Roof Drains

We Have the Data


We Already Put It to the Test

You want to be IPC confident with your roof drain specification. Sure, you can calculate the flow rate, but that’s still a guess, not a guarantee. We test drainage products in our certified state-of-the-art facility, so you have the data and assurance to back your next project. Our test data on our Z100 roof drain will provide you with the flow rates you need to specify with certainty.


Comply Every Time You Specify

Comply Every Time You Specify

Roof drains are tested in our closed-lab facility. We follow a highly automated process and ASME Standard A112.6.9 to ensure controlled results and compliance. We understand that every application is going to be unique, so we have provided data on three different piping scenarios to allow you to make the best decision for your design.

  1. One-foot vertical drop by five-foot horizontal length with 1/4 bend elbow
  2. Two-foot vertical drop by five-foot horizontal length with 1/4 bend elbow
  3. Four-foot vertical drop

Know the Flow to Meet Code

Codes will keep emerging and adding extra steps to your already painstaking process. That’s why we decided to take them for you. Not only do our drains meet the most rigorous standards, but we can prove performance with real flow rate data gathered for Zurn drainage products. Here’s an example of our standard Z100 with a 15-inch diameter, low-silhouette poly-dome, and 4-inch no-hub outlet.
