Buying Guide
What downspout size does your home use?
Most common options are 2″x3″ standard and 3″x4″ oversize. Choose a diverter rated to fit your downspout size to ensure a tight seal and minimal leaks.
How much rainwater do you want to divert?
Consider a model with adjustable valve settings (OFF/Medium/High). This lets you control the volume into your barrel and prevents overflow during light rain.
Is debris a concern?
Models with built-in filter screens or easy-to-clean debris guards help keep your rainwater cleaner and reduce clogs in spigots or hoses.
What is your storage plan?
If you plan to connect multiple barrels or run hoses to distant gardens, pick a diverter with a longer hose and multi-outlet options to simplify installation.
Material and durability
ABS plastic or reinforced hoses resist UV and freezing conditions. Choose sturdy materials for outdoor use and consider a model with weather-resistant finishes for longevity.
Ease of installation and maintenance
Reversible spouts, included hoses, and straightforward filter designs help minimize installation time and maintenance. Look for designs that offer quick disassembly for cleaning.
Planned aesthetic and color
Some diverters come in color variants like brown or white. Match or coordinate with your gutter system to maintain curb appeal while staying functional.
