Repair Shower faucet: Moen Posi-Temp Shower faucet ( 1222 B ) 

Excellent video!! Mine turned out to be a bit more difficult. The cartridge would not come out even after using the white plastic tool to break the seal. Then while pulling with my pliers, the metal stem broke off. So then I was in panic mode because the shower was in the "on" position, and I could not turn the mains back on. To overcome that, I screwed a short screw into the center of the cartridge, where I could use a screwdriver to turn on and off the shower faucet temporarily till I figured out what to do. I finally ended up drilling 2 long deck screws into the plastic face of the cartridge in the 3 o'clock and 9 o'clock positions and used my pliers to yank on them repeatedly. After many hard pulls, the cartridge finally came out. Turns out the black rubber gaskets on both sides of the cartridge somehow got caught in the inlet holes of the copper pipe. They tore loose when I pulled out the cartridge, so I had to remove the rubber bits with some needle nose pliers after taking the cartridge out. Just wanted to share my experience, but I appreciate your video!

Excelente explanation👏🏼👏🏼

The piece that holds the handle in place was replaced with plastic, worst decision ever made because after awhile the plastic strips and you can’t turn the water off with the handle

2:56 I'm no plumber, but I don't need these things (instructions). I fly by the seat of my pants baby!

anyone have an idea why my shower handle only turns 90 degrees when its suppost to turn just like in the video 180 degrees ?

4 years ago, but what saved me in this video was how to align it before reassembly. I had it all wrong and it was acting strange. Thanks for the video!

Dad jokes and some clear, useful advice. What more could you ask for?

This was so corny I couldn’t stop watching 😂 This is also the best video I’ve found to replace that valve! My shower has been a trial for the past couple of days, but after watching your video I see where I went wrong and know what to correct. Thank you so much!

THANK YOU!!! I was at wits end in the final stages of replacing a shower cartridge using trial & error trying to position the center shaft properly so that the water was OFF when the handle was in the OFF position. You pointed out the "Small notch facing up, means on" turned a frustrating puzzle into a piece of cake. Thanks again!

Love this! Thanks for helping me solve a 6 yr issue.

You saved my life! My wife was going to kill me if I didn’t get this fixed this weekend, Great video!

Omg! Your video has saved me, after my faucet wouldn't turn off! Also, another video had a tip to heat up the cartridge, with a blow dryer, if it refuses to come out. Next, Moen has a program, where you can go the hardware store and get a new cartridge for free! Thanks so much! 🤗

Thanks for cheering this video

Thank you man, I was struggling to figure this out after my landlord kept delaying coming by to fix this. You're a lifesaver!

I hope you had some whipped cream to go with your humble pie, great tutorial, thanks!! 😊

I love your vid made me laugh

Str8 to the point. Fixed mind using your instructions. Thank you! You saved me a lot of money.

Thanks for the laugh during my frustrating project!

I have a single handle shower, but I'm unsure if it's a Moen or not. Is the 1222B a universal cartridge?

I just wanted to say: thank you! Your video was incredibly helpful. I appreciate your willingness to share. You saved my Sunday

Buddy, I LOVE your explanation: " I FLY BY THE SEAT OF MY PANTS!' an' 'at's duh way to do it, bro' !!!

I am getting low water temp from shower, so I will put new 1222B. To measure the temp of water coming in, do you know how can measure without the 1222B. What is the name of the plumbing assembly that the 1222b goes into, so I can ask home depot also

I've replaced several moen cartridges and those problem but now I have a new problem hardly any cold water comes out all of a sudden, I replaced the cartridge again and the problem continues I don't what the problem is and I don't want to replace the valve, too much work involved if I do that.

Great instruction coupled with some humor. Love it!

sorry i meant what size isthe philips screw driver size that you use to remove the screw in the adapter, thanks!

A wrench? That sir, are vice grips

Thank you very much I like to do things myself I don't want to have to call a plumber I just like to learn to thank you😊

i have the same problem but will this solve my hot water issue not alot of hot water comes out ? thanks

Thanks

Would somebody please tell me which direction to turn the hex wrench?! I know left to loose doesn't always work, and since whoever put mine together obviously used a torque wrench, I've managed to strip mine trying to get the thing out. I don't know if I'm tightening it or loosening it.

