An overflowing toilet: what to do in the next minute
If the bowl is rising toward the rim, lift the tank lid and push the flapper down, or close the supply valve behind the toilet by turning it clockwise. That stops more water coming in. Then call our 24/7 line, because an overflow that repeats may mean a main line problem.
Do not flush again, and put towels around the base. If sewage is coming up in a tub or floor drain as well, the blockage is further down, and you should stop using every fixture until the plumber arrives.
- Close the valve behind the toilet, turning clockwise.
- Lift the tank lid and press the flapper down if the bowl keeps filling.
- Stop flushing and keep children away from the water.
- Call the 24/7 line if the bowl does not drain after plunging.
The toilet problems we see most
Toilet calls fall into a few groups. Clogs top the list, followed by leaks at the base or tank, tanks that fill slowly or run constantly, and bowls that rock on the floor. Each has a different cause, and the repair ranges from a five-minute adjustment to a full replacement.
A toilet that runs on its own is usually a worn flapper or a fill valve, and a repair is often inexpensive. A toilet that leaks at the base usually needs a new wax ring or a repaired flange, and the plumber checks the floor for rot. A toilet that clogs every week points at a drain issue or an old low-flow model.

Symptom, likely cause and usual fix
This table helps you describe the problem when you call.
| What you notice | Likely cause | Usual fix |
|---|---|---|
| Water around the base | Failed wax ring or loose closet bolts | Reset the toilet with a new wax ring |
| Rocking bowl | Flange or floor damage | Repair the flange, check the subfloor |
| Runs constantly | Worn flapper or fill valve | Replace the parts |
| Weak flush | Clogged rim jets or low water level | Clean jets, adjust the fill level |
| Clogs weekly | Partial blockage or a downstream issue | Auger, then a camera if repeated |
Repair or replace?
A toilet is worth repairing when the porcelain is sound and the fix is a part. Replacement makes more sense when the bowl is cracked, the toilet is very old and uses far more water per flush than current models, or repairs have come twice in a year. The plumber explains both costs and lets you choose.
If you are putting in a new toilet, the details of the flange matter as much as the bowl. A flange set too low or cracked is a common reason for a toilet that rocks, and our plumbing installation page explains what a proper setting involves. A toilet on a floor with water damage may need subfloor work too.
What the plumber checks beyond the toilet
A toilet is the lowest point of the bathroom drain system, so it often shows the first sign of a larger problem. If a second fixture gurgles, or the water in the bowl rises and falls when the washer drains, the plumber checks the vent and the line. Sometimes the answer is a drain cleaning visit instead of a toilet repair.

Quick checks before you call
These checks take two minutes and give the dispatcher useful detail.
- Is water still running, or has it stopped after you closed the valve?
- Does the toilet leak at the base, from the tank or from the supply line?
- Do other fixtures gurgle or drain slowly?
- Is the floor soft or stained around the toilet?
- How old is the toilet, if you know?
Toilet Repair questions in Derry
Yes. Our line is open 24/7, including holidays. Close the valve behind the toilet, stop flushing and call (603) 815-9179. If sewage is also in a tub or floor drain, stop using every fixture.
The wax ring that seals the toilet to the flange has most likely failed, or the closet bolts are loose. The plumber lifts the toilet, checks the flange and subfloor, and reseats it with a new ring.
It depends on the condition. If the porcelain is sound and the fix is a flapper or a fill valve, repair is cheaper. If the bowl is cracked or repairs keep coming back, replacement usually costs less over time.
A flapper that no longer seals, a fill valve that does not shut off or a chain that is too long are the common causes. These are small parts, and the fix is usually quick.
Yes, if it happens often or if other drains are slow. The plumber clears the toilet and, when other signs appear, checks the main line with a cable or camera.
