Moen Posi Temp Handle Tub and Shower Only Configurations Faucet Replacement Cartridge, 1222

My old MOEN shower valve started to become very difficult to turn off. We have hard water, so I suspect calcium buildup. I suspect that if I didn't replace it, it would either begin to leak or stop working altogether. I was concerned about ordering a replacement because I read all the reviews of people buying aftermarket replacements that didn't fit or started leaking soon after installation. So I was looking for a brand name replacement. This one was a little more expensive than the no-name aftermarket parts, but worth it. Removal of the old one was quite difficult. It seemed stuck in place. You have to spin the old valve 45 degrees to remove it. I was glad ai also purchased the removal tool. I had to use channel lock pliers to twist it back and forth when removing to get it to come out of the valve body. When I took the old one out, the rubber crumbled. It appears it had hardened from years of use and I think it was difficult to remove because the rubber gasket was stuck inside the channels inside the valve body. Once I was able to get the old one out, I cleaned up the inside of the valve body using an acidic shower cleaner to remove any calcium and lime build up. Installing the new one was fairly easy. I used the included silicon lubricant packet and applied it to the new valve and also around the interior of the valve body. Installing the new one required a bit of light tapping with a hammer (do not tap on the brass stem - there is a plastic piece included that fits over the brass stem and rests against the plastic body of the valve - I was able to make a wood tap block by drilling out a hole for the brass stem). I lightly tapped on the valve body to set it and reinstalled the retaining clip. The only issue I had was that the instructions were unclear as to the position of the brass stem. The first time I installed it, it was upside down (reversed 180 degrees), which means the shower was running when I turned the water back on. It was a simple thing to spin it 180 degrees to make it operate properly. I'm very happy with the quality of the replacement and it works 100% as designed. Now my shower is easy to operate and is no longer difficult to turn off.

Bought it to replace my leaky cartridge that didn't supply hot enough water either. Works great, no leak, and I can have water as hot as I want.

First of all, I should have changed the old one at the first signs of it going bad. The white lime deposits or whatever you want to call it is what causes the problem. You will notice the black side rubber pieces, when you try to remove the old cartridge, they can get stuck in the internal slots inside as you're pulling it out. Once that happens you're going to have a very hard time getting it out. In the long run my old one snapped in half. I had to break it out in small pieces being careful not to scar up the inside of the housing. All that said, I didn't have a cartridge puller. They sell an all brass 1222 replacement cartridge claiming it will last longer. First of all the plastic housing of my old cartridge didn't fail. Those rubber inserts started to catch in the internal slots. It actually stopped turning when I tried to get out of the shower leaving me standing ice water to get it stopped. Since my old cartridge was plastic I was eventually able to break it apart. If it was the brass cartridge it would still be in there with the rubber pieces folded over making it impossible to remove. There is not enough clearance for it to come out if the rubber gets doubled over. Even with a puller. The brass cartridge sounds like a great idea. But not if it gets really stuck like mine did. You can not break it into little pieces to remove it. You'll have to buy an entire new cartridge housing. About $100 Now if I wanted to use the brass cartridge you would have to change it at the very first sign of trouble. I don't know if they sell just the black side rubber pieces so you could change them. But if they don't you're going to have to buy a cheap plastic cartridge just to get them. So what did you save? I will just keep on using the plastic cartridges. Keeping an eye out for the first signs of failure. My new plastic one works as smooth as hot butter. I'll be buying a cartridge puller. And a spare plastic cartridge. I won't be waiting until I can't turn it off to swap it out. I should have changed it a year or two ago. Especially now that I see how it works and how it can fail. Plus it's a pretty easy fix. If you don't have to destroy the old cartridge to remove it. One more thing as mentioned in another review, buy some silicon lube and coat it real good when you install it. And maybe as a preventive measure, pull it out once in a while and lube it up again. 3 Phillips screws, one Allen screw and the retainer clip. Pull it out check the condition of the rubber side pieces and smear it up, and put it back in. Very simple job if you do it before it turns into a nightmare.

The good is this cartridge works with no issues. The annoying part is the first one I ordered, the grease pack leaked out in the package so I returned for a new one. The new one also lease all the grease out of the packet. Fortunately after splitting the packet open I was able to get sufficient amount to finish the job without buying plumber's grease at Home Depot. Still annoying that it happened twice to me.

Easy to install. I ordered unit and remembered that there was a temperature adjustment. My unit was not leaking so I just adjusted water temp. a little higher. I kept the new cartridge for backup. Moen remains a great product.

Went on Youtube and found two relevant videos on the topic from: "Check It Out !!!" and "Stephanie Vandaelle" Cartridge is about 20 years old in a building that has a lot of mineral in the water. So lots of build up and really appreciate how long it's lasted. Shower handle fell off because the rod or stem was pretty much rotted away. Unfortunately rotating it with the plastic removal tool only helps to loosen it a bit but not by much. Couldn't use Cartridge Removal Tool, the metal one, because the stem or rod fell off and you need to screw on to that to be able to pull it out. Tools: Adjustable Wrench Drill and Drill Bit Any long wood screw Pry bar Wood plank or Long Metal Rod to Brace against Tile Cutter to mark and make drilling easy Manual Screw Driver Heatgun or Hair Dryer Actual work time: 12 mins Looking for my disorganized tools: 45 mins Disassembled shower handle until I could access the shower cartridge and manifold. Turned OFF water via manifold (usually counter clockwise until it stops). Apartment building here so if your water shutoff might be in a different location. Drilled bottom of cartridge, the plastic part. Easier if you mark where you'll drill with a cutter so the drill bit finds purchase otherwise it'll slip around. Make sure it's straight as possible to not damage the pipes. Make a judgment call on whatever size you want based on the wood screw you plan on using. Makes sure it's not too big. I used a random wood screw that long enough to pry off of. Used a cheap $10 heat gun on the pipes until it was warm. Used plastic tool to rotate slightly ( not completely since the top of the cartridge hits the pipes and can only be rotated 180 degrees once it's actually out) and loosen cartridge clockwise. This absolutely helped to loosen the cartridge almost right away. No struggling at all. Things would have been worse without it. Used a manual screwdriver so I could better control the force on the woodscrew. Damaged pipes are more expensive work so be patient and careful. Then used prybar on the woodscrew. Metal rod or wood plank to brace on tile ( and protect tile) and leverage prybar off that. Do it SLOWLY and CONTROLLED and do not yank agressively. Be careful not to go ham as to not damage the metal pipe. Used heat gun again when encountered resistance in pipes. Once head of cartridge is stuck and no longer embedded in the pipe and have room to turn, I switched to the Moen Plastic Removal Tool and an adjustable wrench. Didn't need to yank it out after that just did a back and forth motion mostly going clockwise. Voila! Cartridge came out easy. I am thankful to the Youtube videos for such a great idea and my humble and mighty heat gun for helping a STUCK cartridge with a BROKEN STEM so easily done in less than 15 mins. By the way, the shower handle position will be in the middle position. So you might want to move it clockwise until it closes so you don't get a burst of water from the tub faucet once you turn the water back on. I completely forgot about this and found out the hard way. Talked to a retired handyman and he said once you encounter a good deal of resistance in the shower handle, should be a good time to replace the cartridge. I think I will take his advice from here on and save myself so much trouble.

Update: returned first one and replacement valve works great! Easy return Bought for a tub that is rarely used. We keep the drain plugged in the tub and after installing this valve we have water pooling in the tub.