Thank you. Ended up removing the plate to get to retainer clip. Also bought danco puller from home depot to remove. Took 30 mins total. Thank you!

Ours is horribly stuck. We bought the puller tool and even that hasn't worked. I busted out a climbing harness and rope to try to get some more force on it to no avail. 😭😭😭we really stink and need a shower

Thanks.. it was really very useful.. my husband did it while looking your instructions on RU-vid 👍

You didn't explain how the temp limit stop can be adjusted :(

You just might be the only person in the world who was able to remove the cartridge without having to use the puller tool.

My faucet in the shower is dripping 💦 do I have to replace the part? I have a similar faucet a bit outdated.

what if the handle doesn't come off after the set screw is out? Just ran into that issue, haven't had it before... just pull harder or what do you recommend

You pulled the cartridge out and I see two 0 rings front and back; but when it goes back in, there is but just one 0 ring in the front??

"Don't go there girlfriend." 🤣🤣💀 Suscribed

What if the clip is further back and cover or blocked by the plate?

Just installed the new 1222b But I have no pressure on cold water & when I put it in off position it leaks

Nice step by step... but lube up that o'ring too ! Good video shooting.

what size screw driver to use in removing handle adapter screw?

Great video. Very well filmed up close.

I replace it and still have a very slow leak. And suggestions?

I need a cartridge, but how to call Moen, someone have the number please

Is there a way to know the size without taking out the old one out?

Close the tub drain before you start taking the faucet apart.

Did you check if the water had the same level of wetness as it did before?

Do you have to have the water turned off to get the handle adapter and the key stop off

Why doesn't yours have the 2nd o-ring on the cartridge?

Guy how could I know the model of the cartridge?

Good joke about the screw loose, I''m going to borrow it!

I followed all the instructions. Now the rotational range of my shower handle is only 180 degrees. I swear before I started the project it was closer to 270 degrees. Similar to the range of the shower handle in the opening of this video. Anybody know what I did wrong?

Thanks for the teaching, Sir This is all the answers and I'll be done soon with my new walk-in shower. Great job, Thanks

Where would I turn the water off? Somewhere in the garage?

Very good video! Thanks! I was able to pull this repair off with your advice and instructions. I would add that if you’re a novice do it yourself plumber like me...invest in a cartridge puller if you have hard water! And if the pipe on your water mixer is a bit built up with hard water deposits...hit it with limescale removal product and soak for a bit and even use petroleum jelly to reinstall the cartridge because it’s a tight fit in the pipe my cartridge only came with one lubricant packet and it just wasn’t enough...but it worked perfectly fine after following the instructions on this video! Thanks much! Have a good day! I will have a good day now that I have hot water in my shower again! lol

This video is the BEST!!! Very well done. Love it. Very helpful. Thank you!

It is worse putting the little clip back…

,

Excellent video. Thank You

Very good video and great sense of humor!

Not only did the stem brake but so did the front plastic portion of the cartridge. I can sort of grab onto a metal exposed portion but it’s not giving. Tried turning the water back on and nothing. Yeah... pretty furious atm

Thank you so much for your video.😊

Good video! Does the Keystop play a role in the water pressue!?! Ours is not pushing water with enough pressure ,specially when I have to move it to the MIDDLE to avoid getting burned! What is the remdey?

Add some fishing line to the clip to save it from getting lost. If it falls behind you can pull it back up. I wish I did that with my wedding ring - lost it and never found it.

You sunk by battle ship😂😂😂😂😂

It looks so easy and maybe it is so easy but I have spent all day and unable to do it. In summary. I removed cartridge and replaced with after market denco which failed. Replaced with 1200 meon which looks same as existing one but shower is leaking more. Is this one different than 1200 ?

I changed the cartridge and everything went back together perfect, yet I still have a drip from the shower head. What else can I do?

Hi, I replaced the cartridge.,I get hot and warm water. I do not get just cold water. I have tried another cartridge with the same problem. Do you know how to fix this issue? Thanks

You're the man. This is the best video I've found on this topic!

I just replaced a moen/ danco tub and bath trim from lows, and the problem I have is that the handle is still loose after I installed it, what did I do wrong?

What happens if you replace the cartridge and you are still not getting pressure on the hot side??

