Why is my toilet constantly running?

A constantly running toilet is not just an annoyance—it can waste hundreds of gallons of water per day, increasing your utility bills. The most common cause is a faulty flapper valve, which controls water flow from the tank to the bowl.

When the flapper doesn't seal properly, water leaks into the bowl continuously. Replacing the flapper is usually a simple and inexpensive fix.

Another potential culprit is the float, which regulates the water level in the tank. If the float is set too high, the tank will overfill, and excess water will drain into the overflow tube. Adjusting the float to the correct height can resolve this issue.

Sediment buildup or a malfunctioning fill valve can also cause running. Cleaning or replacing the valve may be necessary if adjustments don’t help.

If you've tried DIY fixes and the toilet still runs, it may be time to call a plumber. At Blue Mountain Plumbing, we provide toilet repair for customers all across the region.

Persistent running could indicate deeper issues within your plumbing system.
