: I flushed my toilet today and for the first time it does not fill up (no water fills the tank). I will head to Home Depot in the A.M. to try to fix. Please help a father of 4 (always on the toilet) who does not know too much about plumbing. What should I buy? Fluid Master 400A and follow directions BE CAREFUL. Do not forget to shut the water supply. Sylvan
