Have tried three 1222 moen cartriges and they all have had a slow drip leak. The original one did not leak but had a problem getting to the hot water, the old cartrige was difficult to remove. Is there anywas to stop the leaking without tearing out the pipes behind the wall?

There could be some rubber particle, or debris from the old cartridge still in the body causing the leakage, or you may have damaged the valve body when removing the old cartridge. If theres damage to the valve body then replacement is the only viable option. Remove the cartridge and carefully examine the bore to see if there's any nicks , gouges or pieces of the old cartridge.

How did you get that "difficult" cartridge out of the valve body?

Before you installed the new cartridge, did you use a 3/4" (for the older moen valves) to clean the inside of the valve? Sounds like that could be your problem.

thanks for the insight. I took it apart examinind inside, no rubber, some small scractches. Cleaned again with a toothbrush, and used plummers grease on all of the rubber parts. The leak is now a little less than a drip a minute. Only had a small amt of grease, thinking if I had used more grease maybe I wouldnt have the drip?

pried it out with two small screw drivers place on each side. There was a lot of rubber that tore off and I removed that needle nose plyers. Prior to realizing that the rubber was parts of the old gasket i used a screwdirver to try to scrape away the rubber (did no at that time realize what it was) and I am thinking that I scratched the surbace of the inside which is causing the leak. I did replace again using some plummers grease, which did slow it down to a drop a minute.
