All that you should need is a replacement cartridge that you can purchase almost anywhere. If your faucet pulls out and turns left and right, you would need a 1225B cartridge. If it just turns it would be the positemp model and tha would require a 1222B cartridge. Once in a blue moon a cartridge puller will be needed, but not that often. The genuine cartridge does come with complete instructions also. Only use genuine Moen replacement parts.

Thanks... It was easier than I thought. now I am ready for bigger tasks.

I can not get the cartridge to come out. I have the pull and turn type.
