Cartridge was replaced in my delta 1400 now the shower doesn't turn off at all . Started was dripping now with new cartridge am I doing something wrong. I have tried 2 new cartridge
Was it a moen, or delta cartridge? They're not interchangeable.
Delta 1400s are really straight forward to replace. So long as the valve body is clean and smooth inside, there shouldn't be a problem. Can you see any damage inside there?
Are you saying you put a Moen Cartridge in a Delta valve? As others have said, that doesn't fly. You need to find the cartridge specific to the Delta 1400.
Or did you mistakenly put Moen in the title when you meant Delta?
