Why does my toilet keep running?
Nearly always the flapper or the fill valve. A running toilet can waste a surprising amount of water, and it is one of the cheaper repairs in the house, so it is worth doing rather than living with.

Toilet Repair & Replacement
Repairing and replacing toilets — running fills, weak flushes, rocking bases, and leaks at the floor.
When people call us about toilet repair & replacement
- A toilet that keeps running after the flush
- One that needs the handle held down, or flushed twice
- A base that rocks or a floor that feels soft around it
- Water appearing at the base after a flush
- A tank that refills on its own between uses
How we handle it
- Fix the mechanism where the fault is the fill or flush valve, which it usually is.
- Pull and reset where the wax seal has failed rather than patching around it.
- Check the flange and subfloor before resetting, because a rocking toilet damages both.
- Replace when the fixture itself is cracked or the repairs stop being economic.
What we check before quoting
- Fill valve, flapper, and flush valve operation
- Flange height and condition
- Subfloor condition around the base
- Supply line and stop valve
Toilet Repair & Replacement FAQs
My toilet rocks slightly. Does that matter?
Yes. Movement breaks the wax seal, and once that goes, water reaches the subfloor every time it is flushed. The rocking itself is usually a flange or shim issue and is straightforward to correct before it causes damage.
Is it worth repairing an old toilet?
If the fixture is sound, mechanism repairs are usually the better value. If it is cracked, or if an older high-volume unit is being replaced anyway during a bathroom update, replacement makes more sense.
