A hidden water leak can run for months before anyone notices. By the time it shows up as a stain on the ceiling or a soggy patch in the yard, it may have already wasted thousands of litres of water and caused damage to timber, plaster, or foundations.
Catching a leak early saves water, money, and repair bills. Here are the five most common signs Wellington Point and Brisbane bayside homeowners notice first.
1. Your water bill jumps for no obvious reason
A sudden increase in your water bill is often the first clue. If your usage has not changed but your bill has, water is going somewhere it should not. Compare the current bill to the same time last year, and check the daily usage figure rather than just the dollar amount.
Even a small leak, like a dripping tap running at one drip per second, can waste around 12,000 litres a year. A cracked pipe under the slab or in a wall can waste far more.
2. Damp patches, mould, or bubbling paint
Water takes the path of least resistance. It might show up as a brown stain on the ceiling, bubbling paint on a wall, or a musty smell in a cupboard. Mould grows where moisture sits for more than 48 hours, so any persistent mouldy spot deserves investigation.
In Queensland's humid climate, condensation can also cause mould, but if the damp patch is localised or growing, a leaking pipe is a likely cause.
3. You hear running water when everything is off
Turn off every tap, the dishwasher, the washing machine, and any irrigation. Go to the water meter and listen. If you can still hear water moving through the pipes, or the meter dial is slowly turning, water is flowing somewhere in or under your home.
This is one of the simplest checks you can do and it often confirms a leak before any damage is visible.
4. Low water pressure at one or more taps
A drop in water pressure at a single tap usually means a localised problem like a clogged aerator or a failing tap washer. If the pressure drops across the whole house, the cause is more likely a leak or a break in the main supply pipe.
Pressure that comes and goes, or drops when another tap is turned on, can also point to a leak that is letting water escape before it reaches your fixtures.
5. Cracks in paving, walls, or doors that will not close
Underground leaks saturate the soil and can cause paving to lift, brickwork to crack, or doors to stick as the ground shifts. A constantly wet patch in the lawn or garden, especially during dry weather, is another strong sign of a leaking water main or garden tap pipe.
Some movement is normal in Brisbane's clay soils, but new or worsening cracks combined with damp ground should be checked.
What to do if you suspect a leak
Start with the meter test. Turn off all water inside and outside the house, then watch the meter for a few minutes. If the numbers are still moving, you have a leak.
Next, look for the obvious culprits: running toilets, dripping taps, and leaking garden taps. If you cannot find the source, call a licensed plumber with leak detection equipment. We use acoustic listening devices and thermal imaging to locate hidden leaks without tearing walls or concrete apart.
The sooner a leak is found and fixed, the less damage it can do. If you are in Wellington Point, Redlands, or anywhere along the Brisbane bayside and suspect a hidden leak, give us a call and we will track it down.
