Leaking toilet repair in Macclesfield
In short
Water on the floor around a toilet comes from one of four places: the pan connector at the back, the seal between cistern and pan, the supply connection into the cistern, or condensation on the cistern itself. Which one it is determines whether it is a ten-minute fix or a pan that needs lifting.
Also called: water around base of toilet · toilet leaking from bottom · cistern leaking · toilet leaking onto floor
Signs you need this
- Water around the base of the pan, especially after flushing
- Water running down the back of the pan from the cistern
- A toilet that rocks or moves when used
- A persistent damp smell in the bathroom
- A stain appearing on the ceiling below the bathroom
Start with when the water appears. A puddle only after flushing points at the pan connector or the cistern-to-pan seal, because those only see water when the flush passes. Water present constantly points at the supply side — the fill valve tail, the isolation valve or the flexible connector. Water that appears in cold weather and never leaves a trail is often condensation running off a cold cistern onto the floor, which is not a leak at all.
The doughnut seal between a close-coupled cistern and pan is a common failure, and it is easy to spot: water runs down the back of the pan on every flush. Replacing it means lifting the cistern off, which is straightforward but needs the cistern drained and the fixing bolts freed — and those bolts are often corroded on an older suite, in which case the fixing kit gets replaced too.
The pan connector is the other frequent culprit. Flexible connectors perish, rigid ones crack if the pan has been rocking, and a pan that is not properly fixed to the floor will work any connector loose over time. That last point matters: a toilet that moves when you sit down is not a comfort issue, it is the cause of the leak.
The leak that does real damage is the slow one at the pan connector, because it goes backwards under the pan and into the floor rather than out where it can be seen. In a bathroom with a timber floor this rots joists and boarding, and the first symptom is often a stain on a ceiling downstairs rather than anything visible in the bathroom itself.
Foul water on a floor needs treating as contaminated: gloves, disinfect afterwards, and replace anything porous that has soaked it up rather than trying to clean it.

What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your plumber has to honour it. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
Why does my toilet leak only when flushed?
Because the leak is on the part that only carries water during a flush — the cistern-to-pan seal or the pan connector at the back. Both are routine replacements.
The cistern is wet all over but I cannot find a leak.
That is usually condensation. Cold mains water chills the ceramic and moist bathroom air condenses on it, then runs to the floor. Better ventilation and, in some cases, an insulated cistern liner solve it.
