Is your consumption abnormally high and you suspect a leak in your system? Here are some tips to help you spot the leak and avoid nasty surprises on your bill.
Read your meter from time to time before going to bed. Make sure that no one turns on a tap or flushes the toilet. Also ensure that all water-consuming machines are switched off (dishwashers, washing machines, etc.).
The next day, start your day by recording the numbers. If there is a difference, there is probably a leak in your system. Carry out a thorough check of your entire system.
We recommend that you carry out this check several times a year.
Who is responsible if there is a leak?
Also check the condition of your boiler's safety valve. When the pressure inside the boiler exceeds the setting limit of the safety valve, the valve opens and lets a small volume of water flow out. If this valve becomes dirty and worn, it may remain stuck in the open position and water will continuously flow out of the boiler.
Make sure that the water flow is visible so that you can easily check the valve opening.
To stop the leak, contact your installer.
When you have flushed the toilet and the tank is full, check that the water flow down the sides has stopped. If the flow persists, your flush mechanism is defective and needs to be replaced.
If you are still unable to locate the leak, contact your plumber without delay.
