💬 What real owners actually say
Synthesized from 2026 owner reviews & discussions across social media — the things spec sheets leave out.
Capacity and expandability. Link barrels to store more for dry spells.
Diverter and overflow. Good diverters fill cleanly; overflow protects your foundation.
Keep it screened. Mesh blocks debris and stops mosquitoes breeding.
UV-stable material. Sun-resistant plastic lasts outdoors for years.
Check local rules. Rainwater harvesting is regulated in some areas — verify first.
Each slider sets how much each criterion matters to you (0 = ignore, 10 = critical).
