R-6000 Yard Hydrant Leaking at the Packing Nut?

R-6000 Farm Yard Hydrant

A simple guide to help stop leaks around the packing nut.

Before you start

Shut off the water

Shut off the water supply before removing hardware. Mark the lower jam nut position for correct reassembly.

Don’t dig up your yard hydrant!

Most packing leaks can be fixed at the hydrant head. Digging is generally needed only if the standpipe or valve body is damaged.
