After reading the good Toto reviews I replaced 4 toilets with them. Well the problem with dribbling fill valves that was covered on this forum last year, is still continuing. I have the G-Max valve with adjusting screw and they are leaking like your earlier reports. This is the end of 2008 and I'm angry that these toilets are still being sold with defective fill valves. The leak is quiet and I've just discovered it after 6 mo. of loosing water.
