Buying Guide
What should you look for in a plastic rain water tank?
Capacity and space: Choose capacity based on garden size, rainfall, and available space. 50–55 gallons fits many homes, while 53–55 gallons add flexibility with collapsible designs for storage when not in use.
- Material and durability: UV-resistant, UV-stabilized polyethylene or HDPE improves outdoor life and water quality.
- Overflow and connections: An overflow valve helps manage excess water; consider barrels that easily connect in series for larger storage.
- Portability vs. permanence: Collapsible or flat-back designs save space and suit renters; rigid barrels suit permanent outdoor setups.
- Safety and food-grade options: BPA-free plastics are preferable when storing drinking water, especially for long-term storage.
Where should you place a plastic rain barrel?
Position the tank under a downspout or near your garden irrigation line for easy water transfer. A stable, level surface prevents tipping, especially for taller or heavier barrels. If using multiple barrels, plan a common overflow routing to avoid water pooling near foundations.
How many barrels should you consider?
Two to three barrels provide more storage during rainy seasons and reduce the risk of overflow. Rubber hoses or dedicated connectors can join barrels to maximize capacity. For heat-sensitive climates, ensure shade or UV protection to maintain water quality.
Maintenance tips
- Regularly inspect for cracks or leaks, especially at joints and outlets.
- Clean gutters and screens to minimize debris entering the barrel.
- Winterize in freezing climates to prevent damage and prevent water stagnation.
Choosing the right option for you
For straightforward garden use, select a 50-gallon barrel with an overflow valve and simple attachments. If portability or storage between seasons matters, consider the collapsible 53-gallon option. For emergency preparedness and higher storage, a 55-gallon stackable tank offers durability and capacity. If you desire a more industrial or bulk storage approach, a BPA-free 55-gallon barrel with versatile fittings provides flexibility for transfers and different liquid types.
