Why Your Toilet Runs Randomly For a Few Seconds
When your toilet runs randomly, something has gone wrong with the flushing mechanism. Most commonly, something is preventing the flapper from closing completely. Therefore, it is always letting a small amount of water out of the bowl. Then, once the toilet tank is empty, the fill valve is triggered, and it refills the tank. That’s what you hear when your toilet runs for a few seconds—the tank refilling.
So, the question is, what is keeping the flapper from fully closing? Sometimes it’s the chain, it could be too short, or it could be getting caught on something. Or, the handle itself could be stuck too high, preventing the chain from fully lowering. Calcium and other mineral build-ups in the tank could prevent the flapper from making a proper seal. Or, the flapper could be broken, chipped, or stuck.
That’s just the root causes of one potential toilet problem. If the issue isn’t with the flapper, then a whole host of other problems might be causing your toilet to run. The floater or the fill valve may not be working properly, for one reason or another. At some point it’s better to replace the toilet entirely.
In the end, you’ll need a plumber to find out the reason your toilet is running randomly for a few seconds, and to fix it.
Why Fix a Running Toilet?
A toilet with a phantom flush may not seem like a big deal. After all, you just hear it flush once or twice per day—so what’s the harm?
First, the toilet is likely flushing much more often per day; you just aren’t nearby to hear it. These extra flushes are wasting water. In fact, they could even double your water bill if the phantom flush is happening often enough, or if your toilet has a very large tank. To keep your water costs low, it is best to get this problem fixed right away. Contact our toilet repair experts in Castro Valley if you’re looking for dependable, local help.
