5 Reasons Why Your Toilet Keeps Running

A constantly running toilet isn’t just an irritation—it’s also a waste of water and can significantly increase your water bill. At Parks Plumbing, we often address this common household issue and help our clients understand the underlying causes. By recognizing why your toilet keeps running, you can take the necessary steps towards an effective solution. Here, we discuss the top five reasons why your toilet may not be functioning correctly and how to address them.

1. Faulty Flapper Valve

What It Is: The flapper valve is responsible for releasing water from the tank into the bowl when you flush and sealing the water intake hole afterward so the tank can refill.

Why It Fails: Over time, the flapper can wear out or become warped, creating a poor seal that lets water drip continuously into the bowl.

Solution: Check the flapper by turning off the water supply and marking the water level in the tank. If the water level drops, replace the flapper. Parks Plumbing offers toilet repair services to help with such issues.

2. Problems with the Fill Valve

What It Is: The fill valve controls the water flow into the toilet tank after flushing.

Why It Fails: A faulty fill valve can prevent the tank from filling properly, causing a constant flow of water to try and fill the tank.

Solution: Listen for a hissing sound, which is a common sign of a leaking fill valve. Replacement is typically the best option, and our experienced technicians can handle this for you efficiently.

3. Improper Float Ball Adjustment

What It Is: The float ball sits on the surface of the water within the tank and stops the fill valve once the water reaches the appropriate level.

Why It Fails: If not properly adjusted, the float ball might not rise enough to shut off the water, leading to overfilling and water spilling into the overflow tube.

Solution: Adjust the float ball so it sits lower in the water, stopping the water at an appropriate level. If adjustments don’t work, it might need replacing.

4. Malfunctioning Chain or Lever

What It Is: The chain or lever connects the flush handle to the flapper valve.

Why It Fails: If the chain is too tight, it can prevent the flapper from sealing properly after a flush, allowing water to leak continuously.

Solution: Adjust the chain length so there’s just a little slack when the flapper is closed, ensuring it can seal properly. If the handle must be jiggled to stop the water, this could be your issue.

5. Leaking Tank

What It Is: Cracks in the toilet tank can cause water to leak, sometimes silently, into the toilet bowl.

Why It Happens: Age or impact can cause small cracks to develop in the porcelain.

Solution: Cracks can sometimes be difficult to spot. Look for wet areas on and around the toilet. Significant cracks typically require the toilet tank to be replaced. Our team can assess and provide the necessary replacements.
