Q: What is the difference between the SKUs 65041, 65051, 65061, and 65071?
A: The primary difference is the size they fit: 65041 fits 3″ ID existing drain pipe, 65051 fits 4″, 65061 fits 5″, and 65071 fits 6″.
Q: Do I need to remove the existing drain to install this unit?
A: No — this drain is designed as a retrofit “ReRoof” drainage unit that installs on top of the existing drain body, needing only access to the roof and a 7/16″ wrench.
Q: What material is the dome strainer and why choose the aluminum version?
A: The dome strainer is cast aluminum, which offers greater strength and durability compared to plastic versions. Choosing the aluminum dome provides better resistance to load, impact, and vandalism.
Q: What seal is used in this drain and how does it perform?
A: The drain uses a pre-compressed modified asphalt-impregnated expanding foam tape seal rated from –40 °F to +185 °F and designed for 150% minimum elongation, providing a flexible and watertight seal against the inside of the existing drain pipe.
