How To Fix A Toilet That Keeps Running Water

A running toilet is more than just an annoyance; it can waste gallons of water and increase your water bills. Fortunately, fixing a running toilet is often a simple task that can be completed in a few minutes with basic tools. In this comprehensive guide, we’ll walk you through the most common causes of a running toilet and provide step-by-step instructions on how to fix them.

Common Causes of a Running Toilet

• Faulty Flapper Valve: The flapper valve is a rubber seal that sits at the bottom of the toilet tank and prevents water from flowing into the bowl after flushing. If the flapper valve is worn or damaged, it can cause water to leak continuously into the bowl.
• Leaking Fill Valve: The fill valve is responsible for filling the toilet tank with water after flushing. If the fill valve is faulty, it can overfill the tank, causing water to run into the overflow tube and down the drain.
• Worn Out Toilet Seat: The toilet seat and its components can also cause a running toilet. A loose or misaligned toilet seat can put pressure on the flapper valve, causing it to leak.
• Clogged Flush Valve: The flush valve opens and closes the hole at the bottom of the toilet tank to release water into the bowl. If the flush valve is clogged with debris, it can prevent the toilet from flushing properly, resulting in a running toilet.
• Cracked or Damaged Toilet Tank: A cracked or damaged toilet tank can allow water to leak out of the tank and into the bowl, causing a running toilet.
• Loose or Damaged Supply Line: The supply line connects the toilet to the water supply. If the supply line is loose or damaged, it can leak water into the toilet tank, causing a running toilet.
• High Water Level in the Tank: The water level in the toilet tank should be set to a specific level to ensure proper flushing. If the water level is too high, it can overflow into the overflow tube and cause a running toilet.

Step-by-Step Instructions on How to Fix a Running Toilet

1. Turn Off the Water Supply: Locate the water supply valve behind the toilet and turn it off. This will stop the flow of water into the toilet.

2. Flush the Toilet: Flush the toilet to empty the tank and bowl.

3. Remove the Toilet Lid: Lift the toilet lid off the tank.

4. Inspect the Flapper Valve: Check the flapper valve for damage or wear. If the flapper valve is damaged or worn, replace it with a new one.

5. Inspect the Fill Valve: Check the fill valve for any signs of leaks. If the fill valve is leaking, replace it with a new one.

6. Check the Toilet Seat: Make sure the toilet seat is properly aligned and tightened. If the toilet seat is loose or misaligned, tighten it or replace it.

7. Unclog the Flush Valve: Remove the flush valve cap and check for any debris clogging the flush valve. If the flush valve is clogged, clean it out with a wire or pipe cleaner.

8. Inspect the Toilet Tank: Check the toilet tank for any cracks or damage. If the toilet tank is cracked or damaged, it will need to be replaced.

9. Check the Supply Line: Inspect the supply line for any leaks or damage. If the supply line is leaking or damaged, replace it with a new one.

10. Adjust the Water Level in the Tank: The water level in the tank should be set to about 1 inch below the top of the overflow tube. Adjust the water level by turning the adjustment screw on the fill valve.

11. Turn On the Water Supply: Turn the water supply valve back on and check for any leaks. If there are no leaks, the running toilet should be fixed.
