Symptoms
Toilet repair: match what you see to the likely cause
Most toilet trouble falls into five groups. The cause decides whether it is a small repair or a bigger job.
-
Keeps runningTank
Water trickles into the bowl or the tank keeps refilling. A worn flapper that does not seal, a fill valve that does not shut off, or a float set too high are the usual causes. The parts are small and wear out.
-
Flushes by itselfPhantom flush
The toilet refills now and then with nobody near it. That points to a slow leak from the tank into the bowl, usually past the flapper. A running toilet can add to the water bill without making a sound.
-
Water at the baseFloor
Water around the foot of the toilet can come from the seal under the bowl, a loose connection at the tank, or the supply line. Wipe it dry and see where it comes back first.
-
Rocks or shiftsMounting
A toilet that moves is not held firmly to the floor. The bolts may be loose, the floor may be uneven, or the flange it sits on may be damaged. A rocking toilet can break its seal and leak.
-
Drip at the supply lineBehind the toilet
A small drip at the shutoff stop or the line that feeds the tank. It is easy to miss and can soak the floor over time.
A weak flush is a separate question. A flush that is weak because of a clog is covered on clogged toilet. If the bowl is clear and the flush is still weak, a low water level in the tank or a flapper that closes too soon may be the cause, and a plumber can check it.
Safe to do now
What to check before you call
These steps need no tools and do not take the toilet apart.
Find the shutoff stop
It is the small valve on the wall or floor behind the toilet, where the supply line enters. Turning it clockwise stops water to the tank. Turn it gently, and do not force it if it is stuck.
Dry it and watch
Dry the floor, the base and the supply line with a towel. Then see which spot gets wet again. That tells a plumber where to look.
Close the stop and listen
If the hissing or trickling stops when the stop is closed, the water was moving through the tank. That points to the fill valve or the flapper. Open the stop again afterward.
Check the other fixtures
If water stands on the floor at more than the toilet, or the smell is of sewage, the problem may be in the drain. See sewer backup.
If water is spreading and the stop will not close, close the main shutoff. Emergency plumber covers water you cannot stop.

Repair the toilet, or put in a new one
No single age or price decides it. A plumber weighs what is wrong against what the toilet is.
A repair usually makes sense when
- The fault is in the tank parts: flapper, fill valve or float
- A supply line or shutoff stop is leaking
- The seal under the bowl needs resetting, and the bowl and floor are sound
- The toilet otherwise flushes well
Replacement is worth a look when
- The bowl or tank is cracked or leaks through the china
- Repairs keep coming back
- It has never flushed well, even when clear
- You want a different height or shape
A cracked bowl or tank is generally a replacement, not a repair. Ask a plumber to compare a repair with a new toilet for your case. This page gives no prices or lifespans.
Installation
How a toilet installation usually goes
This is a general outline of the work. The plumber will explain the steps for your toilet.
Water off and toilet emptied
The stop is closed, the tank and bowl are drained, and the supply line is disconnected.
Old toilet lifted out
The bolts come out and the toilet is lifted off. The old seal is scraped away.
Flange and floor checked
The flange is the ring on the floor that the toilet bolts to. A plumber looks for damage or rot, and may fix the flange or floor before a new toilet goes on.
New seal and toilet set
A new seal goes on, the toilet is set level and bolted down, and the tank is attached if it is a two-piece model.
Supply connected and tested
The line is connected, the water is turned on, and the toilet is flushed several times while the joints are watched for drips.
Ask what the job includes before it starts: the new toilet, the supply line, the seal, disposal of the old toilet, and any floor or flange work.
Water under the toilet
When a small leak has already done damage
A toilet that leaks for weeks can soften the floor around it. Signs are a spongy spot, lifting flooring, a stain on the ceiling below, or a musty smell.
If the water on the floor does not trace to the toilet, or a stain shows up somewhere nearby, the water may be coming from a pipe you cannot see. Leak detection explains how that kind of leak is found. Questions about damage and coverage go to your insurance company.
Nearby fixtures
The sink and shower in the same bathroom
A bathroom often has more than one worn fixture, and the same shutoff and supply questions apply. Faucet and shower repair covers drips, weak flow and shower valves.
Tell the plumber
- What the toilet does: runs, leaks, rocks, or will not flush well
- Where the water appears, and whether it comes back after you dry it
- Whether the shutoff stop closes
- How long it has been going on
- Whether you want a repair price or a new toilet quoted
FAQ
Toilet repair in Greeley: common questions
Why does my toilet keep running?
Most often the flapper no longer seals, the fill valve does not shut off, or the float is set too high. Water keeps leaking from the tank into the bowl, so the tank keeps refilling. These are small parts, and a plumber can replace them.
Why is my toilet leaking at the base?
The seal under the bowl may have failed, the toilet may have come loose, or water may be dripping from the tank or the supply line and running down. Dry everything and watch where the water returns. If it is at the base itself, a plumber may need to lift the toilet and reset the seal.
Why does my toilet rock?
It is not held firmly to the floor. The bolts may be loose, the floor may be uneven, or the flange underneath may be damaged. Rocking can break the seal and cause a leak, so it is worth having it looked at.
Should I repair or replace the toilet?
Worn tank parts, a bad supply line or a failed seal are usually repairs. A cracked bowl or tank, or a toilet that never flushes well, points to replacement. Repeated repairs are a reason to compare the two.
What does toilet installation involve?
The old toilet is removed, the flange and floor are checked, a new seal and toilet are set and bolted down, and the supply line is connected and tested for leaks. If the flange or floor is damaged, that adds work. Ask what is included before the job starts.
What should I do while waiting for a plumber?
If water is spreading, close the toilet's stop valve behind it, or the main shutoff if the stop will not close. Mop up standing water and note where it shows, at the base, the tank or the supply line.
