running water noise when nothing in use

mutley74

Hi
in my new house (semi-detached) which is being refurbished, i can hear under the sink a running water flow noise through the pipes.

Main stop !!!! is under the sink, when turned off noise exists.

No other water uses when i check. Floorboard is solid concrete, so no risk of under floor leak.

No outside taps. Boiler is currently removed so no hot water use.
No noises from the toilets.

any suggestions, as don't want to incur a big repair bill if can be avoided,

Do you have a cold water tank in your attic?

Have you checked your water meter to see if dial is spinning?

Many years ago I had this too. In my case it turned out to be a leak in the supply pipe from the main to the house.

Is it a flat? There is a chance the mains in, is shared and branches off to you neighbours.

Can you turn off the water at the stop !!!! outside the building/house,if the noise stops it is a leaking pipe between the stop !!!! and your house.

water pressures have been fine, they were even tested by Home Link for a boiler quote. No signs of any flooding on the land or nearby.
