Req 6e — Replacing a Faucet
6e.
Replace a kitchen or lavatory faucet.
Faucet replacement is a great real-world plumbing project because it combines planning, tight-space tool use, shutoff control, and leak checking. It also reminds you that many plumbing jobs are more about patience than strength.

Before you start
Make sure the replacement faucet matches the sink layout. Count the holes in the sink or countertop, and check that the new faucet kit fits.
A simple replacement sequence
- Shut off the hot and cold supply valves.
- Open the old faucet to relieve pressure.
- Put a towel or pan under the work area.
- Disconnect the supply lines.
- Remove mounting nuts and lift out the old faucet.
- Clean the sink surface before installing the new faucet.
- Set the new faucet, tighten the mounting hardware, and reconnect the supplies.
- Turn the water back on slowly and check carefully for leaks.
Where Faucet Jobs Often Go Wrong
Slow down at these points
- Wrong faucet style for the sink opening pattern
- Supply valves that do not shut off fully
- Tight, awkward access under the sink
- Overtightening mounting hardware or supply connections
- Skipping the final leak check
After supply-side service work, the next task moves to the drainage side by taking apart and reinstalling a trap.
