Apprentice answer

Can you install a duct sound attenuator if the internal media got wet

A wet sound attenuator is not just dirty material; the media can lose performance and create mold risk. Hold it, document it, and get replacement or manufacturer direction.

Plain-English answer

Sound attenuators depend on internal acoustic media. If that media gets soaked in the yard, it can lose performance and become a contamination/mold concern in the airstream.

Do not hang wet sound traps just to keep schedule moving. Photograph the condition, tag the unit, protect the opening, notify the foreman/GC, and follow manufacturer/spec direction on replacement, drying verification, or rejection.

Ask Foreman

The sound attenuator for [location/tag] got soaked before install. I checked the casing/media and documented it. Do you want this rejected/replaced or held for manufacturer direction?

Verify before acting

Use this as training guidance. Foreman direction, approved drawings, project specs, manufacturer instructions, employer safety policy, and AHJ/code requirements always control the final answer.
