Every toilet fault falls on one side of a line, and the line is the rim of the pan.
Above it — inside the cistern — everything is clean water, cheap parts, and easy access. Flappers, fill valves, floats, handles. A running toilet wastes money, but nothing about it damages your building, and the repair is measured in minutes and small parts.
Below it — where the pan meets the floor — everything is waste water, hidden, and structural. A failed pan seal doesn't puddle helpfully in front of you. It discharges under the pan, into the floor, and you find out weeks later when the boards go soft or a stain appears in the ceiling below.
Same fixture. Two completely different categories of problem.
Which is why the useful thing to establish first isn't what the toilet is doing — it's where the water is. Inside the cistern, in the bowl, or on the floor.

Everything in the cistern is clean water and inexpensive parts. These cost money continuously and damage nothing.
The flapper or flush valve seal isn't sealing, or the fill valve is set too high and discharging into the overflow. A silent leak past a worn flapper passes a startling volume every day, all of it metered — and it's simultaneously the most expensive fault to ignore and one of the cheapest to fix.
Put a few drops of food colouring in the cistern, replace the lid, don't flush, wait thirty minutes, then look in the bowl. Colour in the bowl means the flapper is passing water. Clear bowl with refilling still audible means the fill valve is overfilling into the overflow instead. Run it on every toilet — households frequently find the culprit isn't the one they suspected.
Most often mineral build-up blocking the small rim holes and the siphon jet — cleaning rather than replacement. Also a flapper closing too early, or a cistern water level set below where it should be.
A restricted fill valve or a partly closed isolation valve.
Fill valve passing water. Always worth investigating — it's the sound of the meter turning.
Mechanical wear.
The seat it closes against can be corroded, scaled, or pitted. A perfect new seal against a damaged sealing surface leaks exactly as much as the old one did — which is the single most common reason a toilet gets "fixed" twice.
Everything at floor level involves waste water and building fabric. These are the ones that get expensive quietly.
The seal between the pan and the drain flange. It leaks underneath the pan — into the floor, the joists, and the ceiling below — with nothing visible until damage appears. The most consequential fault a toilet has, and the least obvious.
Loose fixings, an uneven floor, or a pan sitting on a failed seal. Every movement works the seal further, so a rocking toilet is a pan seal failure in progress rather than a nuisance.
The fitting the pan bolts to — corroded, cracked, or set at the wrong height relative to a new floor covering. A frequent underlying reason a seal keeps failing after being replaced, and the reason some toilets get resealed repeatedly by people who never looked at the flange.
Hairline or otherwise. Ceramic cracks don't stop, and one below the waterline is a leak with a schedule.
Five possible causes with wildly different costs: the pan seal, the cistern-to-pan seal, the supply connection, a cracked pan, or condensation on the cistern in humid weather. Establishing which comes before anything is lifted.
Frequently a failed seal letting drain air past, rather than anything you can see.
A single blocked toilet with everything else draining normally is frequently cleared with a flange plunger — the kind with an extended rubber sleeve that seals into the pan outlet, not a flat sink plunger.
Don't keep flushing, and don't pour chemical drain cleaner into a pan holding standing water. Neither helps, and both make the eventual visit worse.
And if several fixtures are slow, it isn't the toilet at all — that's a drain problem, and worth saying on the call.
Three different causes producing one symptom, and they're separable before anyone arrives.
The S-bend inside the pan. Typically a foreign object, a build-up of wipes, or excessive paper. A flange plunger or a closet auger reaches this, and it's the most common cause by far.
Insufficient water arriving fast enough to carry waste through the trapway. Usually mineral build-up in the rim holes and jet, a flapper closing early, or a low cistern level. The toilet blocks because it never had the force to clear itself.
Not a toilet fault at all. The test is whether anything else is affected — if other fixtures are slow, or if the bath gurgles when you flush, the obstruction is downstream and the toilet is just the first thing to show it.
Which is why "it keeps blocking" needs one more question: does anything else in the property drain slowly? Yes points past the toilet. No points at the pan or the flush.
Most toilets are worth repairing, and the line is clearer than with most fixtures.
Repair Is Almost Always Right
When the fault is a cistern componentFlappers, fill valves, floats, handles, and seals are inexpensive parts on a ceramic body with no meaningful service life. Ceramic doesn't wear out — the mechanism inside it does.
Replacement deserves consideration when:
What Shouldn't Drive It
Age aloneA twenty-five-year-old toilet with a sound pan and a worn flapper needs a flapper.
Cistern, bowl, or floor. That sorts a cheap running toilet from a seal discharging into your floor structure.
A new flapper against a corroded valve seat leaks exactly as much as the old one. This is why some toilets get fixed twice.
Because a pan seal that keeps failing is usually reporting the flange beneath it, and replacing the seal alone just restarts the clock.
If anything else in the property is slow, the toilet isn't your problem and shouldn't be billed as one.
Ceramic doesn't wear out. Most of the time you need a part, not a fixture.
A pan that rocks will fail its seal again. Fixings, flange height, and a level base are the repair.

Water at the floor means waste water and building fabric, and a failed pan seal discharges under the pan where you won't see it until the floor or the ceiling below tells you.
More than people expect. A silent leak past a worn flapper passes a substantial volume every day, continuously, and all of it is metered. It's the most expensive fault to ignore and one of the cheapest to fix.
Food colouring in the cistern, don't flush, wait thirty minutes, look in the bowl. Colour in the bowl means water is passing from cistern to pan without a flush. Test every toilet — the culprit is often not the one you suspected.
Then the flapper wasn't the whole problem. The seat it closes against can be corroded, scaled, or pitted, and a perfect new seal against a damaged surface still leaks. That's the commonest reason a toilet gets "fixed" twice.
Don't assume it's the pan seal. It could be the supply connection, the cistern-to-pan seal, a cracked pan, or condensation on the cistern in humid weather. Those range from a five-minute fix to a replacement, which is why establishing it first matters.
Worth acting on quickly. Every movement works the pan seal, and once that fails it discharges under the pan where you won't see it until the floor or ceiling below shows damage. It's usually fixings, flange height, or an uneven floor.
Then the seal probably isn't the problem — the flange beneath it is. A corroded, cracked, or wrong-height flange gives a new seal nothing sound to work against, and replacing the seal alone just restarts the clock.
Three possibilities: something lodged in the trapway, a flush too weak to clear the pan, or a problem in the drain beyond it. The test is whether anything else in the property drains slowly. If it does, the toilet isn't your problem.
Please don't. It sits in standing water achieving very little against paper or an object, it can damage the glaze and seals, and it creates a hazard for whoever clears it properly.
Yes, if it's the right one. A flange plunger with an extended rubber sleeve seals into the pan outlet; a flat sink plunger doesn't and won't work. On a single blocked toilet with everything else fine, it's worth ten minutes.
Rarely. The most common cause is mineral build-up blocking the small rim holes and the siphon jet — cleaning rather than replacement. A flapper closing early or a low cistern level produce the same symptom.
That's condensation, common in humid conditions, and it drips enough to look convincing. It isn't a fault, it's addressable, and it's worth mentioning on the call so we bring the right answer.
Above the rim is clean water, small parts, and a bill that runs quietly until someone fixes it. Below the rim is waste water, hidden discharge, and damage you find out about weeks later. The fixture is the same; the stakes are not.
FlowPoint Plumbing asks where the water is first, checks the sealing surface rather than just fitting a new seal against a damaged one, looks at the flange before resealing a pan, and tells you plainly when the blockage is in the drain rather than the toilet.
