How Do I Remove Cartridge From Single Handle Moen Shower Faucet To Replace Rubber Washer?

Just went through this. The cartridge came out, but the sleeve stayed inside the copper.  After trying to work the sleeve away from the pipe walls with a flat head (and scoring up the copper in the process), I ended up having to cut out the valve and solder in a new one.  A bit of a pain for a job I thought was going to take less than half an hour.

I was able to resolve this.  The whole cartridge assembly inside the valve comes out easily, but you first have to rotate it a quarter turn (90 degress), after removing the retaining clip.  There is a special tool for this included when you purchase a new cartridge.  If anybody else is considering fixing the same type of faucet (Moen single handle), then I don't think there are any user serviceable parts on the inside, like rubber washers, so just consider replacing the cartridge.  There are rubber washers on the inside .. But there are quite a few, and it's much easier to replace the whole cartridge than trying to find and replace the different washers/O-rings/rubber pads.

Thanks for your kind words, and I'm glad you got your hot water back. There is a related issue with these Moen cartridges I posted about on another similar question. It seems you can put the cartridge in upside down (rotated top-to-bottom 180 degrees). What that does is reverse the hot and cold water! It's an easy fix -- remove the cartridge, rotate it 180 degrees from where it was, and re-insert. It is hard to figure that one out, given that the hot & cold water come out the side!!!

i followed the MOEN instructions but the plastic cartdrige only comes out about an inch. Seems as if a rubber part is catching on the valve unit or because things may be airtight it's like pulling off an air tight plug.
The instructions say 45 degrees but the cartridge will not come out. I'll tried 90 degrees and that definitely loosened up the cartridge.

I'm sure I had to rotate my valve 90 degrees (quarter turn), not 45. About the only thing I can think of why your cartridge won't come out fully is that it is snagging/hanging up on something, like: 1) One of the rubber washers have come loose and snagging in the hot or cold water intake line or one of the O-Rings came loose or bulked outward, like you thought of, 2) If you have real hard water, there might be a mineral buildup on the valve on the valve some where.

This just happened to us the sleeve staying inside the  copper pipe. You will need a vice grip an and easy out! My husband worked on this job for about 3 hours, getting fustrated, finally got these two tools and the sleeve is out. Now I can look forward to a better saturday!

Keep in mind to rotate the easy out left and right til it is loose, there will be build up between the copper piping and sleeve then pull straight out

I tried 90 degrees and still no luck getting the spool out? Any idea? Is it stuck, I'm pulling hard I'm afraid to break the copper pipes?

Sorry if I am not posting right.  This is not an answer but rather a question.  Anyway, I have a slightly different issue than what I have read above.  I have managed to pull the cartridge out (by using a puller tool that screws into the valve stem and then sinch the large nut up against the end of the pipe).  What happened next was the main part of the cartridge came out but the out sleeve still remains stuck inside.  Any tips on  how to remove?  Without degrading the inside of the pipe making eternal leaks quite possible?
