A running toilet is one of the most common plumbing issues that homeowners face. The mechanisms of a toilet are delicate, and a single faulty piece can cause this issue. While it’s always important to call a professional for toilet repair, it’s also helpful to understand which factors could be causing the toilet to run. 

Common Causes of a Running Toilet

The Flapper Chain is the Wrong Size

If you recently bought a new toilet or replaced the flapper chain yourself, the part might not be the proper size. A short chain doesn’t allow the flapper to seal shut, so the water runs after flushing. When the flapper chain is too long, the flapper doesn’t open and shut properly, and the chain can block the flapper from sealing. A professional can take measurements of your toilet and ensure that the chain is the proper length.

The Toilet Handle Is Damaged

When you press the toilet handle, this triggers the water to run and then shut off. However, an old or damaged handle can get stuck in the downward position and cause the toilet to keep running. This can be due to physical damage or corrosion. Instead of undertaking extensive toilet repairs, a professional might just have to replace the handle to keep the water running as it should.

You Need a New Flapper

The toilet stops running when the flapper seals shut. However, this response won’t happen if the flapper is unable to seal. An old or cracked flapper might be letting water through, which results in constant running. While completing toilet repairs, a professional plumber will ensure that your fixture has a properly sized flapper.
