Swapping a downspout for a rain chain is one of the few gutter jobs that takes less than an hour. Most of that time goes into planning where the water will land.
To install a rain chain, remove the downspout, drop a gutter adapter or V-hook into the outlet, hang the chain, trim it to length, and anchor the bottom in a basin or ground stake. Most chains come with a hook or adapter, and This Old House recommends testing the finished install by running a hose on the roof (This Old House). Plan the base first: the water needs a basin, gravel bed or dry well that carries it away from the foundation.
What you need
- A rain chain long enough to reach from the gutter outlet to just above the basin. Standard chains run about 8 to 8.5 feet for a single-story eave.
- A gutter adapter that fits your outlet. It spreads the chain’s weight across the gutter and channels water onto the chain better than a bare V-hook.
- A basin, rock bed or dry well for the bottom, plus a ground stake or anchor
- Screwdriver or drill to remove the downspout, pliers to open links, and tin snips or a hole saw if the gutter has no outlet
- Ladder, gloves and a helper

How to install a rain chain
- Pick the spot. Use an existing downspout outlet if you can. Choose a place where water can drain away from the house; the U.S. Department of Energy recommends discharge at least 5 feet from the foundation (source). Avoid spots right next to a basement wall or doorway.
- Remove the downspout. Unscrew the straps and the outlet connection and set the parts aside; you may want them back in winter.
- Clean the outlet. Clear debris from the gutter and the outlet. If there’s no outlet where you want the chain, cut one with a hole saw sized to your adapter and seal the edges.
- Fit the adapter or hook. Drop the adapter into the outlet or lay the V-hook or bar across the top so the hook hangs through the center of the hole.
- Hang the chain. Attach the top link or cup to the hook. Make sure it hangs straight down the middle of the outlet.
- Set the length. The bottom should sit just above or slightly into the basin. Open a link with pliers to remove extra cups or links.
- Anchor the bottom. Tie or clip the chain to the basin or to a stake driven into the ground so it can’t swing in wind.
- Test it. Run a hose on the roof above the gutter and watch for splash, overshoot at the top and pooling at the base. Adjust the basin or add stones as needed.
Installation tips
- Long drops: Bob Vila suggests aluminum over copper for chains longer than the typical length because it’s lighter (Bob Vila).
- Copper and aluminum: a copper chain touching an aluminum gutter can cause galvanic corrosion at the contact point. A matching-metal adapter or a plastic separator avoids it.
- Winter: ice adds weight to the chain and gutter. In freezing climates, many owners swap the chain back to a downspout for winter (Fixr).
- Heavy rain: cup styles carry more water than links. See rain chain problems and fixes.

What do you put at the bottom of a rain chain?
A basin, a bed of river rock, a rain barrel or a dry well. Whatever you choose should move water away from the foundation. See rain chain drainage ideas.
Can I install a rain chain without a gutter?
Yes, from a roof valley or eave bracket, but it only catches the water that runs onto it. See rain chains without gutters.
How long should a rain chain be?
Measure from the bottom of the gutter outlet to just above the basin or ground. Most single-story installs need about 8 to 8.5 feet.
Do I need a professional?
Not for a single-story install at an existing outlet. Hire a pro if the gutter is high, needs a new outlet cut, or is sagging.
