Replace the cartridge for a moen shower

There is a special tool that yo can use to remove an old and stuck moen cartridge and they can found at your hardware store. Now before you remove the cartridge be sure to remove a small brass or copper pin located at the top of the stem. you will see a groove in the stem cover where the pin is located. once the pin is removed hookup the puller and remove stem. sometime you are able just to grab the stem with a pair of pliers and give a good pull and twist to get it out. don't pull to hard to damage the plumbing in the wall. good luck and I hope I was able to help. As always, TURN OFF THE WATER FIRST...

if cotter pin is already out just jiggle and pull (with muscle) creates suction which is why its hard to pull out..but it will come out..

Call Moen directly. They will ship what you need to your door, for free.

hi, there is a lock nut that holds the cartridge in this will need to be unscrewed, if you have already done that it should only be a matter of pulling it straight out, sometimes the cartridge gets seized in the body of the tap use mutli grips or pliers to pull it out by the shaft that the handle goes on

The old MOEN single handle faucets like youve described usualy took a 1200 or 1225 cartridge. Both are available at most of your big home improvement stores. The answer to your question is yes MOEN parts are still avail. Hope this helps. If this advise is helpful, please give me a vote.

New moen cartridges for tub/showers come with a handy white plastic tool to aid in old cartridge removal. One end is squared off for a wrench, the other is slotted to place over the old cartridge in the wall after the clip has been removed. Place onto cartridge and use a wrench to turn several times back and forth. Remove , grab the stem with pliers and give a tug. You want either service part #1225B (pull/push to turn on) or #1222 (just turn knob counterclockwise to turn on. Get the replacement before you proceed.

You are on the right track. You have to use some force when pulling the stem from the faucet. Your replacement cartridge should have a little black or whit cap. that is inserted on top of the cartridge and by turning the cap will help loosen the whole cartridge

there is a little plastic tool that comes with a new cartridge....you use it to turn the cartridge back and forth....breaking the seal that has formed between the rubber on the outside of the cartridge and the inner wall of the valve. After doing that you should be able use a pair of channel locks to pull the cartridge out.

hi... yes that's a very common issue with moen "cartridges" -- it's very simple to fix..... grasp the handle and give it a gentle tug upwards when the water is on... if it retracts again, pull the handle out again and tug again but this time a bit harder. Not sure what causes this on new cartridges but it will fix your issue.

make sure when you turn on the hot and cold shut off valves all the way and turn the moen on after that. Some times I would get that problem if I turned one(either hot or cold) off then tried the shower.
