Steps for Replacing Pedestal Sink Parts:
1. Start by shutting off the hot and cold water valves to the sink. Open the faucet to ensure the shutoffs hold.
2. Disconnect the hot and cold water supply lines using pliers. There will still be a little bit of water in these hoses so be prepared with a small bucket or a rag to catch the water.
3. Remove the basin of the sink from the base of the pedestal.
a. The basin is usually held against the wall by two bolts, which can be loosened using a wrench.
b. Richard recommends scoring along the wall with a utility knife to prevent any caulking between the sink and the wall from damaging the wall.
c. To loosen the drain connection, carefully slide the pedestal away from the basin until you can get a wrench around the drain.
d. Once everything is disconnected, pull the basin away. Richard suggests sliding a putty knife in between the score marks from the utility knife with a hammer to ensure that all the caulking has been separated from the sink.
4. With the sink removed from the wall, replace any parts that require replacing.
a. To replace the supply hoses: disconnect the nuts from the base of the sink using a basin wrench. Secure the new hoses using the same process in reverse.
b. To replace the pop-up assembly: loosen the drain connection using the basin wrench. Disassemble the linkages for the pop-up and pull the plunger from the top of the sink. Reverse this process for the installation. In the case of the video, Richard replaced the pop-up with a push-button drain that required no linkages and came with the faucet.
c. To replace the faucet: disconnect the nuts underneath the hot and cold handles using the basin wrench. Pull the faucet and the handles out of the sink. Slide the new faucet into the hole. Apply plumber’s putty underneath the faucet on the face of the basin. Tighten the new nut from the underside of the basin. Make all the new hose connections to the faucet. Newer models have plastic push connections that can be made without any tools.
5. Place the sink back on the bolts against the wall and on top of the drain.
6. Tighten the bolts and the nut for the drain using a wrench.
7. Slide the pedestal fully into position.
8. Connect the hot and cold water lines to the hot and cold shutoffs using the wrench.
9. Turn the water back on.
Resources:
Richard installed a Pfister Pasadena faucet [https://amzn.to/2Vdp4r9] in a brushed nickel finish (https://www.pfisterfaucets.com/). The faucet also came with a stopper, drain pipe, and an installation tool to do all the work.
The other tools and materials Richard used to remove the old faucet and install the new one, including the wrenches and the plumber’s putty, can be found at home centers and plumbing supply houses.

Plumber dude is a kung fu practitioner.
No way am I having a stopper that I have to reach down in the water to release!
Hey
Is it OK for the braided supply lines to bend in a circle like that? @8:32
What would cause my sink faucet to have very low pressure ?
So cool
We have 4 pedestal type sinks and I ABSOLUTELY HATE IT!
Another good vid by Richard. Has such a likable disposition
Good stopper design, eliminates the linkage and the adjustment. I like the clean look of the faucets.
As you said, Richard, the sink didn't have to come off the wall. The caulk didn't need to be cut to lift the sink off the base either, it would have flexed enough after bolts in wall were loosened.
I like that pop-up/pop-down sink drain. No more fussy assemblies. Best part of that whole video. Are these drain assemblies available in the big box stores? Or only in the professional plumbing supply houses? Richard, thank you. You’re a pro and are appreciated!
Now I see why the plumbers never called him back
Question for Richard. How does he deal with full city water pressure and how dangerous is it ?
I’d just move…LOL
At least take some of the old wallpaper off with that putty knife. Lol
So when your sink is filled with dirty water you have to reach your hand in that water and press down on the stopper?
Leave it to Rich to find the gross brown stuff and touch it with his finger lol
He is not kidding about plumbers not liking a pedestal sink
These are the worst jobs to do but can be done with a good amount of time invested
Thitooey's favorite saying, "GOOD"…
I would rather run 100 ft of 4 inch cast iron than hang a pedestal sink.
He didn't replace any pedestal sink parts… he replaced faucet and drain parts. He even says the a pedestal sink has 2 pieces but then didn't replace either one…
With enough finesse and patience you can replace all these parts without detaching the sink from the wall or removing the pedestal. It takes 3 times as long and requires 10 times the patience to get your wrenches under the drain, but it’s doable. That way you don’t need to remove, recaulk, or repaint. Easier and quicker for professionals to remove when time is money.
Some smooth editing in post at 5:29 to keep from youtube de-monetizing lol
Richard where are u based?
He'd be better off using some metal rod instead rather than using his hand to push down every time that stopper in the dirty water.
A plumbers nightmare
Richard "Full City Water Pressure" Trethewey
I've had problems with those pop up stoppers before ,maybe they're better engineered these days.Richard is the best and makes plumbing fun !
Hate those sinks. Zero access to the trap.
Nice video, but I hate how most of the plumbing components are plastic now.
The sound of the plug unit is terrible
Like the guitar music!
Wow, Silk Studios bras are a YouTube ad for This Old House. Weird.
I'd like to share this:
It is common knowledge we have P Trap on our sink and shower floor drain – to prevent sewer gas from backing up. But did you know that the P-Trap itself, after some time would collect gunk from all the soap, dirt and grim along it's inner surface and it stinks? There are numerous remedies to this such as Vinegar + Baking Soda etc… But nothing beats using a high pressure washer.
called a plumber to install a faucet, what a beta
Missed a step.
Run the faucet with the aerator removed to clear the lines.
"Homeowner gets the honors" – bad practice, good TV?
Pedestal sinks look great in the trash.
You’re not going to change the trap? Come on, Richard.
good job! I don't like the stopper style though. I'm imagining a mess that I'd rather not have to stick my hands in. hmmm
Am I the only one who thinks the quick connect water hoses were sexy? He makes plumbing look fun – even pedestal sinks!
I figured it out bit: 37kUB16c1dW1wUFX6LdSGbVHfwN8kPCMBj
How useless is this homeowner?
Changethetrap
And expect to replace it within two yrs cause it’s all junk made in China from slave labor camps.
Fun fact: Soon to be coming here to the US, thanks to all of you sanctimonious, brainless mask wearers for a fake pandemic.
That was a good one. A tip from me: always keep the plug hole blocked / covered when working in a sink or bath to prevent items falling down there.
I wish Richard was my best bud and he would come over to my house and do weekend projects. I would make coffee.
too many shortcuts.
This took way longer than 10 minutes tho lol But so glad for your tutorial on this!
This just convinced me not to put a pedestal sink in the WC in my next house.
This was very helpful and wouldn’t you know it, the faucet you replaced is exactly the same model I replaced. Must have been popular 15 years ago.
They make a plumbers claw U can get at hardware store. Plastic, will pull a Ring right out along with slyme!
Anyone know the name of the guitar tune?
nice video, I'm looking to replace our kitchen faucet for an old porcelain sink. Our tools are too large because the space where the facet bolts sits under the porcelain is so small. barely an inch. I'd hate to take out the whole sink(not in our budget) any tips on tools would be really helpful. 😀
Should always take out the aerator before turning the water on to prevent any debris that has been introduced into the lines. This happens when you shut the feed valves off and back on, (especially on multiple turn valves)
Great video. Wish I could get Richard to come to my house. My plumber refused to work on mine, and I'm too old and weak to do it myself.
destroyed wallpaper is seen behind the new one though?
Well, shoot. I had hoped changing out the faucet on a pedestal sink would be easy. I think I'd better call the plumber instead of trying it myself…… Great video with a lot of good and useful information and I really like that fancy stopper.
