I had a fairly heavy leaking in the upstairs bath/shower which is about an 11 year old house. It was showing wear so I bought a new Moen spout/handle set which included the Moen 1222 cartridge. Old cartridge required a puller to get out. Didn't see anything unusual in the cartridge pipe. I replaced the cartridge, but not the whole valve unit. Now no leak when using the tub spout. But when I pull the diverter and use shower, it is still leaking. Any ideas? Could the pipe the tub spout fits on be loose at the valve? Does it just twist off? Any ideas on what to check next? I cut a small hole in the lower bath to see up into the upper bath.
