A toilet that keeps running after it’s flushed is easy to ignore. The sound fades into the background, and because the toilet still “works,” it doesn’t always feel urgent.
But a running toilet is rarely just an annoyance. It’s often a warning sign of hidden water waste, internal wear, or developing plumbing issues that can quietly cost homeowners money over time.
This article is part of the Fixtures & Everyday Use section of the Homeowner Education Series from 3rd Rock Plumbing, designed to help homeowners recognize small issues before they become larger problems.
Why Running Toilets Are So Common
Toilets rely on several internal components working together inside the tank. Over time, these parts wear down due to constant use, mineral buildup, or water pressure.
Common causes of a running toilet include:
Worn or misaligned flapper valves
Improper float height
Aging fill valves
Mineral buildup affecting seals
Because these parts are hidden inside the tank, problems can go unnoticed for long periods.
The Real Cost of a Running Toilet
Even a slow, steady flow of water can add up quickly.
A running toilet may:
Waste hundreds of gallons of water per day
Increase monthly water bills without obvious explanation
Put unnecessary strain on plumbing components
In many homes, running toilets are discovered only after homeowners notice higher utility bills — long after the issue began.
Why Running Toilets Shouldn’t Be Ignored
Beyond water waste, a running toilet can lead to additional problems, including:
Increased wear on internal toilet components
Potential leaks around supply connections
Stress on drain and vent systems
Masking of other plumbing issues
What starts as a simple internal repair can become more complicated when ignored for too long.
Simple Signs Your Toilet Is Running
Homeowners should watch (and listen) for:
Continuous water sounds after flushing
Water movement in the bowl when the toilet hasn’t been used
The tank refilling unexpectedly
A toilet that occasionally “turns itself on”
If you notice any of these signs, the toilet is not operating as intended.
DIY Awareness vs. Professional Evaluation
Some homeowners are comfortable replacing basic toilet components. Others prefer professional help — both approaches are valid.
However, 3rd Rock Plumbing recommends professional evaluation when:
The issue keeps returning
Multiple components appear worn
Water bills continue to rise
There are signs of leaking outside the tank
Trained and experienced plumbers like our staff can confirm whether the problem is isolated to the toilet or part of a larger plumbing concern. When a running toilet is more than just annoying, our plumbers can help you pinpoint the issue quickly to avoid bigger costs down the road.

What feels like a minor inconvenience is often one of the easiest opportunities for preventive care.
Frequently Asked Questions About Running Toilets
Why does my toilet keep running after I flush?
A running toilet is commonly caused by worn internal components such as a flapper, float, or fill valve. Mineral buildup and water pressure can also prevent parts from sealing properly.
Can a running toilet really increase my water bill?
Yes. A running toilet can waste hundreds of gallons of water each day, leading to noticeably higher water bills even though the toilet still appears to work normally.
Is it safe to ignore a running toilet?
No. Ignoring a running toilet can lead to ongoing water waste, increased wear on plumbing components, and the possibility of additional leaks or damage over time.
When should I call 3rd Rock Plumbing about a running toilet?
You should contact 3rd Rock Plumbing if your toilet continues running despite basic adjustments, if the problem keeps returning, or if you notice rising water bills or signs of leaking.
