I have a Toto Soiree which was installed about 15 months ago. Within the last 4 months it seems to have developed a condition in which there is a sound of water trickling within the blue type-B fill valve almost constantly. There doesn't however appear to be any water running into the tank or down the fill-tube to the bowl as a result of this trickling water noise. The one exception to the constant running is that the sound of the water stops when another water valve is opened, such as the bathroom faucet. The trickling noise will begin once again 10 - 15 seconds after the valve for the other water use has been closed. Is there any way to adjust this fill valve to stop this from occuring or does it need to be replaced?
