Re: replace new moen 1200 stem, still leaks due to...
The proper fix for this is to hone out the scratches
take steel wool and wrap it around a dowel or piece of wood or ust stuff it into the housing and turn back and forth to smoth out the scratch
if the scratch is real dep you wll have to go to harbor freight and get a honing tol that fits on the end of a drill
the stem should have some type of crown washer that you should be able to get an assortment from lowes , ace or hd
If you are asing for a recommendation for a good silicone I always use GE silicone it is the best
as a last resort (if nothing else works to stop leak
I would take cartridge wall and streatch teflon tape as tight and smooth as possible to block water coming up between housing and cartrideg this is not recomended by mfg just a spa (my initials) certified suggestion

Moen makes a stem removal tool that angages the 2 ears on the outer portion of the stem. You can order from Moen: http://www.moen.com/moen/cartridge-removal-tool-for-1200-or-1225-or-1222-cartridges/_/R-COMMERCIAL%3A104421
Or your local home center or hardware store should have one in stock if they carry Moen parts.
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...
I'm not now nor have I ever been a fan of the plastic moen replacement cartrideges. I don't know if they still do but probably about twenty five years ago I tried using a few of the plastic replacements,mostly due to high cost of the brass moen factory ones I think every one leaked. Then I actually read on the instructions that it was not unusual for them to leak some. My suggestion is to get a good brass moen magnum cartridge and be done with it for another twenty years. Hope this helps you. Thanks.
If you are referring to a Posi Temp cartridge they can be tough to remove from the valve body but there is a specific Moen 'puller' tool available. Basicially, once the 'U' shaped brass clip, which holds the cartridge on place is removed, the old cartridge (including the brass stem) will pull out completely. However they are frequently stuck in place and require some force to break free. A small plastic tool is included with the new cartridge - it isn't worth much, IMO but at least try it. Slide it over the stem so that it fits snuggly against the old cartridge and twist it with channel locks or crescent wrench. You may be successful in getting the cartridge to turn, one it does it will usually then pull out. Grasp the brass stem with vise grips/channel locks and pull the cartridge straight out. If it doesn't budge, you will likely need the specific tool mentioned above which screws into the stem (where the screw for the handle would normally fit) and is tightened down against the valve body. The pressure applied is similar to an auto. brake puller, pulling the valve out. Be careful in exerting any pressure against the valve body because it may not be adequately fastened to blocking inside the wall cavity and too much or excessive pulling may cause damage to the water supply lines.
Make sure before the install the new cartridge the valve body is clean and free of any build up. I usually take a little emery cloth and clean it out then flush the valve with water. Also use plenty of additional silicon/plumbers grease on all the black rubber seals before inserting it . Make sure it is not upside down and fits into the valve body all the way. The brass retaining clip is then re-inserted. Be careful not to lose it as a replacement is not included with the new valve and may not be easy to come by. Good luck!
You need to replace the valve stem. Turn off house water, locate and loosen handle set screw, remove cylindrical cover, and remove retaining nut to access stem. Take e stem with you to a home store or plumbing supply house for accurate relacement.
Once you have removed the U shaped cotter pin whis is brass in colour. Use a pair of plyers and hold on to the brass stem. you will need to pull fairly hard to remove. If you have the white or black stem loosening knob which comes with the replacement cartridge you can insert that into the brass cartridge where the plastic sides of the cartridge are showing. Turn your plastic konb clockwise to loosen the cartridge and then pull out.
You are not the first. Usually you must break the plastic handle to remove it and then you can access the screw and have leverage to hold the brass stem with pliers while you try removing the screw. Caution, do not try to bend the handle to break it off or you will break the brass facet stem. Also, there are two styles of handles: one has a short innercone,the other has a longer inner cone. You need to know this before you purchase a replacement. Goodluck< Macgivor
If the clip has been removed it will come out. these things get incredibly tough to remove. Moen does sell a little puller just for these. I have used a socket with the screw in the stem to act as a puller.
If you have the water off AND your sure your have the correct new cartridge you can give the valve a little heat to help soften things up a touch. Use a heat gun with caution
