I flush and then the tank fills up but the water keeps running into the white perpendicular tube from the little black tube that is secured on the lip of the white tube with a metal clip. The only way to stop the flow is to shut the water off. I have wiggled the plastic screw on top of the blue unit to the left with a screwdriver to no avail. Any ideas will be appreciated (I am new at this DIY thing, but I need to get up to speed because I cannot afford plumbers. Honest). Many thanks.
