This sound can happen intermittently and occur every few minutes or every few hours. Such a refill sound is usually alerting you that your toilet is losing water, either internally (if there’s no water on the floor or exterior of toilet) or externally leaking if you see water outside the toilet.
Why does my toilet keep refill periodically?
You may periodically hear your toilet begin to spontaneously refill, as though someone had flushed it. A toilet that cuts on and off by itself, or runs intermittently, has a problem that plumbers call a “phantom flush.” The cause is a very slow leak from the tank into the bowl.
How do you fix a toilet that fills randomly?
Solution 1: Replace the Flapper
Use a sponge to clean up any leftover water and then unhook the flapper and replace it with a new one. Turn the water supply back on and test. If the toilet randomly runs or the tank starts filling by itself, it’s a sign that the flap is failing.
How do I stop my toilet from running intermittently?
If the toilet keeps running or runs intermittently, you’re not getting a good seal. Try a different flapper if the toilet won’t stop running. If you just can’t find a flapper that seals, consider replacing the entire toilet overflow tube/flapper. On most toilets (two-piece), this means removing the tank.
Why does my toilet keep filling up every few minutes?
In the vast majority of cases, the problem is with the flapper, which is the rubber seal between the tank and the bowl. When it’s worn, or the chain is too short, water seeps into the bowl, and the fill valve cycles on as soon as the float falls below the cutoff level.
