I used a Korky universal fill valve replacment in my Toto Ultimate toilet. The replacment fixed my original problem, which was that the valve sputtered and shut on and off while filling the tank. However, the water level in the bowl is too low now after flushing. If I hold down the handle, the bowl fills to the normal level. The water fill hose is clipped to the overflow tube and I can see that water is flowing steadily into the tube while the tank if filling. But it seems like the water flowing from beneath the fill valve cap fills the tank before enough water flows into the bowl through the overflow tube. The fill hose is not kinked and water flows through it freely, so I don't think it is obstructed. Could this be because I used the universal Korky fill valve instead of the one made specifically for Toto toilets?
