Why does my toilet keep running after I flush?

A constantly running toilet is almost always caused by a worn flapper that no longer seats against the flush valve, allowing tank water to slowly drain into the bowl. A failing fill valve that can't maintain proper tank water level is the second most common cause. Both repairs take under 30 minutes and cost under $150.

Should I repair my toilet or replace it?

Repair if the toilet is less than 15 years old and only one component has failed - flapper, fill valve, flush handle, or wax ring. Replace if the toilet is cracked at the base or tank, if it requires repeated repairs, or if it is an older 3.5-gallon-per-flush model. A new 1.28-GPF toilet saves 20-30 gallons per day compared to older units.

How do I know if my toilet wax ring is failing?

Water staining, soft flooring, or a springy feeling around the base of the toilet indicates the wax ring seal has failed. You may also notice a sewer odor near the toilet even when the bowl is clean. A failed wax ring leaks water and sewer gas into the subfloor every time the toilet is flushed - it should be replaced promptly.
