There was a water main break somewhere in our town. We have low water pressure, but nonetheless we have water. Including the upstairs bathroom; sink and shower, but not in the toilet. A friend said it was because of the low pressure. Please tell me that is the case or otherwise I have a flushmaster water supply in the tank... could it be a problem with that?

Thanks for any help you can give.
