After finishing work on a faucet in a customer's home, what should plumbers do?

• A. Show the parts and explain the repair to the customer
• B. Leave without explaining
• C. Charge the service call
• D. Take the old parts

Answer: (A)

After finishing work on a faucet, a plumber should show the parts used and explain the repair to the customer. This clear communication builds trust by letting the customer see exactly what was replaced or adjusted and understand how the fix works. It also provides an opportunity to demonstrate that the faucet operates correctly, share any maintenance tips, and discuss warranties on parts or labor. Explaining what was done helps prevent confusion or disputes about the service and its cost. While returning old parts or billing specifics may happen for other reasons, the essential step is to communicate what was done by showing the parts and describing the repair.
