What is the most common cause of a running toilet leak?

A running toilet leak is often caused by the flapper not sealing or a fill valve that doesn’t shut off. The chain or handle linkage can also keep the flapper from closing. Our techs inspect these parts first and use professional-grade tools to fix the issue. Same-day appointments are available in areas like Bastrop and Austin.

Quick checks:

• Make sure the chain isn’t too tight or too loose.
• Inspect the flapper for wear or debris and reseat it.
• Listen for constant refill at the fill valve.
