Replacing a broken rain barrel spigot is a very easy repair. Mine broke a while back. It was plastic and with exposure to the sun, rain, heat, and cold was bound to break eventually. I used a metal spigot that easily replaced the plastic one. This simple rain barrel spigot repair shouldn't take you more then 10 minutes from start to finish!

I replaced it with a metal spigot like this one: https://amzn.to/3ykxbmu (Amazon Aff. Link).
