I have a need for some advice.

I closed the supply line shutoff valve to the toilet this morning. Just wanted to clean the bowl. (I should have just left it alone)

But when I opened the supply valve back up, no water is filling the tank? I tried several times to open/close/open, and the first few times I opened it I saw/heard a tiny amount of water enter the tank. I also heard a vibration/hum in the pipes if I opened valve just a little, but that is gone now too.

This had been functioning before I shut the supply valve. (Although the valve always has been a bit noisy, and slow - like 3 - 4 minutes to fill the tank).

I manually filled the tank back up hoping that might get the supply flowing, but no luck.

Do I have a bad valve? Air in line? Help?
