High Water Bill? 8 Signs of a Hidden Water Leak in Your Home
A water bill that suddenly doubles is one of the first signs of a hidden leak. In Riyadh villas, leaks often hide under floors, inside walls, in roof tanks or in the underground tank line, so you may not see any water at all.
Finding a leak early saves water, money and expensive damage to tiles, walls and foundations.
8 signs of a hidden leak
- Your water bill rises without any change in usage.
- The water meter keeps turning when every tap is closed.
- Damp patches, bubbling paint or stains on walls and ceilings.
- Loose, cracked or hollow-sounding floor tiles.
- A musty smell or mould in cupboards and corners.
- The water pump runs on its own when no one is using water.
- The ground or garden is unusually wet in one spot.
- Lower water pressure than usual.
A simple meter test you can do yourself
Close every tap in the house, make sure the washing machine and dishwasher are off, and check that toilets are not running. Write down the meter reading, or take a photo, then wait one to two hours without using any water.
If the reading changes, water is leaking somewhere between the meter and your taps. Next, close the valve that feeds the house from the tank. If the meter still moves, the leak is likely on the line between the meter and the underground tank.

Common leak locations in Riyadh homes
- Running toilets and worn flush valves, which waste a lot of water silently.
- Joints under kitchen and bathroom floors.
- The float valve and pipes of the roof tank.
- Underground tank walls and the supply line from the meter.
- Water heater connections and pressure relief valves.
How professional leak detection works
Modern leak detection does not mean breaking floors to search. Plumbers use pressure testing to isolate the leaking line, then acoustic listening devices and thermal cameras to find the exact point. Only a small area is opened for the repair.
Do not wait
Even a small leak under the floor can weaken tile adhesive, damage walls and raise moisture in the foundation. The longer it runs, the bigger the repair bill.
