Step 5 · Reinstall the Faucet Stem
With all the new seals installed on the stem, it's time for reinstallation. Carefully guide the washer-end of the long stem back into the faucet body. Push it in gently and steadily until it is fully seated. You may need to gently rotate the stem to help it align properly with the inside of the faucet body. Push it all the way in until the threaded portion where the packing nut goes is exposed and in its correct position.
