Why Does My Toilet Keep Running?

A toilet that won’t stop running can turn a quiet home into a source of constant noise, not to mention the unwelcome hike in your water bill. The culprit is often within the tank’s internal workings. Where flappers, floats, and chains play pivotal roles in controlling water flow.

Homeowners find these malfunctions both puzzling and frustrating. Fortunately, residential plumbing services specialize in such mysteries. Starting with an assessment for leaks might reveal if the problem lies concealed under the flapper’s seal.

Check Flapper for Leaks


A frequently running toilet often signals flapper issues. This rubber part is key to proper sealing; when damaged or aged, water leaks and causes unwarranted flushes. Handles on the chain that lift it can also misalign, disrupting closure and leading to constant leakage.

First, inspect your flapper for any signs of wear. Cracks or warps are clear indicators that a replacement is due. Remember, they last around four to five years typically.

Also assess if the chain has just enough slack. To let the seal happen smoothly after each flush.

Struggling with these fixes? Expert help from residential plumbing services might be what you need next.

Adjust the Float Mechanism


Adjusting the float mechanism is crucial if water keeps draining into the overflow tube. This causes that persistent running sound and may lead to bathroom damage. Two main types of floats manage tank water level: a buoyant ball or cylinder called a float cup.

For a ball-type, locate the adjustment screw on top of its valve. Turn it counterclockwise with a screwdriver. Just one-quarter turn lowers the floating arm and attached rubber ball.

The process for cylinders wrapped around valves. Is similar; they slide along their shafts to set levels.

Loosen their screws slightly in quarter-turn increments until you achieve about 1 inch below your overflow tube’s edge after refilling. Make sure nothing’s tangled up inside like chains obstructing movement, and check any fill tubes stay above full-tank water lines to avoid intermittent runs. 

Inspect Chain Length and Tension


A toilet chain that’s too long is trouble. It can sneak under the flapper, blocking a tight seal and causing constant running. This not only spikes your water bill but also wastes precious resources.

Redhead Rooter suggests checking if handle jiggles stop the flow; it’s likely an extended chain issue then. Shortening this part takes minutes yet saves gallons.
