If it's shower-only, I'm very interested in the specs on the part that you end up using. I have a Moen in my shower (bathroom was built in 1985) that looks virtually identical to yours and I've been wondering what I'm going to do when I need to replace it.
Thanks
rockhound,
So I fixed mine today and it turns out for single-handle Moens where its pull out to turn on then one way for hot and the other for cold, you can use either the brass cartridge #1200 or the plastic cartridge #1225. I went with the brass one simply because it's an outdoor shower but functionally they're the same, so whichever you prefer. That also holds true for Moen single-handle bathroom and kitchen sink faucets that operate the same way. The only other things you should need are a monkey wrench, needle nose plyers, and some plumbers grease.
And, as the grizzled car mechanic would say, "well there's your problem right there." Busted seal. The brass fitting is sealed with standard o-rings that are easy to replace should they fail, so you might not need to get a whole new cartridge if the problem is leaking.
