My toilet flushes just fine, but after the tank drains it doesn't fill back up. I have to manually push down the float cup to get it to refil the tank. I have no ideas how to fix this.

Can anyone help?

Thanks,

Tim

I think you must have a "Fluidmaster" valve and you can get parts at most hardware stores. The parts kit that you buy will have instructions on how to replace them.

Let me know if this helps.
