Re: Bowl/Grommet problem, please help!
I noticed you mention this happened after cleaning. I assume you used water to clean the bowl, stem and grommet, or at least to clean the grommet. I've noticed that, depending on the bowl, a wet grommet will sometimes let the bowl slide off or a wet grommet will slide off the stem. I always make sure to use a dry grommet and make sure the stem and bowl are dry.
