What is wrong with my supply line that causes the toilet tank to fill so slowly?
I've narrowed the problem down, and it's at the supply line to the fill valve. When I shut off the water supply and turn it back on, it fills the tank as it normally would -- but it's a one time fix. It won't work next time I flush, because if I flush it again, the flow is back to a drip. So I have to turn off the water again and turn it back on to get it to fill like normal. I have to shut off the water to the supply line every time if I want the tank to fill. How can I fix this permanently?

Well, you proved you have plenty of water coming from the suppy line. so it probably a faulty fill valve in the toilet tank. Or you have a loose rubber washer inside the shut of valve at wall.
To test this. flush your toilet and as it filling " so slowly " ( leaving the water turned on) unscrew the supply line to the toilet. if the water pressure remains " so slow " and low, it is the shut of valve. If the water comes gussing out it is the fill valve in your toilet.
Now you can narrow it down a little more. have fun.

I am pretty sure it is a problem with the flush valve, not the supply line. I'd replace the flush valve with a flow master. The pressure from the supply lone to the valve will not change flush to flush, so it has to be a valve problem. New valve is about $10.

my guess is calicum build-up in the water line, turn off your water, remove the live starting closet to the shut off valve and work your way to the toilet, look inside each line and clean out any debree, this should fix your problem... Good luck
