Have a Toto Caryle 874 toilet. It operated fine for several years, but now the water fill mechanism is causing overfilling of the tank. This causes the excess water to flow over the vertical overflow tube, which causes continuous water running.
It is not the flapper, as it was recently replaced.
The dealer said to remove the white tab on the vertical mounting tube that the blue fill mechanism device is mounted on, then rotate the fill mechanism device counter-clockwise until the water stopped (then replace the tab). This helped for about a week, but now it has started the same problem again. The fill device is now rotated fully against the wall of the tank, so further adjustment is not possible.
Any helpful comments would be appreciated.
