I'm trying to remove a cartridge from a 2570 Moen valve. It will not budge. What am I doing wrong? I removed the pin and then took pliers to try and remove the cartridge, no luck. Help!!!

You need a #1225 replacement cartridge. Pop the cap off of the handle. Use phillips screwdriver to remove the handle screw. Pull the handle off. Next, unscrew the two screws holding the cover plate on. After removing plate, there should be two integral stops, one on each side of the valve. Close the valves using a straight slot screwdriver. Pull on the brass cartridge spindle to ensure that the water is off. Remove the stop tube, which is a chrome cylinder at the center of the valve body. Look for a brass retainer clip at the top of the cylindrical portion of the valve body where the handle connects. It has a small hole and after you pull it out, you will see that it horse shoe shaped. Use your pliers or an awl stuck through the hole to pull the clip out. Note the position of your cartridge. There is a notch on the end of one side of the brass spindle at the center of the cartridge. Make note of its position. If you install it and get hot and cold reversed, just take the handle back off, and spin the brass spindle 180 degrees. The replacement cartridge comes with a white plastic tool designed to make removal easier. Use it. After loosening with the plastic tool, take your pliers and grab the brass stem. Pull as straight as you can. If cartridge will not budge, you might need a Moen cartridge removal tool. Do not spray with WD-40 or Liquid Wrench unless you like that taste in your water. If your clip won't go back on, it's because you didn't align the two ears on the cartridge. The ears should be at three o'clock and six o'clock. The cartridge must also be pushed in all the way. Good luck!

There is a plastic retainer not with two tabs used for removal. You will need a removal tool to get this retainer off. Any plumbing supply that carries Moen should have this tool.
After removing the retainer nut, the cartridge pulls right out. Good luck!

Remove the handle by removing set screw on the bottom of the handle. The screw is located under plastic button with the red and blue marking on it. Pull handle off and remove the retaining clip that is in front of the cartridge. Do this by holding the tab on the top with needle nose pliers and pulling up. Be careful to not break it as the new cartridge does not come with one. Use a pair of pliers to grasp the handle stem and pull out to remove cartridge. If you need to you can buy a moen removal tool and follow instructions to use.They have some very good easy to follow videos on u-tube that will show you step by step direction on what you need to do and helpful tips to make it easier. They explain themselves much better then I can. Try my moen.com. Thank you.

Moen cartridges require a Moen puller tool. Your local hardware store will carry this. You may not be getting hot water because there's a safety tab located on the cartridge that is preset during initial installation as an anti-scalding safety feature, and that may have worn, broke, or have shifted during time. Hope this helps!

You need to purchase a replacement cartridge before trying to remove a defective Moen cartridge. Always buy genuine Moen. If your valve turns on and off with a pull/push action you need part number 1225B, otherwise you need part number 1222. The 1200 cartridge will work in lieu of the 1225B but is more expensive and no longer used in Moen valves. There is a tool that comes with these cartridges which looks a bit like a white plastic cap.with notches on one end and a square head on the other.
Once the clip has been removed the only thing keeping the cartridge in the vslve is old sticky lubricant. Place the tool over the cartridge end and rotate as necessary until the notches are fully engaged and it no longer rotates. Using pliers or a wrench over the squared end, twist the tool back and forth several times. Remove the tool, and using pliers, pull the old cartridge out. Put the tool on the replacement part and insert it back into the valve. Lightly tap on the squared end to make sure the new part is completely seated, then use the squared end again to turn the cartridge as necessary to align for the clip to be reinstalled.

This is a common problem with Moen shower valves and fairly simple to fix. The pressure balancing cartridge is sticking inside. You need to remove the cartridge and clean it with white vinegar. The problem appears in valves that are not used very often - like in a guest room shower. The impurities in the water leave a varnish-like residue that causes the element to lock up and restrict hot water flow. If you are the original owner Moen will send you a free replacement cartridge but cleaning the one you have will do the trick. Once it's working be sure to run the hot water at least once a week. Here's how to fix it:
1. Turn off water supply to the house or at the PEX panel if you have one.
2. Remove handle by loosening the set screw at the bottom of the handle and pulling off.
3. Remove escutcheon plate by removing 2 screws on the face.
4. Remove escutcheon tube surrounding the valve by pulling with a needle nose pliers.
5. Using an awl or small screwdriver pry the retaining clip up and remove - DON'T DROP IT behind the tile!!
6. Using a pliers, pull out the cartridge. If it won't budge you can try some WD-40 or PB Blaster and if that doesn't work you'll need to buy a "Moen Cartridge Puller" (about $13 @ Home Depot) and it will come right out.
7. Shake the cartridge. If it does NOT rattle you've found the problem. Soak it in white vinegar for 15 minutes and try shaking it again and repeat till you hear the pressure balance element move back and forth. A shot of PB Blaster also helps.
8. Once the element is moving freely you can reassemble everything by working in reverse - don't forget to reinstall the retaining clip or the cartridge will become a missile! TIP: To prevent dropping the clip tie a string through the hole in the top and tape the other end to the wall. If it slips you can just pull it up. Also, spray a little PB Blaster in the valve body before inserting the cartridge to make it easier to seat it.
Hope this helps!

1- turn main house water valve off.
2- turn shower on to relieve pressure from the system.
3- remove handle by either popping center plastic cap off to reveal a screw or looking for a set screw on the underside of the handle. Depending on which one you have, then remove the screw.
4- once screw is removed, the handle should pull off.
5- the cartridge will be retained by a cotter pin like piece of metal. Usually takes some needle nose pliers to pull up to remove. Then take pliers and pull cartridge out.

Hope this helps and let me know if you run into any more questions.

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.

A stem is a cartridge in a real old valve. You have pulled retainer clip, you can try to pull it out with pliers, but you might need a moen cartrigde puller.

Sometimes they are very stubborn. Get a pair of pliers or channel lockes and pull straight up. Try wiggling the and pulling at the same time. This is the only way it can come out so you just need to keep working on it. Good luck!
