Step 3 · Identify and Order the Replacement Faucet Part

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Carefully inspect the old cartridge or valve stem. Note the brand and model number (often found on a label on the faucet body itself). Take clear photos for reference. Use this information to find the exact replacement part online or at your local hardware store.
