Toto Ultimate bowl level low after replacing fill valve
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?
Toto Aquia will not fill at all
I just replaced the sink in my bathroom along with both hot and cold water supply valves. To remove those valves, I had to shut off the water to my house. After removing them, I noticed that there was corrosion in both nipples, surprise surprise (the house has galvanized plumbing installed in the 1920's)! Got the sink working, but then, to my surprise, the tank on our Toto Aquia totally stopped filling after the next flush, and I mean not even a drop. Since I had just replaced two leaky valves in the wall, I went ahead and replaced the valve that fills the toilet as well. I cleaned out the corrosion, reapplied silicon tape, reattached the flexible supply hose and opened the valve. Still, nothing. I heard water entering the hose but it never made it into the tank.
According to my plumber, I am faced with the lovely Christmas eve chore of removing the tank from the Aquia just so that I can check the other end of the hose that feeds into the fill valve inside the tank. I am not looking forward to this, because Toto offers no instructions at all on how to service this model, not even to plumbers, and of course, they are closed for the holidays.
I imagine that this is not going to be as simple as using a screwdriver to remove both screws on the inside bottom of the tank. There are probably those nasty plastic nuts cemented on the bottom of the tank, which is of course virtually impossible to access without first changing into an elf. Anyway, my concern is that once I have the tank off, and I check the hose, if it is clear, I will not know what to do next. Is there anything about this toilet's fill valve that can be adjusted without removing everything? The fill valves of most toilets can be adjusted with a simple turn of a screw to modify the angle of the arm that attaches to the floater, but not the Aquia! Anyone have any suggestions before I remove the tank, knowing full well that I am going to have to put it back and risk creating leaks where none were before? If any one has a better diagnosis, second opinion or simpler solution, it would make a better Christmas gift than anything Santa could offer (other than a real live plumber who has got one of these in his own place...many experienced plumbers have no idea what they are getting into when confronted with the Toto Aquia and its lack of complete and accurate instructions).
Sure you all have better things to do than read toilet forums on Christmas eve, but in all honesty, Christmas probably gives the Superbowl halftime a run for its money on the national flush meter.
