Running Water Sound In A Wall
Hiss or flow noises behind finishes usually mean water is moving where it should not.
A continuous hiss behind a wall is often a pressured line losing water. The sound is strongest near the leak, which makes it locatable without opening everything.
What to check yourself
- Note whether it is constant or tied to fixtures
- Listen at different times of day
- Check the meter to confirm active loss
Likely causes
- A supply line leak in the wall
- A drain line running constantly, such as a failed toilet valve
- A hydronic loop passing water
What the investigation does
- Acoustic listening and correlation
- Isolation to confirm the line
- A located opening point for repair

Quick answers
What should I do first about this?
Acoustic listening and correlation
Can this be fixed without opening everything?
In most cases the investigation narrows the target before any finish is opened. Small access points are sometimes needed to confirm a finding, and that is discussed before anything is opened.
