A toilet that keeps running is the most common call our Michigan plumbers get — and one of the most expensive problems to ignore. A silently running toilet can waste 200 gallons or more per day, which shows up fast on a water bill. The good news: most running toilets have one of six causes, and all of them are fixable in a single visit.
Every time your toilet refills on its own (a “phantom flush”) or hisses continuously, treated water is going straight down the drain. In cities with metered water like Detroit, Grand Rapids and Ann Arbor, that can add $50–$100 a month to the bill. It also keeps the fill valve working constantly, which wears it out sooner.
The rubber flapper at the bottom of the tank seals the flush valve. Over time it warps, gets coated in minerals (very common with Michigan's hard water) or simply loses its seal. Water trickles into the bowl, the float drops and the tank refills every few minutes. A flapper replacement is quick, but matching the right size and style matters — a universal flapper that doesn't quite fit will leak again in weeks.
If you hear a constant hiss, the fill valve isn't closing. Debris in the valve, a worn diaphragm or a cracked valve body all cause this. Our plumbers replace it with a quality adjustable fill valve and set the water level correctly.
When the float is adjusted too high, water rises above the overflow tube and drains continuously. Lowering the float is a two-minute fix — but if the float is waterlogged or the arm is bent, it needs replacing.
A flush chain that's too short holds the flapper slightly open; one that's too long gets trapped under the flapper. Both let water leak into the bowl.
Older toilets develop hairline cracks in the overflow tube or a pitted flush valve seat. No flapper will seal against a damaged seat. This requires replacing the flush valve assembly — a bigger job that still fits in one visit for our toilet repair team.
If the toilet is decades old, uses 3.5+ gallons per flush, has a cracked tank or needs repairs every year, toilet replacement with a modern 1.28-gpf model often pays for itself in water savings.
If you've replaced the flapper and it still runs, if there's water around the base of the toilet, or if the toilet also gurgles or flushes weakly, call a plumber. Those symptoms can point to a failing wax ring or a drain line issue. Elite Plumbing and Heating MI provides same-day toilet repair across Michigan — call (888) 480-9811.
Anywhere from 20 to 200+ gallons a day depending on the leak. Even a slow flapper leak adds up to thousands of gallons a month.
Often yes — a flapper or float adjustment is simple. If that doesn't solve it, the flush valve or fill valve likely needs professional replacement.
Put a few drops of food coloring in the tank and wait 15 minutes without flushing. Color in the bowl means the flapper is leaking.
