Whenever I flush the toilet, I have to manually press down on the valve for it to fill up with water. Then once it's full, it keeps running and I have to jiggle the valve in order to stop it. It started happening when the water was accidentally shut off and the toilet didn't refill, so I was playing around with the fill valve thinking it was broken, but I ended up doing something to it. I would just like to know how I should attempt fixing it. Thanks.
I have a Moen M5350 fill valve, which I attached for reference.
