Buying Guide: 70-Gallon Rain Barrel Shopping Essentials
- Capacity planning: If you specifically want around 70 gallons, consider stacking two 50-gallon barrels or choosing higher-capacity models when available. Think about future expansion and how much water you typically use for irrigation.
- Placement and space: Flat-back models are ideal for mounting against a wall. Elevation helps with pressure; however, ensure stable ground and proper anchoring of stands.
- Materials and durability: Look for UV-resistant, BPA-free plastics and corrosion-resistant spigots. Recycled materials are environmentally friendly and often lower cost.
- Filtration and debris control: Screens keep leaves and dirt out; check for easy-clean lids and accessible inspeaction points to maintain water quality for plants.
- Connectivity: If you plan to expand, choose barrels with side spigots or link kits designed for series connections to increase total storage without taking more space.
- Maintenance ease: Removable lids and accessible overflow mechanisms help prevent blockages and overflow during heavy rain.
- Water management: Consider overflow placement and compatibility with downspouts to redirect excess water away from foundations and landscaping.
Frequently Asked Questions
- Can I really store 70 gallons in a single setup?
– Most common residential rain barrels range from 50 to 60 gallons. To approach 70 gallons, plan for two barrels or a larger-capacity model and consider the addition of a stand to optimize drainage. - What is the best way to connect multiple barrels?
– Use barrels with compatible spigots and a link kit or side connectors designed for series connections. This creates a shared reservoir that drains efficiently into subsequent barrels. - Are flat-back barrels necessary?
– Flat-back designs maximize wall placement and minimize space usage, making them ideal for constrained yards and tight spaces. - Is a screen necessary?
– A screen helps prevent debris from clogging the spigot and flush-out valves, keeping water cleaner for your plants. - Should I choose a barrel with an elevated stand?
– Elevation improves water pressure for easier filling with watering cans. Ensure the stand is sturdy and level to avoid tipping. - Do I need a separate planter on top?
– Integrated planters provide decorative value and can utilize the water in a mixed-use design, but they may complicate cleaning and maintenance.
