Having to flush your toilet twice to clear waste completely is usually caused by insufficient water volume in the tank, a partially obstructed trapway, or mineral scale buildup blocking the rim feed holes. If the water level inside the tank sits too low, the flush lacks the necessary gravitational force and siphon suction to pull waste down the drain pipe effectively. Adjusting the fill valve float upward or cleaning scale from the rim jets will often restore single-flush performance. Verification: Test a complete flush cycle after adjusting the water level to ensure powerful waste clearance.
