What Causes Toilet Running Constantly
A constantly running toilet wastes 200+ gallons of water per day. The most common causes are a worn flapper valve, a faulty fill valve, an improperly adjusted float, or a leaking flush valve seal. These components wear out every 3-7 years with normal use.
Boise-specific factor: Boise's hard water deposits mineral scale on flappers and fill valves, accelerating wear. Many Boise homeowners don't notice a running toilet until they receive an unexpectedly high water bill from United Water Idaho.
Signs You Have Toilet Running Constantly
Watch for these warning signs in your home:
- ✓ Toilet runs constantly or intermittently cycles on and off
- ✓ You hear water running in the bathroom when no one is using it
- ✓ Water bill suddenly increases
- ✓ You have to jiggle the handle to stop the running
Can You Fix This Yourself?
Remove the tank lid and check the flapper — if it's warped, cracked, or has mineral buildup, replace it ($5-$10 at any hardware store). Check the fill valve float and adjust if the water level is above the overflow tube. Most running toilet fixes are DIY-friendly.
If the problem persists or you're unsure, call a licensed plumber. Attempting complex repairs without proper tools can cause further damage and void warranties.
