Most rain barrels connect to a downspout using a diverter kit. Cut the downspout, attach the diverter, and connect the barrel. Ensure the barrel is on a level, sturdy base. Some barrels come with a hose for overflow.
A 1-inch rainfall on a 1,000 sq ft roof yields about 600 gallons. A typical 50-gallon barrel fills quickly. You can link multiple barrels for more storage.
Use a fine mesh screen over the opening to keep mosquitoes out. Some barrels have built-in screens. Also, ensure the barrel is sealed and the overflow is screened.
No, rain barrel water is not potable. It may contain contaminants from the roof. Use it only for gardening, washing cars, or other non-potable purposes.
Consider your garden size and rainfall. A 50-gallon barrel is standard for most homes. Larger barrels (65-100 gallons) suit bigger gardens, while smaller ones (20-40 gallons) work for patios.
Plastic barrels are lightweight and affordable. Recycled plastic is eco-friendly. Look for UV protection to prevent fading and cracking. Some barrels have wood-grain or stone textures for aesthetics.
Essential features include a brass spigot, overflow hose, and debris screen. Some barrels have a diverter kit, flat back for wall mounting, or modular design for linking. Consider ease of cleaning and child safety.
