Does the drain funnel come with the screws?
Can waterproofing materials be used with all Oatey commercial drains?
No. Waterproofing materials can only be applied in series with our flanged drain assemblies. Please visit our website to select the right drain for your project.
How is a Roof Drain Receiver Pan secured during installation?
Oatey offers a #47700 Underdeck Clamp Kit that is recommended for every roof drain installation. This clamp is placed below the roof and attached to the drain body with 4 pieces of threaded rod, and 4 nuts. Once installed the clamp will secure the drain body in place so that the waterproofing seal is less likely to be compromised.
