The right part, once
A toilet running through the night, shifting when you sit down, or leaving a puddle at the base after each flush is usually one worn part away from a real fix, and identifying that part comes before anything gets touched.
Why won’t my toilet stop running after a flush?
Two small parts inside the tank are almost always responsible. One is the flapper, a rubber disc that seats over the drain and is meant to hold water in the tank between flushes. The other is the fill mechanism that senses the water level and stops the refill once the tank is full. When the flapper sits crooked or has gone stiff with age, it lets water slip past continuously, so the fill mechanism keeps working to replace what’s escaping, and that constant back-and-forth is the sound you can’t get to stop.
Neither part costs much, and either one is a quick swap once identified. What’s worth asking, though, is why it failed early in the first place: Davie’s water carries enough dissolved mineral content that rubber components here tend to give out sooner than the same parts would somewhere with softer water.
WHAT WE FIX
A worn flapper, a worn fill mechanism, or both working against each other. Whether it never stops or just cycles every few minutes, the underlying cause is usually the same pair of parts.
Points to a failing wax seal between the toilet base and the floor drain, a fix that means lifting the toilet, not just running a bead of caulk around the outside.
A supply valve that isn’t fully open, a rim clogged with mineral scale, or a flapper dropping shut too soon and cutting the flush off early.
Puts ongoing stress on that wax seal, and given enough time, usually ends in a leak at the base once the seal finally fails.
Older low-flow models sometimes can’t clear the bowl in one pass. If a plunger doesn’t fix a recurring pattern, the issue may sit further down the line rather than in the toilet.

DAVIE, SPECIFICALLY
Central Davie’s housing stock largely dates to a single stretch, roughly the 1970s into the 1990s, so the internal toilet parts across a street, flappers, fill assemblies, flush handles, tend to reach the end of their life within the same few years. It isn’t unusual to replace the same part in three or four houses on one block in a single season.
Homes west of University Drive are often tied to a septic tank and drain field rather than the municipal system, and that setup reacts far more harshly to what gets flushed, wipes, heavy paper, harsh cleaners, than a city sewer connection ever would.
A toilet on well water depends on an electric pump to refill the tank after every flush. When a hurricane knocks out power on the well-and-septic side of town, that toilet can sit empty between flushes even though nothing inside it is actually broken.
Before you call
Usually, yes, it’s about as approachable as home plumbing repairs get. If a fresh flapper doesn’t quiet things down within a day, look to the fill mechanism or the flush valve seat instead.
More than most people guess, since it’s constant rather than occasional. A toilet running non-stop for a full day can burn through a surprising volume, sound or no sound.
Water appearing at the base right after a flush, combined with a toilet that shifts slightly when you sit, points squarely at the seal. A caulk bead can mask it visually while the subfloor keeps soaking it up underneath.
Just the part, almost every time. A full replacement only makes sense when the bowl or tank is physically cracked, seriously outdated, or you’ve decided you want an upgrade anyway.
It changes what we’d flag for you going forward more than the repair itself, since a drain field responds to flushed material very differently than a sewer line does.
