Why Is Your Toilet Not Flushing?
Several plumbing problems can prevent a toilet from flushing properly. Some are simple fixes, while others require professional repair.Faulty Flapper Valve
The rubber flapper inside the tank controls water flow into the bowl. When it becomes worn, cracked, or warped, the toilet may not release enough water for a complete flush.Low Water Level
If the tank isn't filling to the correct level, there won't be enough pressure to create a strong flush. This can result from:- Malfunctioning fill valve
- Improper float adjustment
- Mineral buildup from hard water
Clogged Trap or Drain Line
One of the most common causes is a blockage inside the toilet trap or deeper in the drain system. Items such as excessive toilet paper, hygiene products, children's toys, or foreign objects can restrict water flow.Signs You Need Professional Toilet Repair

Water Rising Before Draining
