Why does it sound like the water is still running if you turned it off at the wall by the toilet?

If it sounds like the water is still running after you've turned it off at the wall by the toilet, it could be due to residual water draining from the toilet tank or pipes. Additionally, the toilet's fill valve may be malfunctioning, causing it to continue to fill or make noise even when the supply is shut off. Another possibility is that there could be a leak or a problem with the Plumbing elsewhere, creating a sound that resembles running water. Checking the fill valve and ensuring there are no leaks can help identify the issue.
