time and prepared for processing as a single unit or batch. Example: A cheque processing system in a bank.

When the rubber flapper is compromised, it allows water to run out of the drain causing the toilet to constantly refill. Replacing it is easy--replacements are available at most hardware stores or home centers. Be sure to take the old one with you to find a correctly matching replacement.
Run water from another location to see if the water level in the toilet bowl rises. If there is a tub or shower on the same floor and there is water backing up from one of these drains, then the problem is a main line problem. If you do not have a main line clog, use the toilet auger to clear the toilet.
