Buying Guide
- Size and pipe compatibility: Match the drain diameter (3″ or 4″) with your existing DWV pipe size for a seamless fit and optimal flow.
- Materials and durability: Cast iron domes paired with PVC bodies offer strong corrosion resistance for exposed roof environments.
- Debris protection: Dome-style or grate designs help restrict leaves and sediment from entering the drainage system, reducing clogs.
- Flow area and capacity: Larger open areas improve drainage during heavy rainfall; consider multiple outlets for long roof runs.
- Ease of installation: Look for universal adapters and secure fastening options (brass inserts, stainless bolts) to simplify mounting.
- Freeze protection: In colder climates, units with anti-freeze features or frost resistance prevent discharge line blockages.
- Maintenance and accessibility: Choose designs that allow straightforward cleaning and debris removal without heavy disassembly.
- Aesthetics and compatibility: Consider what fits with existing roof finishes and architectural style while meeting functional needs.
- Clip-on vs. bolted assembly: Bolted assemblies tend to offer stronger, more secure connections in harsh weather.
- UV resistance: For exposed applications, UV-stable polymers extend service life and reduce material brittleness.
