I’ve never liked the faucet in my upstairs bathroom, and when I bought my house, it didn’t have a stopper. I was always afraid of dropping stuff down there! Plus, I’ve had issues with water leaking, so I thought this would be the perfect time to solve that mystery too.
Here’s what you need:
- A faucet kit (including drain assembly)
- A wrench
- Vice Grips/locking pliers
- Plumbers Putty
- A small bucket or paint tray to catch the water
- Old towel
What to do:
This is a GREAT VIDEO to watch before you start.
1. Turn the water valves off. (Turn the knobs as far to the right as you can)
2. Disconnect the water lines from the old faucet. Disconnect the mounting nuts that hold the old faucet to the underside of the sink.
3. Remove old faucet from the sink. Clean around the area and use a screwdriver (if necessary) to scrape carefully any residue/old caulk off.
4. Put new faucet into the holes in counter. Reattach the mounting nuts to hold it tightly to the counter.
5. Reattach the water lines to the faucet hookups.
**If you’re also replacing the Pop-up drain assembly, continue with the directions. Otherwise, turn the water back on and check for leaks.
6. Unscrew the tailpiece that connects the P-trap with the pipe coming from the drain. See a great explanation of all of these directions HERE.
7. Unscrew the connector between the pip connecting the drain and the drain. Pull the gasket (rubber) down. Then you should be able to put the piece upward to loosen the drain connection to the basin in sink. Be prepared for all kinds of hair and gunk in there. GROSS.
8. Remove all old pieces.
9. Get out the plumbers putty and roll a snake. Wrap it around the underside of the drain piece and set into the sink. This creates somewhat of a seal, and it doesn’t matter if some seeps up while you’re pushing it down.
10. Then connect the new pipe, gasket, and washer underneath the sink. Connect back up with the P-trap.

11. Drop the stopper into the drain (facing the correct direction) so you can insert the pivot rod (rod with the ball on it) into the stopper.
12. Connect the pivot rod and the lift rod with the Clevis strap (yeah, if I didn’t have the diagram above, I would have no idea the proper names for these things…)
Then turn on your water for at least 15 seconds and look for any leaks.

Thank you so much for these directions. My first time replacing a faucet. Am putting in new faucet in pedestal sink and did not want to remove it. Your directions, along with the Delta video, were the only ones that helped me do it myself.
