Why Your Toilet Keeps Running & When to Call a Plumbing Service

How a Toilet Is Supposed to Work

After you flush, water leaves the tank and enters the bowl. The flapper then closes, and the fill valve refills the tank to the proper level. Once the water reaches that level, the fill valve shuts off.

If one of these parts doesn’t work properly, water may continue to run into the bowl or tank. That’s when you hear the toilet running long after the flush is complete.

Common Causes of a Running Toilet

A running toilet is often caused by one of several common issues:

• Worn or warped flapper
• Chain that is too tight or too loose
• Faulty fill valve
• Water level set too high
• Mineral buildup inside the tank
• Handle or flush mechanism sticking

Some of these issues are simple adjustments. Others require replacement parts or professional repair.

Why You Shouldn’t Ignore It

A running toilet can waste hundreds of gallons of water if it continues for days or weeks. Even if the sound is easy to tune out, increased water use can raise your monthly bill.

Ignoring the issue can also allow small parts to wear out further. A simple repair can become more frustrating if the toilet begins to flush poorly, refill slowly, or leak around the base.

When You Can Try a Simple Fix

If you’re comfortable checking inside the tank, you can look for obvious issues. Make sure the flapper is sealing properly, the chain has a little slack, and the handle isn’t sticking.

You can also check whether the water level is too high. If water is flowing into the overflow tube, the fill valve may need adjustment.

If the toilet still runs after basic checks, it is time to call a plumber.

When to Call a Plumber

You should call a plumber if the toilet keeps running after simple adjustments, if parts are visibly worn, or if the issue keeps coming back. You should also get professional help if you notice leaking around the base, weak flushing, frequent clogs, or water damage near the toilet.

Experienced plumbers can quickly identify the cause and make sure the repair is done correctly. They can also determine whether the toilet itself is failing or if the issue is connected to another part of the plumbing system.

A running toilet is easy to overlook, but it can waste water, increase costs, and create ongoing frustration.
