Before Calling a Plumber…
A few safe, simple checks may save you a service call:
- ✓Remove the tank lid and check whether the flapper is seating properly
- ✓Check whether the chain is tangled or too tight/loose
- ✓Check whether water is running into the overflow tube
- ✓Add food coloring to the tank — if color appears in the bowl after 15 minutes, the flapper is leaking
Many Knoxville homes have older toilets that use 3.5 gallons per flush or more. Replacing with a modern 1.28-gpf toilet can reduce water bills. In older homes, the closet flange may be cast iron and corroded, requiring replacement during a toilet swap. Wax ring failure is common in homes where the toilet has been in place for decades.
