Slow tank fill
I am trying to determine the cause of slow tank fill up on one of my toilets. I have 3 1/2 baths in my home, and the only one I seem to have the problem with is in the powder room on the main floor. I replumbed the inside of the tanks in all my toilets several years ago to remove the ball floats and replace them with the float that goes up and down on the post. For some reason (???) this toilet takes forever to refill the tank after it has been flushed. I can't find any obvious problem. I would appreciate any/all recommendations to resolve this situation. Thanks!
