IMPERIAL GV0624-C DUCT ANGLE BOOT 3-1/4X10X6IN

Good day! I'm sorry to hear that your Toto TSU16A fill valve assembly isn't working well. In order to stop it from running, you need to adjust the height of the fill valve assembly. Simply twist the valve assembly and slide down about half of an inch or so. Then, twist it back for it to be secured in place. If you got the type that has a ball float, bend the arm that connects to the float down. If you need further assistance, it would be best to contact the manufacturer at 1-888-295-8134.
