Is the water pressure coming out of the garden hose attached to a full rain barrel enough to support a lawn sprinkler system? How much area will the water from a full rain barrel cover?
• The pressure depends on the water level in the barrel and will decrease as the water level drops (as the water is used). Most if not all sprinkler systems require fairly high pressure to operate and will not work with a rain barrel unless a separate pump is used, and using a pump will empty a rain barrel fairly quickly. Rain barrels work great with soaker hoses. The capacities of Fiskars barrels vary between models, but 50 gallons of water will cover a little over 80 square feet to a depth of one inch.
