I've got a ca 1997 Toto low flush toilet with a problem. The splash
block/water level in the bowl is low, leading to excessive soiling of the
porcelain. Worked fine up until a year ago, when I had to plunge it
repeatedly for about a month. The problem wasn't line blockage, it was a 4
year old who was so pleased to have learned the skill of wiping he, erm,
overdid it. ;-)

His lordship also practiced his skills on the upstairs toilet, a ca 2000
American Standard Cadet, with the same results (pretty much lived with a
plunger in my hand for a couple of weeks . . .)

The Cadet's splash block/water level is fine but the Toto's isn't. Any
ideas about how to restore the water level to a near normal? Right now it's
about 2" above the throat of the flushway, providing a splash block about
6"x6", which is entirely inadequate.

Thanks

Marc
