The leak with no sound, no puddle and no clue

Most leaks give you something. A stain, a drip, a damp cupboard, a noise at night. The one that costs households the most gives you nothing at all, because the water is going exactly where water from that fixture is supposed to go.

A cistern that is passing water into the pan runs continuously. Not when you flush, but always. There is no sound, nothing on the floor, and nothing about the bathroom that looks wrong, which is why these run for years and turn up only as a bill that seems higher than it ought to be.

Two checks find it and both are free. Lift the lid off the cistern and look at the water level: if it is sitting at or above the top of the overflow tube, water is going down that tube right now. And put a few drops of food colouring in the cistern, leave it twenty minutes without flushing, and see whether colour appears in the bowl.

The repair is at the cheaper end of everything on this site. Usually an inlet valve, an outlet valve or the seal between cistern and pan. It is the diagnosis nobody does, rather than the repair nobody can afford.

Local leak guide

Leaks in a Cherrybrook home

Look at the water level first

At or above the top of the overflow tube means it is running down it now.

Ten seconds, and it needs no tools at all.

Then use food colouring

A few drops in the cistern, twenty minutes untouched, and watch the bowl.

Colour in the bowl is a definite answer rather than a suspicion.

It runs around the clock

Not on flushing. Continuously, which is what makes a small pass significant.

And it has almost certainly been doing it for a long time.

The repair is small

Inlet valve, outlet valve, or the seal between cistern and pan.

None of those are large jobs and none of them are expensive.

A creeping meter confirms it

Everything off, and a moving smallest dial means water is genuinely leaving.

In a house with no visible leak, the toilet is where to look first.

How a leak call-out runs.

Step 01

We ask about the toilets

On a bill that has climbed with nothing visibly wet, that is the first question rather than the last one.

Step 02

Testing a cistern for an internal leak in Cherrybrook

Tested on site

Food colouring in the cistern, the water level against the overflow, and the meter with everything closed.

Step 03

Located with equipment

Where it is not the toilet: acoustic listening, pressure testing and thermal imaging until it is a point.

Step 04

Repaired and written up

What failed, where, and what it took, at the figure agreed before we started.

What Cherrybrook locals ask us before booking a plumber.

How do I know if my toilet is leaking internally?

Put a few drops of food colouring into the cistern, then leave it alone for twenty minutes without flushing. If colour appears in the bowl, water is passing from the cistern into the pan continuously. It is the simplest diagnostic in plumbing and it costs whatever food colouring costs.

Is there another sign?

Yes, and it takes ten seconds. Lift the cistern lid and look at the water level. If it is sitting at or above the top of the overflow tube, water is running down that tube into the pan every minute of every day.

How much water does that actually waste?

Enough to show on a bill, and it is genuinely continuous, which is what makes it significant. We are not going to put a number on your particular household because that depends on how badly it is passing, but it runs twenty four hours a day and it has probably been running for a long time.

Why does nobody notice?

Because there is nothing to notice. No sound, no puddle, nothing on the floor. The water goes exactly where water from a toilet is supposed to go, just continuously instead of when you flush. It is the most common invisible waste in a house.

Is it expensive to fix?

It is one of the cheaper jobs on the list. Usually an inlet valve, an outlet valve or the seal between the cistern and the pan, and none of those are large pieces of work.

A pipe has burst. What first?

Turn the water off at the meter before anything else, then ring. How much a burst costs is almost entirely decided by how long the supply stayed on.
