Ask This Old House

Broken Fence; What Is It? Shower Valve; Keyless Chuck (3x3)

:

Roger repairs a broken fence with teenage neighbor Amanda Rao. Back inside, the guys ask, "What Is It?" Then, Richard restores hot-water flow to a shower for a house-sitter by repairing an anti-scald shower valve. Back in the loft, Tom shows how to upgrade an old drill by installing a "keyless" chuck.
