A worn flapper, a clogged fill valve or a float that is set too high are the most common causes of a running toilet. Even a small trickle can waste water, raising your utility bill. Understand why your toilet keeps running, how to troubleshoot it and when to call professional plumbers.
Reasons Your Toilet Keeps Running
These are the main causes of a running toilet:
Worn-out toilet flapper: A rubber flapper lifts during a flush to release tank water into the bowl, then closes over the flush valve opening. An old or damaged flapper can fail to form a tight seal, causing water to keep leaking into the bowl.
Broken fill valve: The fill valve controls the flow of water into your toilet. If the valve is worn, clogged with sediment or failing to shut off, water can keep entering the tank and draining through the overflow tube.
Incorrect float height: Your toilet's float notifies the fill valve once the tank is full after flushing. If you set the water level too high, the water inside the tank spills over the overflow tube.
Flush chain problems: A too-short chain can hold the flapper open, while a too-long chain can tangle or get caught under the flapper.
Overflow tube issue: A cracked or damaged overflow tube can let tank water leak into the bowl, causing the tank level to drop and the fill valve to keep refilling.
Consequences of Ignoring a Running Toilet
Running toilets waste around 200 gallons of water each day. That waste leads to higher water bills for you and depletes precious natural resources. Continuous water flow can also speed up wear on your plumbing components. Over time, you may need more frequent repairs or part replacements.
Troubleshooting a Running Toilet
A simple tank inspection can help catch small issues before they become bigger repairs:
Remove the tank lid: Lift the porcelain lid off the top of the tank, placing it on a towel on the floor.
Check the water level: Examine the overflow tube in the middle of the tank. If water spills into the tube, it means the water level is too high.
Inspect the flapper: The flapper sits at the bottom of the tank. Water leaking past the rubber seal points to a worn or damaged flapper that needs replacement.
Assess the chain and fill valve: Look for a tight chain that keeps the flapper open, then check the fill valve for cracks or visible damage.
If you spot any problems, avoid trying to solve these yourself. It is better to schedule an inspection with licensed plumbers who can give you a clear diagnosis.
When to Call a Professional Plumber for a Leaky Toilet
You should contact a reliable local plumbing company when:
Water continues to run after basic troubleshooting.
You see water pooling on the floor around the base or dripping from the tank.
The toilet tank or bowl has visible cracks.
A stuck water shut-off valve prevents you from turning off the water.
Your toilet makes gurgling or bubbling sounds.
