Review on 🚽 Fluidmaster 242 Toilet Fill Valve Seal Replacement Part - Compatible with 400A Fill Valve, Black by John Invert

I'm not a plumber. novice master. The toilet filled very slowly over several months. I adjusted the fill valve by simply pushing it down and counterclockwise (no water). So if a piece came loose, I really cleaned it first and put it back in place. I learned this part from a simple YouTube search. It worked, but only for half a day, and the water slowly began to rise again. On the next lap I turned it upside down and the water filled up very quickly but didn't stop filling. It told me that would be the part if it felt really fast and didn't stop. I just have to replace this part because if it turns upside down quickly, it's obvious that the head is wrong and I can't shut off the water properly, but the problem wasn't in the valve. So instead of buying a whole new inflation valve I just bought this part, installed it and it's been working perfectly ever since.
