A running toilet is the only plumbing fault that bills you every single day and never gets urgent enough to fix.
That's exactly why it doesn't get fixed.
There's no flood, no damage, nothing on the floor — just a faint hiss you stopped hearing weeks ago, and a cistern quietly refilling itself around the clock. A silent leak past a worn flapper can pass a genuinely startling volume of water in a month, and every litre of it is metered.
Meanwhile the actual repair is usually a part costing very little and a visit measured in minutes.
That gap — between what it costs to ignore and what it costs to fix — is the largest of any fault in the property.

Before you call, five minutes and a bottle of food colouring settles the most common question there is.
Water is passing from the cistern into the pan without a flush. That's a leaking flush valve or flapper seal, it's running continuously, and it's on your bill right now. It's also among the cheapest repairs in plumbing.
The cistern isn't leaking into the pan — and if you can still hear refilling, the fill valve is overfilling into the overflow instead. Different part, similar cost, same continuous waste.
Either way you've narrowed it before anyone arrives, which shortens the visit and the bill.
And if you have several toilets, run the test on all of them. Households frequently find the running one isn't the one they suspected.
Flapper or flush valve seal not sealing, or a fill valve set too high and discharging into the overflow. The dye test separates the two.
Frequently mineral build-up blocking the rim holes and siphon jet rather than a fault in the mechanism. Also a flapper closing too early, or a cistern water level set below where it should be.
Usually the same causes — insufficient volume reaching the bowl fast enough.
Either something is caught in the trapway, the flush is too weak to clear the pan properly, or the problem isn't the toilet at all but the drain it discharges into. Repeated blockages in one toilet while everything else drains normally point at the pan. Repeated blockages alongside slow drainage elsewhere point past it.
Several possibilities with very different costs: a failed pan seal, a cracked pan, a leaking supply connection, a failed cistern-to-pan seal, or simply condensation on the cistern in humid weather. Establishing which comes before anything is lifted.
Loose fixings, a floor that's no longer flat, or a pan seated on a failed seal. Worth acting on quickly — every movement works the seal further, and a leaking pan seal discharges under the floor where you can't see it.
Frequently a venting problem or a partial blockage downstream rather than a fault in the toilet.
Points at the drain line rather than the toilet.
Condensation, common in humid conditions, and easily mistaken for a leak. Addressable, and not a repair.
Fill valve passing water. Always worth investigating — it's the sound of the meter turning.
A single blocked toilet with everything else draining normally is frequently cleared with a proper flange plunger — the kind with an extended rubber sleeve, 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.
There are only a handful, and almost every toilet fault is one of them.
A rubber component sitting in water permanently, warping and hardening with age and with in-cistern cleaning blocks. The single most common cause of a continuously running toilet, and among the cheapest parts in the building.
Refills the cistern and shuts off at the set level. Fails by not shutting off — sending water into the overflow indefinitely — or by filling slowly, or by shrieking as it does. Straightforward to replace.
Sets the shut-off level. Misadjusted, waterlogged, or fouled, and the cistern either overfills or never fills enough for a proper flush.
Mechanical parts that wear, seize, or break. Cheap and quick.
Where the seal sits. Corroded, scaled, or pitted, and no new flapper will seal against it. This is why replacing a flapper sometimes doesn't fix the leak — the sealing surface itself has failed.
Where a two-piece toilet joins. Leaks here appear between cistern and pan, and are frequently misread as a pan seal failure.
Between the pan and the drain flange. Fails through age, movement, or an unstable floor, and it leaks under the pan where nothing is visible until damage appears in the floor or the ceiling below.
The fitting the pan bolts to. Corroded, cracked, or set at the wrong height relative to a new floor covering — a common cause of a pan that won't sit properly and a seal that keeps failing.
Flexible hoses have a service life and fail without warning. Isolation valves seize when they're never used.
Not a part failure at all, but the most common cause of a weak flush — and it's cleaning rather than replacement.
Most toilets are worth repairing. Some aren't, and the line is clearer than with most fixtures.
Flappers, fill valves, floats, handles, and seals are inexpensive parts on a ceramic body that has no service life to speak of. Ceramic doesn't wear out — the mechanism inside it does.
Replacement deserves consideration when:
Age alone. A twenty-five-year-old toilet with a sound pan and a worn flapper needs a flapper.
In a property with several toilets, the one you suspect frequently isn't the one costing you money.
A new flapper against a corroded valve seat leaks exactly as much as the old one did. This is why some toilets get "fixed" twice.
Pan seal, cistern seal, supply connection, cracked pan, or condensation — five different causes, five different jobs.
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 — not a fresh seal on an unstable pan.
Repeated blockages in one toilet while everything else runs fine is a toilet problem. Repeated blockages with slow drainage elsewhere isn't.

Food colouring in the cistern, don't flush, wait thirty minutes, and look in the bowl. Colour in the bowl means water is passing from cistern to pan without a flush. Run it on every toilet — the culprit is often not the one you suspected.
Then the flapper probably wasn't the whole problem. The seat it closes against can be corroded, scaled, or pitted, and a perfect new seal against a damaged sealing surface still leaks. That's the single most common reason a toilet gets "fixed" twice.
Three possibilities. Something is lodged in the trapway; the flush is too weak to clear the pan properly, usually from mineral build-up in the rim and jet; or the problem is in the drain beyond the toilet. If other fixtures are also slow, it's the third one.
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 the ceiling below shows damage. It's usually fixings, flange height, or an uneven floor — all fixable.
Please don't. It sits in standing water in the pan achieving very little against paper or an object, it can damage the ceramic glaze and seals, and it creates a hazard for whoever has to clear 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 draining fine, it's worth ten minutes before booking.
Rarely. The most common cause is mineral build-up blocking the small rim holes and the siphon jet, which is cleaning rather than replacement. A flapper closing too early or a low cistern level produce the same symptom.
Usually not. Ceramic doesn't wear out — the parts inside do, and they're inexpensive. Replacement makes sense where the pan is cracked, parts are unavailable, the flange or floor needs work anyway, or you want a different height or style.
That's condensation, common in humid conditions, and it can drip enough to look convincing. It isn't a fault, and it's addressable — worth mentioning on the call so we bring the right answer.
Yes. They need access through the panel or frame, which takes longer than a freestanding unit, and it's worth knowing beforehand so the visit is planned rather than improvised.
A running toilet costs money quietly, every day, and never becomes urgent — which is precisely why it goes unfixed for months. The repair is almost always a small part. The delay is what gets expensive.
RedLine Plumbing finds which toilet is actually running, checks the sealing surface rather than just fitting a new seal against a damaged one, establishes where floor water is really coming from, and reseats pans so the fix holds.
