Encountering a running toilet is a common and bothersome plumbing issue that homeowners frequently face, causing frustration and unnecessary water wastage. The constant flow of water increases water bills and contributes to water wastage. While some toilet problems can be fixed with basic DIY solutions, persistent issues may require the expertise of a professional plumbing company. In this article, we will explore common reasons behind a running toilet, DIY troubleshooting steps, and when it’s time to enlist the services of a reliable plumbing company.

Common Causes of a Running Toilet

Flawed Flapper Valve

The flapper valve, an essential component inside the toilet tank, fulfills a vital function. When it fails to create a proper seal, water incessantly seeps into the bowl, continuously running the toilet.

DIY Advice

Examine the flapper for indications of wear and tear. If it is damaged, substitute it with a new one.

Float Issues

A malfunctioning float can lead to an imbalanced water level in the tank, causing the toilet to run excessively.


Adjust the float to the correct water level. If the problem persists, the float may need replacement.

Flawed Fill Valve

The fill valve regulates the water flow into the tank, and if it experiences a malfunction, it can lead to a continuous inflow of water into the tank.

DIY Advice

Clean the fill valve and inspect for any observable issues. If challenges persist, it might be advisable to consider replacing the fill valve.

Leakage in Flush Valve Seal

The flush valve seal prevents water leakage into the bowl following a flush.


DIY Suggestion

Examine the flush valve seal for any signs of damage and replace it if needed.

With time, minerals can gather in the toilet tank, impacting the operation of its various components. Skilled plumbers have the expertise and tools to remove mineral deposits proficiently, reinstating the toilet’s peak efficiency.
