That Sound Is Costing You Money
If you can hear your toilet running long after the last flush — or if it cycles on and off by itself — you are literally listening to money go down the drain. A running toilet can waste hundreds of gallons of water per day. In Manatee County, where you pay for both water and sewer on the same bill, that is a significant cost. The good news is that this is one of the most common and most fixable plumbing problems there is.
The Most Likely Culprit: The Flapper
About 80 percent of the time, a running toilet comes down to a worn-out flapper — the rubber seal at the bottom of the tank that lifts when you flush and drops back down to seal the tank. Over time, flappers warp, crack, or develop mineral buildup from our hard Bradenton water. When the flapper does not seal properly, water slowly leaks from the tank into the bowl, and the fill valve kicks on to top off the tank. That is the running sound you hear.
Replacing a flapper is a five-dollar, ten-minute fix. Turn off the water supply valve behind the toilet, flush to empty the tank, and swap the old flapper for a new one. They are available at any hardware store. Just bring the old one with you to match the size.

Other Common Causes
If a new flapper does not solve the problem, the fill valve may be the issue. The fill valve controls the water level in the tank, and when it malfunctions, it can let water rise too high and spill into the overflow tube. You can check this by looking inside the tank — the water level should be about an inch below the top of the overflow tube. If water is flowing into the overflow, the fill valve needs adjusting or replacing.
Less commonly, the flush valve seat — the surface the flapper sits on — can develop mineral deposits or corrosion that prevent a proper seal. You can sometimes fix this with fine sandpaper or emery cloth. If the seat is cracked, though, you are looking at a more involved repair or a toilet replacement.
When to Call a Plumber
If you have replaced the flapper and checked the fill valve and the toilet still runs, it is time to call in a professional. There may be a crack in the tank, a problem with the flush valve assembly, or an issue with the water supply line. These are not difficult repairs for a licensed plumber, but they are beyond most DIY comfort zones.
