I have a push button toilet and it fills up very slowly.. what do I need to do?

Which ball cock. Is yours? Back to you, Tom

It may not be either of those, Tom... not if it is a pressure-assist toilet.

If this is a pressure-assist toilet Peanut would need to provide us with the exact name brand and model number of the toilet (usually under the tank lid) if you want any information from us.

Otherwise, if this is not a pressure-assist toilet, then you probably have the fill valve on the left in Tom's pictures. This fill valve is easily disassembled and cleaned which is probably what will need to be done.

Let us know more here, OK?
