Zurn ZC100 Roof Drain
Use the Zurn ZC100 roof drain model for large roof surfaces such as commercial, industrial and institutional applications
The large Zurn ZC100 roof drain bowl, 15″ in diameter, is designed to draw large quantities of rainwater into it and rapidly convey it from the roof surface. When combined with the correct pipe and fitting size that serves the square footage, it becomes highly effective in accomplishing this task.

See how to install the J.R. Smith 1010 roof drain. While the video shows a Zurn roof drain, the Smith roof drain is installed in the same manner.
Roof Drain Pan Options
Here are the roof drain pan options for this roof drain
1) The Sump Receiver
The sump receiver is a flat plate that “receives” and supports the Zurn roof drain – Z100. There is no lowered section ( sump) and so puts the drain at or above deck height. Make sure that your roof covering is thick enough to leave the roof drain lower than the roof otherwise you will have pools of standing rainwater. The receiver requires an underdeck clamp to anchor it to the roof structure.
2) Top-Set® deck plate
This deck plate also receives and supports the roof drain. It is recessed but still leaves the roof drain at deck height. You should have a thick enough roof so that the roof drain sits lower than the roof once the membrane clamp has been installed. The roof drain must be lower than the roof to avoid standing rainwater.
An excellent feature is that the roof drain is bolted to the pan and the pan is screwed directly into the roof joists thereby eliminating the need for an underdeck clamp
3) Roof Drain Sump Pan
The sump pan lowers the roof drain 2-1/5″ below the roof level so that the thickness of the roof covering isn’t a factor. It will make your roof drain lower than the roof and is designed to prevent standing rainwater.
The roof drain sump pan requires no underdeck clamp and is likewise secured as the deck plate. The video below shows this procedure. This product is an aftermarket accessory and is not manufactured by Zurn Industries.
