Water Running Noises

Rozmo

constant water running noise as if water is running somewhere in the house but have checked all toilets, sinks, outdoor hoses and cannot find leak. *If I turn off the main water shut off valve in the basement which is where the noise is the loudest, the noise stops.

If you have a meter, check and see if the dial is moving when everything is "off".
You have something that is leaking if the sound disappears when you shut the main off.

Does the noise stop completely?
Have a plumber come out and check it.
Post a picture/s of the valve you're referring to.
Any evidence of water anywhere?

I don't know how you checked toilets are anything else in house, but if you just looked at toilets for overflowing they can also leak out under flapper and it can be deceiving. My suggestion would be to go to each fixture and appliance and turn them off one at a time. If you can't locate source that way you may have to call a plumber. I guess you've checked the yard?

Faulty valves or crack in water lines to washer? Do you have an irrigation system without its own cut-off valve? Might have a fractured diaphragm or something in one of the irrigation valves or the little screw for manually overriding a valve may have come loose just a bit.

go and shut off each fixture by its own shut off one at a time and listen after each valve is shut down to see if noise stops ....you should find the problem,,,
