Replacing Moen 1224 catridge in my Moen bathroom faucet 

Thanks for nice comment. Funny you mentioned having difficulty removing the faucet handle. I had the same problem at another sink. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1izCXI6Mctw.html

It's a 1x2, but yeah. I like that.

Recently, I could not remove the plastic retainer ring with corrosion and calcium buildup. The plastic retainer ring got shredded in the process of trying to loosen the ring. Because Moen has record that I am the original owner of the faucet, the sent me a new valve body which includes new cartridge and retainer ring. Yours maybe different. www.amazon.com/Moen-100743-Replacement-Part/dp/B000CNGZWC/ref=sr_1_1?crid=3JGZHWBQHBBMJ&keywords=moen+100743&qid=1704948932&s=hi&sprefix=moen+100743%2Ctools%2C142&sr=1-1

Yes, I had one that was stuck in rather firmly. Pliers and channel locks no good. I tried to wedge a screw driver and putty knife. I pounded it with a chisel. I bought the removal tool from hardware store. I finally wanted to try one more thing first. I sprayed it with a 50/50 water/vinegar solution. Let it soak 20-30 minutes. Put the screw back in and used the claw on hammer supported by two 2 x 4's to get some leverage on it. It finally came out!!!

Moen is awesome I just called for replacement cartridges for tub shower no charge

They really are a great company

Good job. I too noticed some calcium at the lower O-ring on my project. There is always a little bit of learning with DIY. Next time you will be faster and more confident. My attitude is I will try it myself then call a plumber if needed.

I had read somewhere that the Moen 1224 replacement cartridges are water saving (1.5 gallons of water per minute). Its a possibility your old cartridge was not water saving cartridge.

@@masterofnone7243 Makes sense. Thanks!

This is the tool I used.

My only guess is that the new cartridge is not fully seated. If you look at your old or new cartridge, you will notice a square tab on both side of cartridge that needs to fall into a match cutout. It took me 3-4 tries before mine into place. It doesn't just fall in.

Hello. I am not a plumber so I don't have a specific answer. Only thing I can say is make sure the cartridge is fully seated and the black O-rings are not damaged.

@@masterofnone7243 Thanks for the answer The reason why it was leaking was because I tried to fix the side where the cold water was, I tried the other side and it was fixed So if it still leaking try the other side but your video was awesome thank you.

Disclaimer I am not a plumber. I am in the medical field. Maybe try turning off the water on one side to isolate what cartridge is giving you the problem. Its a possibility that one cartridge is not installed properly. Also I am assuming that your old cartridge matched the new cartridge you installed.

thank you

You are absolutely correct.

@@masterofnone7243 I had purchased the 1224 cartridges for my tub but it looks like I needed 1248 for "Roman" style tube. Cartridges look almost identical but are slightly different with a larger waterflow opening in the metal body of cartridge. Thanks for your help!

I had trouble getting the small notch into the space. I used a red marker and placed a small dot on the blue extension and a dot on the brass fitting. I was then able to get it to seat into the notch within seconds. Prior to making the marks, I spent 5-10 minutes trying to seat the cartridge.

Hi. Everything going hood infill I got to the gray circular part!! It wouldn’t come out at all. Yours was so easy. We tried everything to get it out so we can bring out Cartlidge
