“I ordered two of these on different days the first one arrived in a open plastic container no instructions on how to install it and missing the lubricant. The on off function of the valve seems a bit loose would easily turn the water to hot or cold if accidentally bumped not good in the shower. The second one works fine it came in a sealed plastic container with all the instructions and lubricant for installation.”
“Once you figure out that all Moen twist-to-on use the 1222 and it is the same as the 1222b, you are set. Except that the instructions are a set of pictograms that say nothing. Studying them hard, you may figure out a few things, but not enough, so you call the help line and find it will be a 2 hour wait time, which turns into 3 hours. You'd think if you had that many people asking how to do it, you'd re-write the instructions. Years ago my job was editing and re-writing equipment manuals and maintenance procedures so that they were usable. There are some pretty good videos on line, but don't cover it all.First you would realize that when the handle is getting hard to turn (deposits in the interior), it will start to loosen the seal between the cartridge and the valve body, so it will start leaking.When taking it apart, you need to take out all screws, take off the face plate and collar to get at the clip that holds the cartridge in. This will be behind the wall. You will need needle nose pliers. Do not drop it behind the wall, since they don't include a new one.Note how the old cartridge is installed. That, in most installations, will be with the HC on top and the little notch will be in the bottom big notch. that is how you install the new one (some installations will require this upside down).Ones the clip is out, do not try to pull the cartridge, or you may break it inside. You must twist it with the plastic piece that comes with the new cartridge. With enough mineral deposits in the body, that may take a lot more pressure than you think. That twist will loosen the cartridge in the body and begin to pull it out. Once loose, you can pull.NOW, reach in with your fingers and check to make sure the body cavity is smooth and free of mineral deposits. It it has any, the new cartridge will not seal. Grab a green scotch-bite pad and reach in to clean off all deposits, then wipe or rinse (hard, since you have to go turn on the main water and rinse water will probably go behind the wall). Finally, lube the inside of the valve body and the exterior of the rubber pieces on the cartridge, then insert the way your original one was and insert the wire clip without dropping it.Reassemble and test. Good luck.”
“Since it's supposed to be the replacement, I'd be surprised if it didn't work. However, the shaft seems just a few mm shorter than my original, so my handle now scrapes against the wall plate when installed.”
“This was just what I needed. It was extremely hard to remove the original cartridge. In the process, the original cartridge broke in half. I had to cut and scrap to finally get the other half out. Putting this in was a little hard, but in the end I got it to work. Overall this is just the right product for my leaky bath tub.”
“cartridge installed perfectly no leak after couple of days, will buy againold cartridge seized up real good and wasn't coming out, i was able to use the white adapter came with the new cartridge to loosen up the old one and take it out after a few minutes. Trick is to force the old cartridge back and forward and repeat (don't expect old cartridge to move very much right the way), it will eventually loosen enough you can pull it out”
“We are in a new build community, and everyone I talk to have an 1222b that broke within less than 3 years. It brakes in an open position and there was no way to turn off the water other than having to replace the cartridge. I opened the cartridge and noticed the inside part of the cartridge breaks very easily because it is made out of plastic.There is an 1222 HD version which all the plastic parts have been replaced by metal and it is not much more expensive.”
