The mechanism in my toilet tank is not working right. I flush it and a few minutes later I hear a sound like rushing water. It keeps doing this over and over again. It keeps me awake. I must have done something bad to make this happen. I don't know whether to stay in bed and pray that God will fix the toilet or get up every time this happens, jiggle the handle and hope that if I do this enough times something will catch and eventually the sound of rushing water will stop.
