Common Causes of Water Leaks at Home

Hidden leaks under sinks

The cupboards under kitchen and bathroom sinks are one of the most common leak spots. Flexible hoses, waste traps and shut-off valves all live in a dark, humid space, so small leaks can go unnoticed for weeks. Check for:

• Damp cardboard, warped wood or peeling paint inside the cupboard
• A musty smell every time you open the door
• Rust around metal fittings
• Green or white deposits on brass valves

Toilet leaks

Toilets can leak silently for months. The most common cause is a worn flush valve that lets water trickle from the cistern into the bowl continuously. A simple test is to add a few drops of food colouring to the cistern and wait 15 minutes — if colour appears in the bowl without flushing, there is a leak. Fixing it usually only takes replacing a small rubber seal.

Pipe and valve leaks

Pipes and valves inside walls, under floors or above ceilings can develop pinhole leaks or drip from joints. Warning signs include unexplained damp patches, paint bubbling, tiles becoming loose, or the sound of running water when everything is turned off. A plumber can use leak detection tools to find the exact spot without breaking walls unnecessarily.

Water tank leaks

Roof tanks fail from age, sun damage and internal corrosion. Look for water pooling on the roof around the tank, or damp patches on the ceiling directly below. A small tank leak often becomes a large one very quickly, so tank leaks should always be inspected without delay.

Why early leak detection matters

Small leaks are cheap to fix. Big leaks damage floors, ceilings, walls and furniture and can trigger insurance claims. If your water bill has jumped for no reason, you can hear running water in the walls, or you see any unexplained damp, call a plumber for a proper leak detection Limassol service. Acting early always saves money.
