A toilet that keeps running can waste water and may point to a problem with the tank or flush mechanism. Use the guidance below to make a safe first observation, then go to the Toilet Repair service page if you need professional help.

What a running toilet may mean

Common possibilities include a tank component that is not closing properly, a flush mechanism that is not resetting, or water continuing to enter the bowl. The sound alone cannot confirm the cause.

Safe observations you can make

Listen for whether water runs continuously or only after a flush. From outside the toilet tank, note whether the sound changes when the normal flush control is used. Check for visible water around the toilet base or nearby flooring. Do not dismantle the tank or force components if you are unsure what you are seeing.

When to contact a plumber

Contact a plumber if the toilet continues running after normal controls are used, water is visible around the base, the problem returns, or you cannot identify the source safely. Seek prompt help if water is spreading onto flooring or causing visible damage. Avoid unsafe repair attempts and have a qualified professional inspect the fixture.

Choose the relevant service

Toilet Repair is the most relevant service for a toilet that will not stop running. When contacting a company, describe how long the problem has been happening, whether it runs constantly or after flushing, and whether you see water outside the bowl or tank. Confirm that the company serves your Pasadena address and handles toilet repair.
