Reassemble and Restore Water Supply

What happens here

Carefully reinsert the stem assembly, with the new washer, back into the hose bib body. Hand-tighten the back nut first. Then, use the two large adjustable jaw wrenches to fully tighten the back nut. Ensure one wrench holds the main body firmly while the other tightens the back nut to prevent twisting. Once tightened, return to the main water meter and use the meter key to turn the water supply back on. Finally, open the hose bib handle completely and check for any leaks around the handle or the outlet, confirming the repair is successful.

Goal: Restore the hose bib to full working condition and confirm the repair.
