My 10 year old Toto toilet was making crying noises and kept refilling about every 15 minutes. I replaced the fill valve. The crying stopped but the leaking didn’t. I put food coloring in the tank and it leaked into the bowl, but not down the sides. It leaked through the little hole toward the front of the toilet into the bowl. There is no water around the floor. So, it doesn’t seem like it’s a problem with the flapper. How else can the water get out of the tank?
