How does a rain chain work and is it worth adding one to your garden? What you need to know if you want to install one

"Knowing how a rain chain works is key to getting the most from this practical yet decorative alternative to a downspout. They are attached to gutters and eaves, and work by channelling rainwater into barrels, landscaped flowerbeds or ornamental water features. They can also be attached to sheds, garages and other garden buildings. Although they work in exactly the same way as a downspout, rain chains are a much more attractive option."

"There are practical advantages to using rain chains as well as aesthetic ones. Compared to a downpipe, they help slow the flow of water, which can reduce the risk of flooding around your home. A rain chain directs water from your roof to the ground in a more controlled way, so it improves rainwater management in your garden too. How does a rain chain work? Rain chains work in the following way."

""A rain chain works by taking water from the roof and directing it safely to the ground in a controlled sequence," explains technical expert Jack Middleton. "The process begins when rain falls onto the roof and flows into the gutter. Instead of being channelled straight into a downpipe, the water enters the top of the rain chain, which is attached to the gutter or fascia.""

Rain chains attach to gutters and eaves to channel rainwater into barrels, landscaped flowerbeds, ornamental water features, or directly to the ground. They operate like downspouts but present a decorative alternative that integrates rainwater harvesting without large barrels. The linked cups or sections capture and pass water downward in a controlled sequence, slowing flow to reduce splashing, soil erosion, and drainage problems. Slower flow also lowers local flooding risk and improves garden rainwater management. Rain chains can be fitted to sheds, garages, and other garden buildings as practical, attractive alternatives to pipe downspouts.
