What is a Sillcock?
A sillcock, commonly known as an outdoor faucet or hose bib, is a vital component in many homes. It provides an external water source, essential for gardening, washing vehicles, and other outdoor tasks.

Fortunately, disassembling and repairing a sillcock is a straightforward task you can accomplish with basic tools and some know-how. This guide will walk you through the process of fixing your sillcock and saving money on professional repairs.
