How To Make A Rain Barrel

Are you tired of seeing rainwater go to waste? You can easily make a rain barrel to collect it and use it later. A rain barrel is a container that collects rainwater from your roof through a downspout. You can use the collected water to water your plants, wash your car, or even flush your toilet. In this article, we will guide you through the steps on how to make a rain barrel.

What You Will Need

Before we get started, let’s go over the materials you will need to make a rain barrel. You will need a large plastic barrel, a spigot, a drill, a jigsaw, a downspout diverter, a screen, a hose clamp, and some silicone caulk.

Step 1: Prepare the Barrel

The first step is to prepare the barrel. Make sure the barrel is clean and free of any residue. Drill a hole near the bottom of the barrel for the spigot. Use the jigsaw to cut a hole in the top of the barrel for the downspout diverter.

Step 2: Install the Spigot

Next, install the spigot. Thread the spigot into the hole you drilled near the bottom of the barrel. Tighten it with a wrench. Use silicone caulk to seal around the spigot to prevent leaks.

Step 3: Install the Downspout Diverter

Now it’s time to install the downspout diverter. Place the diverter over the hole you cut in the top of the barrel. Use the silicone caulk to seal around the diverter. Attach the diverter to your downspout with a hose clamp.

Step 4: Install the Screen

To prevent debris and mosquitoes from entering the barrel, install a screen over the hole in the top of the barrel. Use a screen with a fine mesh to keep out small insects and particles.

Step 5: Test the Rain Barrel

Once everything is installed, test the rain barrel by allowing rainwater to flow into it. Check for any leaks and make sure the water flows through the spigot without any issues.
