After the toilet is flushed and the water in the tank drops the floats drops but even with additional downward pressure water doesn't fill up the tank in earnest
Ok...first turn off the water supply at the shuttoff valve under the tank(presuming you have one if not shut the water off some how) disconnect the supply line from the flote valve and hold it into a 5 gal bucket while you turn the water back on slowly. if you are getting good pressure from the supply line then the flote valve is bad or has been obstructed by foreign matter.
