Step 4 · Measure and Purchase New Sillcock
Take the old sillcock to a hardware or plumbing supply store to purchase an exact replacement. The most critical measurement is the length. Match the length of the new sillcock to the old one (assumed 8 inches). Also, ensure the connection type is the same (a female sweat/solder connection in this case) and that it is compatible with your pipe size (typically 1/2-inch or 3/4-inch copper). While there, also purchase lead-free solder and water-soluble flux paste if you don't already have them.
