after shots or the project.

LCP Roof Drain Sump Pan is built around the concept of POSITIVE ROOF DRAINAGE. Unless your roof drains are the lowest point on the flat roof, you will have pools of standing rainwater or “negative” drainage. Positive roof drainage means (in this case) that the roof drain are lower than the flat roof.  Gravity then pushed the rainwater toward and into the roof drain. While this seems like a “given”, it doesn’t explain why so many roof drains are higher than the flat roof.

A sump pan is a FAST and EASY system to get positive drainage. It can prevent further ponding in addition to having many other benefits.

This feature automatically lowers your flat roof drain which eliminates the need to build a separate wood sump box. The wood box is a labor intensive process. When you add up the labor and materials required to build the wood box, the metal sump pan becomes a very cost effective solution.
