Lowering the water level in a toilet is a simple task that can save you money on your water bill. A flapper valve that is not sealing properly or a fill valve that is out of adjustment can waste gallons of water per day.
In addition to saving money, lowering the water level in your toilet can also help to prevent clogs. A higher water level can create more force when the toilet is flushed, which can dislodge clogs. However, a lower water level can reduce the amount of force, making it less likely for clogs to occur.
