It is possible to identify a water leak in your home, even though you can’t see any water anywhere.
Check your water usage often, and this means you can easily see any sudden raises that you can’t associate with a cause (such as having guests or watering your garden more in warm weather ), which could be a signal of a leak. Sign-up for an account or ask your water provider to send you regular monthly statements, which means you will keep an eye on the water you are using.
Realizing a leak in water pressure when you are filling up the shower or going for a shower may be an indicator of the leak. You can verify this by turning off all of your fixtures then turning one back again. If the pressure is greater than it was, it is most likely a leak.
But in a shower, low pressure may also be due to a clogged showerhead because of a build-up of limescale. If your shower has stopped your bath, you might have a defective shower or shower diverter. You could clean your showerhead using a limescale remover and frequently check the shower or shower diverter to find out if this is helpful.
Monitor when a hot water heating unit/boiler occurs – if it is on nearly continuously, you might have a leak in your water pipe. These will be underground and may be harder to detect than other leaks.
