• Every other drain will rust. Topwet's won’t.  — They use high-performance polyamide instead of metal. It’s UV-stable, corrosion-proof, and built to last, meaning fewer callbacks, replacements, and warranty headaches.
• The self-heated drains melt snow and ice automatically.  —  Topwet's built-in heating cable activates as temperatures drop. It prevents freeze-ups and roof damage, giving building owners peace of mind and reducing emergency service calls.
• The factory-bonded waterproofing membrane seals in minutes. —  Each drain comes with a pre-attached membrane (TPO, Bitumen, or custom options). No tools, no mess, no leaks. It installs fast and eliminates sealing errors on-site.
