I have a Moen bathroom sink faucet Model Number 4570. It has been in place for about 25 years. I am the original owner. The cold water faucet finally failed and I ordered new parts from Moen (the cartridge plus various adapters and also their tool to aid in removing a cartridge nut. After removing the faucet handle and the cartridge nut, I then tried to extract the cartridge using needle nosed pliers as per the Moen instructions. After being in place for 25 years, it did not want to budge (not surprising).
I then looked on the internet to see if anyone else had experienced this problem and it looks like it has been a common problem. I read all the suggestions and tried putting vinegar on it to no avail. I was impressed with one proposal from an engineer in which he suggested attacking it from the underside by disconnecting the tubing and inserting a 5/8” rod and tapping it with a hammer.
I am 82 years old (also a retired engineer) and I did not feel like getting under the sink. I then tried to attack it from the top. I fashioned a loop out of some old pipe strap I had and I was able to attach the loop to the top of the cartridge with the screw that is used to attach the top extension to the cartridge. I then fashioned a lever arrangement using a block of wood and the lever that goes on my floor jack. See the attached photos. With this arrangement, the cartridge just popped out with very little effort.
Here is a photo of the Pipe Strap loop that I attached to the top of the cartridge. This photo shows the cartridge after extraction.
This photo shows the arrangement of the lever with the cartridge still in the housing.
I added some extra silicone to the two “O” rings on the new cartridge and then inserted the cartridge and finished the job. The valve turns extremely easily – maybe I did not need the extra silicone. Moen was very helpful in sending the parts (at no charge since I was the original owner).

A shower that hasn’t been used in about a year is no longer producing cold water (and the pressure seems lacking when the faucet is set to cold). Other showers in the house have no issues.
It’s a single handle faucet by Moen. I was able to remove the handle, but the escutcheon seems to be sealed to wall? My assumption is this piece is necessary to replace the cartridge (which I’m hoping is the culprit).
Any sense of what cartridge this might be? Do I absolutely need to remove the escutcheon?
Thank you for any assistance and guidance!

There is a cartridge removal tool you can use, I have never failed to get a cartridge out when resorting to it:
You can often borrow or rent this tool from a reputable plumbing shop (note importance of "plumbing shop", don't even waste your time at the big-box stores). There are other tools you will see, but they do not work as well as the one pictured.
Tap seems to be dripping so wanted to know if anyone might know the cartridge number for this moen faucet. I think it could be from 2005 ish but not certain and would like to order a replacement before trying to take it apart.
Am replacing the faucet cartridge of my bathroom sink faucet.
Removed the handle. Next while trying to remove rest of the assembly, I think I twisted the center screw little hard and it broke the thread. The white piece that holds the screw.
Now the screw just rotates, not threading out. Any alternatives I can try here to remove the screw.
