    I have a leak in the area of a Grohe shower valve. Is there a way I can confirm it's the cartridge before I replace it? This valve was purchased/installed in 1994, so no warranty replacement. The leak is very slow and seems to be worse when my son showers, I can't figure out why. Could it be anything else than the cartridge? Is there a way to visibly check it?

    Take the handle and trim off, then install the handle so you can turn things on. You might try calling Grohe, they may send you a new cartridge for free. That policy changed over the years, and yours may be before, but it doesn't hurt to ask.
