We had a mystery problem in our house since last summer, where the toilets would randomly make noise..mostly in the middle of the night when we were trying to sleep :( Finally got fed up and called to have it looked at, and they came out same day and figured out the issue. $40 in parts and $75 in labor later I say happily state that we arent being woken up in the middle of the night with running toilet noises..hallelujah.
