Toilet overflowing onto the bathroom floor: stop it in under a minute
Water on the floor spreads fast. These steps work on almost every toilet, and then you can call (855) 575-2890 without a flood in progress.
- 1
Lift the tank lid and raise the float
Hold the float arm or the float cup up. That stops more water entering the tank.
- 2
Close the supply valve
Turn the oval handle on the wall or floor behind the toilet clockwise until it stops.
- 3
Do not flush again
A second flush sends more water into a bowl that is already full.
- 4
Soak up the water
Towels first, then a wet vacuum. Open a window if the water is dirty.
- 5
Call the 24/7 line
If the valve will not turn or the bowl keeps rising, the clog may be past the toilet. Say so to the dispatcher.
What the problem usually means
| What you see | Likely cause | Typical fix and range |
|---|---|---|
| Toilet runs after flushing | Worn flapper or fill valve | Replace parts, $120 to $300 with a plumber |
| Water around the base | Failed wax ring or loose closet bolts | Reset the toilet with a new ring, $150 to $400 |
| Bowl rises, then drains slowly | Clog in the trap or branch drain | Auger the toilet, $100 to $400 |
| Sweating or dripping tank | Condensation, or a cracked tank | Check for cracks, replace if cracked |
| Weak flush | Clogged rim jets or low tank water | Clean jets and reset the water level |
| Rocking toilet | Loose flange or bolts | Re-seat and re-shim, $150 to $400 |
These are typical U.S. ranges. A call gives the real number for your toilet.
Chloramine in Greenville Water and the rubber inside your tank
Mauldin is served by Greenville Water, which draws from Table Rock Reservoir, North Saluda Reservoir and Lake Keowee. Its 2025 water quality report lists chloramine, chlorine combined with ammonia, as the disinfectant. Chloramine can wear rubber flappers and seals faster than plain chlorine, as plumbers see across many utilities.
What to do with that: if your flapper is soft, swollen or sticky after a few years, replace it instead of adjusting the chain. A $10 part is cheaper than the water a leaking flapper wastes, and it is the cause of many running toilets.

Repair it or replace the toilet
Parts are cheap and a toilet should last many years, so repair wins when the china is sound. Replace the toilet if the bowl or tank is cracked, if it rocks on a damaged flange, or if it needs a repair every few months.
Mauldin has buildings from every era, from the 1937 school that is now the Cultural Center to the Sports Center opened in 2007. Toilet age works the same way. Lift the tank lid and look for the date stamp. A toilet made before 1994 may use 3.5 gallons per flush, and a modern 1.28 gallon model can cut the water used by more than half.
Cracked tank or a toilet that will not stop flooding
Some toilet problems cannot wait until morning. Call the 24/7 line right away in these cases.
Sewage, not clean water
Dark or foul water coming up means a drain problem. Sewage backups need a plumber, not a new flapper.
Water through the ceiling below
A leak at the base can run into a lower floor. Shut the valve and shut off power in that room if water reaches fixtures.
Shutoff valve that will not close
Turn off the main shutoff for the house and call.
Several fixtures backing up
When the tub and sink gurgle too, the problem may be on the main line. See sewer line cleaning.
If you smell gas anywhere, leave the house first and call the gas utility or 911.
What a toilet repair costs
Most toilet repairs are among the lower-cost plumbing calls. A new toilet installed typically runs $300 to $900 or more, depending on the model.
Toilet repair is rarely covered by insurance unless water damage followed a sudden failure. Coverage varies by policy. Call (855) 575-2890 for a clear price.
Permit rules and who does the work
Swapping a toilet in the same spot generally needs no major plumbing change, but permit rules vary, so ask the Mauldin Building and Zoning office at (864) 234-3475 if you are moving the toilet or the drain. The city says a permit is required before you add, alter or replace any plumbing system.
Visits across the area, including Taylors, go through the same 24/7 line.
Toilet repair questions from Mauldin homeowners
Yes. Dispatch at (855) 575-2890 is answered 24/7. Close the shutoff valve behind the toilet and a plumber can be booked for the same day when the schedule allows.
A flapper that no longer seals lets tank water slip into the bowl, so the fill valve tops it up. Replace the flapper first. Dye in the tank will show a leak if no color shows in the bowl after an hour.
Greenville Water uses chloramine as its disinfectant, which can age rubber parts sooner. Its water is also very soft, with a hardness average near 5.7 mg/L in 2026 reports, so mineral buildup is not the usual cause.
Usually yes, if water is spreading. A failed wax ring can soak the subfloor over days, so shut the valve and call.
Yes. A silent flapper leak can waste many gallons a day. A leak check on the meter, with all fixtures off for at least 15 minutes, helps separate it from other leaks. See leak detection if the meter still moves.
If it needs repeated repairs, has a crack, or is a pre-1994 high-flow model, replacing it usually costs less over time.