What happens when u put the screw that holds it all together but when you tighten it the whole assembly turns with it?

My handle adaptor is stuck...do you have a tip to remove the handle adaptor? I took out the screw and tried to pull on it with pliers and it will not budge?

But how do you adjust the temperature?

This is a BEST video about the subject. The video quality is great and your presentation is absolutely awesome and entertaining. Great job 👏 👏👏

Tried calling moen just now and says three hour wait!!!

Thanks

Thks much I was struggling.

I don't think not wanting to being scalded is exclusive to elderly or toddlers lol.

Excellent. The problem shown is exactly my problem. Have to order the cartridge.

i just installed one of these , when i turn to left i get hot and right i get cold but they dont seem to be mixing , seems one cuts off when the other is on , any ideas ?

Good video and love the humor with great explanation.

Thank you so much Paul. If it was not for your video, I would never have attempted this myself. I'm happy to report that I replaced my old cartridge and that the pressure is back to normal. I wish to share my experience with others. I hope this will be helpful. My shower had lacked pressure for a good 10 years. Even more in the hot water position, just like in your video. My Moen posi-temp was installed by a plumber 25 years ago. I I had checked everything else regarding the plumbing and everything was okay. After viewing your video, I knew the problem was with the cartridge. I contacted Moen and they sent me a new cartridge, free of charge. I had many concerns of doing this myself since the installation is 25 years old. Everything must be tight (and it was ultimately). Anyhow, I proceeded and followed your video and the instructions that Moen provided. Moen strongly suggested a flush of the pipes, hot and cold, once the cartridge was removed. I did this and I know it was helpful. Everything went easily except for 2 things This is what I wish to share. 1) It was VERY DIFFICULT to remove the old cartridge. Moen suggested a 1/4 turn clockwise with the plastic tool they provided with the new cartridge, to loosen it and remove it. This did not work easily. I yanked it in both directions for a good 45 minutes before it started to loosen. Many times, I thought of giving up. I was afraid of breaking something since I was using a lot of force. Despite these difficulties, I managed to loosen and remove it. I then performed the flush. I was now ready to install the new cartridge. 2) Installing the new cartridge proved to be EXTREMELY DIFFICULT. I put the grease on the new cartridge as indicated. I was able to insert it about 75% of the way with MUCH difficulty. it took close to an hour to make it to 95%. I was pushing on the cartridge, as indicated in the Moen instructions, with my fingers. Many times, I thought of giving up. The cartridge must be fully inserted in order to reinsert the locking pin. After too many attempts with my fingers to go from 95% to 100% insertion, I had an idea. I used my visegrip tool for an extra push on the cartridge. Please be advised that I'm not sure Moen would 'endorse' this approach. One part of the tool was pushing on the top of the cartridge and the other part, on the bottom. This extra force enabled me to insert it completely. I think that maybe I should have greased the inside of the pipe. Maybe it would have been more easy. I completed the work. Everything works just fine now. Thanks for reading.

What does the moen cartridge exactly do? Only regulate water temperature? Does it open the water flow too? Because the stem from my Old cartridge spins both ways but don’t open the water flow. Not sure what exactly I need to replace. Help please.

Thanks for your video. It allowed me to fix a metal shower handle that came off. The handle adapter screw somehow was behind the handle adapter inside the metal handle. I unscrewed the outer metal handle screw with a very small straight head screwdriver. That allowed me to remove the black handle adapter that was inside the metal handle. I could hear a loose part when I shook the metal handle. That loose part was the handle adapter screw (1:16 of this video). I was then able to attach the handle adapter with the handle adapter screw back to the stem assembly and reattach the metal handle onto the handle adapter with the handle adapter screw. Without your video, I wouldn't have figured it out myself. Thanks again!

Super helpful! Love this. Thanks Paul!

Great, vid, exactly what I was looking for (a description of each part!)

Thank you for this awesome and extremely informative content very grateful!

We just fixed our shower easily because of your video! Thank you!! Unfortunately, we had to buy new parts (rather than get for free) because we bought the house with the moen parts already installed, but we saved the plumber fee! Thank you very much!

Awesome tut, best on YT & it fixed my problem of water turning on in both directions...

This video was great informative and hilarious as well😂
