How to Rebuild a Yard Hydrant

Rebuilding or repairing a yard hydrant is a relatively easy task once you understand the process. Primary uses of a yard hydrant is to supply water for a lawn, livestock or unheated outbuildings. The hydrant attaches to a riser pipe and has a cast iron head with a bucket hook. The lever-type handle is at the rear of the spigot and you pull it upward to create water flow. A stop-and-drain valve is below the ground frost line to prevent pipe freezing. Repairs become necessary when the hydrant starts leaking.
